BOLTING AND INSTALLATION INSTRUCTIONS

ZP300 standard flange configuration is “flanged” where port flange mounting holes are drilled and tapped. Flange mounting holes in chest area are limited to a depth of 1 x flange bolt diameter. It is recommended that studs be used on all flange mounting holes in chest area.

WARNINGCare must be taken when installing studs or bolts in tapped flange holes in chest area to prevent damage to internal wall profile.

NOTE Optional through bolting configurations are also available.

ZP300 Series valves are design to suit flanges compliant to ASME B16.5 and B16.47, and gaskets designed to ASME VIII-1 Appendix 2, and ASME B16.20 and B16.21. Torque on Flange bolt should not exceed values shown in Table 1.

4. Packing assembly: the packing gland bolts should be checked and adjusted to obtain a first time packing seal. Packing gland nuts may become slightly loose when valve is shipped. Field adjustment is expected and desired. (Figure 1. Tighten just enough to stop any leakage. Overtightening may increase valve operating torque and shorten packing life).

* Face to face dimensions per MSS SP-135 long pattern

1. Examine entire valve and report any damage or discrepancies immediately.

2. Accessories, if any, including solenoids, limit switches, positioners, etc., are tested for functionality prior to shipment. Examine carefully for damage which may occur during shipment.

3. Operators: standard manual hand wheels may be shipped loose for field installation.It is necessary to use a pipe wrench or large crescent wrench to properly tighten the hand wheel retaining nut. Be sure to fully tighten.

BG actuators.3. Lockout pin on both open and closed

positions standard on hydraulic cylinder actuators

4. Lockout pin style for open and closed positions are optional for MH valves.

5. Energy lockouts for hydraulic cylinder actuators.

Safety1. Pin-style lockouts will assume potential

energy of actuator has been removed through other means and are designed to prevent gate movement caused by line pressure. They are not designed to overcome or resist an energized hydraulic cylinder actuator.

2. Pin-style lockouts positions will be designed to resist unauthorized manual unassisted operation of the valve and prevent gate movement caused by line pressure.

3. Pin style lockouts not available on BG actuated valves.

For sizes NPS 26 and above consult sales for detail

OPERATIONAL CONSIDERATIONS

operate due to torque requirements, it is recommended that the valve be supplied with or converted to a bevel gear, air/hydraulic cylinder or electric motor actuator.

6. Electric motor actuated valves should be left in their factory set condition unless the system operating parameters dictate a change. If changes are necessary, they should be performed in small increments using the lightest/lowest setting possible to achieve the desired performance and then the valve/actuator function inspected. Excess torque and/or thrust in the motor settings may damage or lockup the valve.

7. The ZP300 valve is position seated and should never be torque seated. Do not use the motor torque settings to seat the valve.

8. Care should be taken to ensure that electrical motors are wired correctly. Incorrect phasing of 3-phase wiring may cause valve/motor damage.

NOTELockout design may vary between sizes. All lockouts include a pin to secure lockout in position and lanyard to tie lockout pin to valve body.

1. All valves should be operated within their design pressure and temperature ranges. Under no circumstances should the valves be operated at conditions outside these parameters.

2. The operator should have an understanding of the effects of opening/closing the valve with regards to its role in the overall piping system. Take caution to ensure that the valve is in good operating condition prior to operating it under pressure.

3. Care should be taken when processes contain hazardous and/or otherwise unstable media to ensure the operator is aware of the specific health and safety risks associated with that medium.

4. Stand clear of any moving parts such as the stem and/or gate assembly when operating, use of gloves is suggested when operating manual valves to minimize the risk of injury.

5. All manual handwheel operated valves are designed for hand input. Do not apply excessive input torque via pipe wrenches, 'cheater bars', or other devices. If a manual handwheel actuated valve is difficult to

FLOW RING ROTATION

An external flow ring can be rotated three times (3 x 90˚) after original installation. Four ASTM A574 steel, zinc plated socket head cap screws (SHCS) are required to position a ring and compress an o-ring gasket that seals the flow ring to the valve body. Sufficient tapped holes are provided in the valve body so that positioning holes are only used once per rotational position of a flow ring.

GENERAL MAINTENANCE

Emerson recommends that all Clarkson ZP300 series valves be inspected every 60 days. The following points should be examined and corrected as required:

WARNINGIf valve is not in line the gate must be open or partially open to avoid damage to valve and flow ring.

1. Cylinder rods, rod boots: look for excessive corrosion, bitumen build-up, tears in rod boot, etc. Check rod boot connections. Check for cylinder rod seal blow-by.

2. Packing gland: check for leaks or worn packing. If leakage is occurring around the packing gland, tighten the packing gland bolts evenly at all points, being careful not to overstress the bolting. (On some valves this will require two wrenches, one to tighten the nut and the other to hold the packing bolt from turning.) If the valve requires repacking, see additional instructions for repacking on page 6.

3. Flow rings: the valve must be out of line to properly examine flow rings. Look for erosion of hard surfacing and base metal. If base metal is exposed under the hard surfacing, ring should be replaced. If no erosion of base metal, ring may be rotated so worn area is moved from wear path to gain additional service life.

4. Resilient seats: examine seat for cracks, cuts, corrosion, erosion or swelling. Evidence of any above defects may justify replacement if seat has recorded evidence of leaking when closed, or condition is assessed by maintenance engineer to be at risk of pending failure. To replace a seat disassembly of valve is required.

5. If possible stroke the valve through the full open and closed position to make sure it is functioning properly.

NOTES1. Stop all small leaks as soon as possible as

considerable damage can be done to the valve and the surrounding area if leakage is allowed to continue.

2. Replacement parts including replacement liners, hand wheel and yoke assemblies, gates, packing glands, and packing can be provided from our factory. If valve requires further repair, please contact our office for an estimate of feasibility and cost of repair.

REPACKING INSTRUCTIONS

1. Each packing piece is cut a bit longer to add some compression within each layer and to accommodate for fraying strands of packing at each end. The size, length, and quantity of each piece can be found in the relevant Table. Each layer shall alternate between both the packing width pieces and the position of the smaller end pieces, as shown in Figure 12. Smaller end pieces will always be the piece to deform into remaining cavity.

Note: ensure body O-ring remains protruding from packing box after installation of packing.

2. Method of installing packing is shown in Figure 13. Place one end of packing to side of packing box. The other end should touch other packing pieces once installation of packing commences.

3. Start at the hump of each packing piece and pack the packing with a packing tool, as shown in Figure 14. Once the pieces are together to form the first layer, prepacking with a packing tool is required to fill in any gaps that can or cannot be seen. Each layer will require prepacking.

Note: do not let packing pieces to twist during installation.

4. Alternate packing layers, as shown in Figures 12 and 15.

5. If packed properly, the smaller pieces should fill in the cavity. Each layer of end pieces should be stacked in a specific way so that a piece of packing is sitting on top of a split line from the previous layer, as shown in Figure 16.To get the smaller pieces to fill in the cavity, opposite sides will have to be compressed to obtain an elongated smaller piece.

Note: not all sizes have smaller end pieces; some will have equal size end pieces.

6. Install packing gland with studs, Bellville Washers, and nuts as shown in Figure 17. For initial tightening of packing gland, tighten packing gland to achieve a compression between 0.125-0.375”. Use Loctite 262 (Red) on studs to secure in body.

Note: ensure each stack is facing the opposite direction and the final stack is cupped downward before adding the nut.

7. Tension must be placed on the nut to prevent the nut from backing out. First stack starts on the bottom, cupped down on the packing gland, as shown in Figure 18. Stacking method is provided on Table 2

CYLINDER OPERATED VALVES

Equipment orientationThe preferred orientation for optimum protection is with the cylinder in the vertical position. This position gives the best support to the cylinder rod and helps reduces the chance of a “flat spot” developing on the cylinder seals. An acceptable alternate position for valves with cylinder diameters of less than 6 inches (150 mm) is with the cylinder in the horizontal position.

Preparation for storageValves may be stored as shipped, provided the storage facility and equipment orientation instructions above are followed. If valve packaging is altered or removed for receiving inspection, repackage valve as originally received. Standard packaging materials cannot be considered sufficient for outdoor storage.

Cylinder storageThese cylinder storage instructions are not intended to replace the instructions of the specific cylinder manufacturer and are to be used as a guide only. If specific instructions are required, please contact our office. For storage of up to 3 years; Squirt a high quality grade of hydraulic oil or synthetic lubricant into

the cylinder ports and operate cylinder 6-12 times on a yearly basis. For storage 3-5 years; Lubricate as above. Additionally, extend cylinder rod until the valve is fully closed. Coat cylinder rod with high quality heavy grease or synthetic lubricant. Retract cylinder rod until valve is fully open, drawing lubricant into rod end of cylinder.
