Saunders A Type Diaphragm ValvesValve Benefits for Corrosive and Abrasive Applications
6 Crane Process Flow Technologies
Our Saunders A Type diaphragm valves have been developed to handle a wider range of fluids and gases than any other valve type. A wide choice is available for materials, methods of operation and body end connections –to satisfy the needs of most corrosive and abrasive applications.
Pocketless design for contamination free performance and smooth flow characteristics. Linear operation ensuresvalve does not induce damaging pressure surges or static charges.
Three part design allows maintenance and actuator retrofittingwithout removing thevalve from the pipeline.Overall this results inlower cost of ownershipcompared to other valve types.
On pressure and vacuum, Saunders diaphragm valves operate and close 100% leaktight even after thousands of operations. This feature reduces processing and handling costs, by eliminating emissions normally associated with conventional valve designs.
All working parts of the valves are isolated from the line media and positive closure is obtained even on frequent cycling or with entrained particulates in the line unlike quarter turn ball and butterfly valves. Throttling and control characteristics are enhanced by a streamlined flow path that is cavity free and provides excellent flow control capabilities.
Extended life, reliability, safety and ease of use, combined with an essentiallysimple design, results in low maintenance for minimum running costs.

Saunders WFB Type ValvesFor Marine and Firefighting Applications
20 Crane Process Flow Technologies
The WFB valve is a weir type diaphragmvalve developed to overcome conventionalvalve problems on fire fighting, tank cleaningand wash-down on land or sea, whereverguaranteed valve operation is needed.
There are no second chances with a defectivefire hydrant valve. Saunders WFB modelprovides dependable operation when it matters– even after years of non-use.
This highly specialised fire hydrant valve hasbeen tested and approved by the world’sleading safety agencies. Similar in design andoperation to the widely used A Type, it has theadded benefit of a certified chlorosulphonatedpolyethylene base fire resistant diaphragm. TheWFB valve is available in SG iron or gunmetalproviding high mechanical strength. This meansthat they provide greater resistance toaccidental impact. Gunmetal resists corrosionon the more demanding applications.

Saunders KB Type Diaphragm ValvesStraight Through Bores
22 Crane Process Flow Technologies
Saunders full bore KB type diaphragm valves, with their smooth non-turbulent body design haveproved to be outstanding in resisting the erosiveeffects of corrosive and corrosive/abrasive linemedia. In addition, the full bore concept isdesigned for minimum flow resistance whilstallowing rodding out and easy cleaning.
Low pressure drop and high flow characterise theefficiency of operation of these valves. The flexiblediaphragm ensures consistent leak tightness evenwhen solids, powders and dry media are present. Valve blockage and wear due to slurry build up on the valve internals are significantly reduced by thestraight through design.
In addition to the range of unlined screwed andflanged bodies, rubber linings and glass coatings are available for the more exacting corrosive andabrasive applications to a maximum working pressure of 10 bar.
Features Benefits
Straight through body, high flow No obstruction, low pressure drop
Flexible closure even with solids present Leaktight by design
Only two wetted parts Better resistance to corrosion/abrasion and longer life
Specially developed linings and diaphragms available Minimal maintenance
Valve flow
Smooth bore straight through body gives high flow performance with minimum turbulence, while giving 100% leaktight closure.
Lubrication
Bonnet assembly lubricated for long life. Needs no further grease. The indicator lip seal stopsthe ingress of dust, dirt and atmosphericcontaminates.
Ease of maintenance
Three part design allows maintenance andactuator retrofitting without removing the valvebody from the pipeline. Extended life, reliabilityand safety, combined with essentially simpledesign, result in low maintenance and low costof ownership.
Valve usable in any position
The KB valve can be installed in any positionwithout affecting its operation. We recommend six times pipe diameter from pump or bend.
Saunders KB Type Design Features Contribute to low pressure drop high flowcapability and long valve life

Pneumatic Valve ActuationCompact Actuators that Provide Reliable Remote Control
30 Crane Process Flow Technologies
Saunders EC and SSC Pneumatic Actuators facilitate remote operation ofthe valve, as an integral part of a control system. Both are compactpiston style actuators with excellent chemical and temperature resistance.
The versatile and robust design derived from the use of high technologymaterials of construction, results in an actuator suitable for a wide rangeof process industry applications.

SSC
With the same flexibility asthe EC Actuator, the SSChas been manufacturedwith a 316C12 stainlesssteel investment casthousing. Suitable for bothaseptic and industrialapplications the SSC hasexcellent resistance toboth chemical and steam duties.
Size range DN8 – DN50
All three operationmodes, double acting,spring to close andspring to open featurethe same physicaldimensions for a givenvalve size. This providesuniform compactenvelope dimensions andoutstanding economicbenefits particularly forspring return failsafeactuation.
Field conversion ofmanual valves to poweractuation is readilyachieved ‘in-line’ withoutspecial tools ormodification.

Pneumatic Valve ActuationEV and ES Actuators
32 Crane Process Flow Technologies
ES spring close
EV spring close
The EV/ES actuator offers efficient mechanical/pneumatic control ofthe diaphragm, allowing remote and automated operation.
Saunders EV/ES actuators are designed with close coupled bonnetassemblies and have complete flexibility of performance. Several differentactuator models may be provided for each valve size to suit different lineand operating pressures. The range allows valve closure against themaximum valve working pressures and can be successfully used formodulating control duties in addition to more normal isolation functions.
Failsafe closing actuators are fully adjustable, i.e. spring compression canbe externally adjusted to provide optimum diaphragm forces and henceprovide extremely long diaphragm life in service.
Many accessory options are available which include solenoid valves,remote indication devices (switches or sensors) to suit environmentalconditions such as hazardous services. Limit stops and positioners andmany other devices may be offered to allow usage within particularcontrol systems. EV/ES actuators are provided with a tough polyester coating which gives maximum durability, even in exposed locations.
Saunders diaphragm valves offerexcellent control capabilities within abroad range of pressure, flow or levelcontrol applications.
Rangeability (ratio of maximum flow vs. minimumcontrol flow) of Saunders weir type valves is 35:1extending beyond the range of most processand service control systems.
The positive shut-off characteristics of the valvecan, in many instances, eliminate the need forindependent block valves, a major component inthe piping system cost.
The inherent flow characteristics illustratedshows linearity up to 60% of travel (80% of flow).
The chart illustrates installed characteristicsaffected by the dynamic friction loss for theremainder of the piping system. Equal %characteristics can be obtained through the use of characterised positioners.
Pressure recovery factor = 0.7.
