3 - PRESENTATION

The DN12 ERMETO valve with manual controls is specially designed to equip containers.

It is composed of an internal valve mounted on the container plate and of a 90� output valve placed on it.

The same controls are used to open and close the valve and check valve.

The DN12 ERMETO valve is used to fill and empty mobile containers.

5 - ASSEMBLY

5.1 – INTERNAL SAFETY CHECK VALVE (see diagram page 09)

The internal safety check valve is mounted on a specially fitted plate as shown on the diagram on page 10. This is fixed on the tank.

1. – Position the seal (2) (according to the fluid used), 43x33x1.5, in the plate groove.

2. – Grease the eight threaded holes

3. – Assemble the internal valve in the plate and attach it using the 8 hexagonal socket setscrews (1), tighten them up in crosswise order to a torque of 1.6 daN.m.

4. – In liquid phase, a pickup tube can be connected to the thread at the end of the internal check valve.

5. – Check the torques at least six hours after the operations.

5.2 –UPPER ANGLE VALVE: (see diagram page 09)

1. Place the second seal (2), 43x33x1.5, in the internal valve groove.

2. Position the valve on the internal check valve and screw the 4 x M14 nuts (3), complete with their washer, onto the studs. Tighten them in crosswise order to a torque of 5 daN.m.

4. Check the torque at least six hours after the operation.

6 – MAINTENANCE

- Check presence of grease in order to ensure the correct operation of the tap, by lifting the red cap above the rod casing.- If grease is required:

open the tap and add more Molykote MoS2 G-Rapid + grease, both inside the case and on the rod.

- Move the tap several times to allow the grease to penetrate into the control system.

7 - OPERATION

The DN 12 ERMETO valve is a manually controlled valve.

7.1 – MANUAL CONTROLS (see diagram above)

7.1.1 - OpeningCheck that the stem guide (3) is on the high position "F" (valve shut)Slowly unscrew the cap nut (1) with a 32 hexagonal wrenchConnect the valve outletUnscrew the stem bushing (2) until stem guide (3) is on the low position "O" (valve open)

with a 27 hexagonal wrench

7.1.2 - Closing

Screw the stem bushing (2) with a 27 hexagonal dynamometric wrench up to the high position "F" then apply a torque of 5 daN.m.

Important: only disconnect the valve after scavenging the nozzles and checking for nil residual pressure on the drainage line.

Screw back the cap nut (1) at a torque of 5 daN.m. with a 32 hexagonal wrench.

8 - LIMITATIONS AND PRECAUTIONS FOR USE

The following usage conditions are taken from Risk Analysis DT775 and are listed here because they are not explained in the paragraphs above.

● Risks linked to an impact following an accident:- The appliance is designed with minimal impact resistance (KV>27J).- The user should take care to fit the appliances on containers equipped with permanent or temporary protective devices.- The user should always check that the security cover is locked correctly before moving the container.

● Risks linked to corrosion caused by the environment of the appliance:- The user should check or create suitable protection for carbon steel appliances in relation to their environment.

● Risks linked to the action of the flame:- The appliance should not be in contact with the flame.

● Risks linked to the deterioration of seals with time (tap service life):- The user should ensure that the flange seals are replaced each time the appliance is used.- The user should ensure that the appliance is overhauled in accordance with the regulations in force.- The user should make sure that the appliance has been overhauled by Senior Aeorspace Ermeto or one of its appointed service agents before any change of fluid.- The user should check that the appliance is liquid-tight after every loading.

● Risks linked to stresses caused by the pipework:- The user should ensure that no stresses are caused when fitting equipment adjacent to the tap.

● Risks linked to dismantling the appliance under pressure:- The user must make sure that the appliance is not under pressure before doing any work on it.- The tap may only be dismantled by personnel qualified by Senior Aerospace Ermeto.

● Risks linked to modifications to the appliance:- No modification may be made to the appliance by the user (drilling, welding, grinding, etc.)

● Risks linked to sealing:- Have the appliance overhauled by Senior Aerospace Ermeto or one of its appointed service agents.

● Risks linked to the projection of products onto the appliance:- The user should make sure that the appliance is not placed close to a source of liquid or solid projections (sand blasting, high pressure washing, grinding, etc) that could damage it.



MANUAL


● Risks linked to unsatisfactory storage conditions:- The user should ensure that the appliance remains in its original packaging during storage.
