Assembly

Assemble the valve using the following procedure, referring to the

diagram as needed.

1. Place vent cowl (1) on the table with threaded portion lowermost.

2. Place valve plate (11) onto the seating surface of the vent cowl (1)

ensuring that the flat sealing surface is facing down (as shown in the

diagram) and in contact with the vent cowl seating surface.

3. Next place the diaphragm (4) onto the valve plate (11) so that the

center hole of the diaphragm is aligned with the stem of the valve

plate and the four cutouts on the outer edge of the diaphragm are

aligned with the threaded holes in the vent cowl (1).

4. Place the spring seat (3) on to the diaphragm (4) and the stem of

the valve plate (11).

5. Place spring (5) onto the stem of the valve plate (11) and on top of

the spring seat (3).

6. Place top cover (2) onto the top of the spring and, using a suitable

clamping device, bring the top cover and vent cowl (1) together,

ensuring that the diaphragm (4) is still aligned with the threaded holes

on the vent cowl. Check to ensure that the through holes in the top

cover are also aligned with the threaded holes in the vent cowl.

7. When the valve assembly is satisfactorily clamped together, take

the bottom half of the tamper proof cup seal (10) and place it on the

top cover flange (2) so that the hole in the cup seal is aligned with

one of the holes in the top cover flange.

8. Place a washer (6) on each of the four bolts (8) and thread each

bolt in turn into the valve assembly, as shown. Ensure that one of the

bolts passes through the tamper proof cup seal lower half (10) as

described in the step above.

9. Place the upper half of the tamper proof cup seal (9) onto the

assembled lower half (10) and press firmly to snap the two halves

together.

10. When all four bolts have been securely fastened, the valve

assembly may be unclamped and is now ready for testing.
