Types 95LD and 95HD

Type 95LD, the lower spring seat and diaphragm

plate (key 21) are threaded together and can be

removed as one unit.

3. If the unit has metal diaphragms,

a. Find the pusher post (key 30) and place on

a surface with the larger at surface down and

the thread stem up (metal diaphragm pusher

post has a recessed diameter in the bottom

surface). Then, nd one smaller composition

gasket (key 47) and t it over the threaded end

of the pusher post. Find and take one of the

diaphragm heads and slip it over the threaded

end of the pusher post with the chamfered

side of the diaphragm head toward the gasket.

Take a second gasket and place it over the

threaded end of the pusher post on top of the

diaphragm head.

b. Replace one of the two large diaphragm gaskets

(key 19) on the surface of the body that will

support the diaphragms. There will be two

diaphragms used per regulator, except for

Type 95LD, NPS 1/4 with 2 to 6 psi (0,14

to 0,41 bar) outlet setting which uses only one

metal diaphragm (the metal diaphragm is in

between two diaphragm gaskets). Another

diaphragm gasket will be placed on top of the

second metal diaphragm. The raised surfaces of

the metal diaphragms should be placed in the

unit so that they are facing toward the assembler

(toward the spring) except only when one metal

diaphragm is being used then the raised surface

should be facing down (towards the body).

See Figures 4 and 5 as references.

4. Set the diaphragm plate, lower spring seat, spring,

and upper spring seat back onto the diaphragm.

5. Place the spring case on the body. Tighten the

cap screws nger tight only.

6. To ensure proper slack in the diaphragm, apply

some spring force to the diaphragm by turning the

handwheel clockwise.

7. Finish tightening the cap screws.
