7.2.1.
Installation of Diaphragm
Note:
Before removing any parts from the diaphragm valve, trip the impact valve,
and shut OFF the submersible pump for the product in question.
1. Remove the four (4) bolts and the diaphragm cover.
2. Remove all existing parts and discard them. With the exception of the center
section and cover, which must be reused. Take note of the position of the parts
as they are removed so the new parts can be installed the same way.
3. The perforated back up plate must be installed first, with the dished center
hole located around the valve seat and the higher outside diameter level
with the valve body. Care must be taken during assembly to be sure the
plate has not slipped and become pinched between the diaphragm and the
body. Be sure to install the red tinted back up plate in diaphragm castings
with three tabs around the outer perimeter of the diaphragm bore; install
the plain plate in castings with four tabs (see the installation instructions
included with the diaphragm kit for further information).
4. The spring must be seated squarely in the spring cup so that it will stay in
place when the valve plate is installed. The relief valve must enter the end
of the spring without dislodging the spring from the spring cup.
5. The notched gasket must be between the center section and cover, and the
gasket with the hole between the center section and the body.
6. Hand tighten the four (4) bolts, using a criss-cross pattern until the bolt heads
just contact the valve cover. Continue this pattern increasing torque until all
bolts are fastened to a torque of 9-11 ft.-lbs. This torque must not be exceeded
in order to keep the gaskets from deforming and covering the ports.
7. Check operation and inspect for leaks.
