Testing — Double Check Valve Assembly

Test Check Valve No. 1

Step 1: Ensure shutoff #1 is open, shutoff #2 is closed.

Step 2: Connect high side hose to test cock #3, low side to test cock #2

and open both test cock #2 and test cock #3.

Step 3: Open valve C, then open A to bleed air from the high side. Close

valve A, then open B to bleed low side. Close valve B.

Step 4: Connect vent hose loosely to test cock #1. Open valve A to vent air

from vent hose. Tighten vent hose at test cock #1, open test cock

#1.

Step 5: Close shutoff #1. Slowly loosen hose at test cock #2 until differen-

tial gauge rises to 2psi and retighten hose. If the differential reading

does not decrease, record check valves as "tight".

Test Check Valve No. 2

Step 1: Move the high side hose to test cock #4, low side to test cock #3

and open both test cock #3 and test cock #4. Remove vent hose

from test cock #1, open shutoff #1.

Step 2: Open valve C, then open valve A to bleed air from the high side.

Close valve A, then open valve B to bleed low side. Close valve B.

Step 3: Connect vent hose loosely to test cock #1. Open valve A to vent

air from the vent hose. Tighten vent hose at test cock #1, open test

cock #1.

Step 4: Close shutoff #1, then slowly loosen hose at test cock #3 until

differential gauge rises to 2psi and retighten hose. If the differential

reading does not decrease, record check as tight. Remove all hoses

and restore valve to original working condition.

NOTICE

The assembly will fail both the first and second check valve tests above, if

shutoff #2 leaks excessively. To test for a leaky #2 shutoff, use the following

procedure.

Test for Leaky No. 2 Shutoff

Step 1: Connect the high side to test cock #1, low side to test cock #4.

Open test cock #1 and test cock #4. Close shutoffs #1 and #2.

Step 2: Close valve C. Open valve A, then open valve B

hose at test cock #4 to remove air. Retighten hose.

Step 3: If the differential gauge rises above 0, there is excessive leakage at

shutoff #2 and it must be replaced to test the assembly.
