SERIES

INSTALLATION / OPERATION / MAINTENANCE

Note 1: flanged gasket

must bridge this joint

for pressure seal

Installed with name plate here

OPERATION:

Cla-Val Silent Check Valves operate automatically, to open...

when pump flow starts and close silently ...when pump flow

stops.

INSTALLATION:

Silent Check Valves, Wafer and Globe style must be

installed between flat faced iron or steel flanges per ANSI

B16.5 or Awwa 207, utilizing a full faced gasket to bridge the

joint between the seat O.D. (2) and the body (1) flange face.

In this manner a pressure seal at this joint is made (see

Note 1). Install the valve so that the nameplate data is plain-

ly read and the flow arrow points in the flow direction.

MAINTENANCE:

Cla-Val Silent Check Valves are ruggedly designed for years of trouble-free

service. Therefore, regular maintenance is not required. However, during

initial start-up period the following problems may surface (due to mis-application)

that can be easily resolved:

A. No Flow thru Valve:

1. Observe that the flow arrow name plate, on the

valve body, is pointing in the direction of flow.

2. Check that the down stream shut-off valve is full open.

B. Valve Chatters:

1. Confirm that the flow velocity is a minimum 3’/Sec.

2. Check that there is a minimum of 3 diameters of

straight pipe installed up stream of the silent check valve.

C. Valve Leakage:

1. Confirm a full face gasket is installed per Note 1.
