Powercheck Valve

100-03

DESCRIPTION

This manual contains information for installation, operation and main-

tenance of the Cla-Val 100-03 Powercheck, an automatic valve

designed for use where independent operating pressure is desired,or

when line fluid is unsuitable as an operating medium.

This valve is a hydraulically operated, diaphragm type, globe or angle

pattern valve. It is single seated and incorporates into its design two

operating chambers sealed from one another by a flexible synthetic

rubber diaphragm. Pressure applied to the upper chamber closes the

valve; when applied to the lower chamber, it opens the valve.

With proper pilot controls, the valve can be held in any intermediate

position between fully open and tightly closed unless a static condition

or pressure reversal occurs, in which case the valve closes to prevent

return flow regardless of the diaphragm position.

INSTALLATION

Allow sufficient room around the valve assembly to make adjustments

and for disassembly.

NOTE: BEFORE THE VALVE IS INSTALLED, PIPE LINES SHOULD

BE FLUSHED OF ALL CHIPS, SCALE AND FOREIGN MATTER.

It is recommended that gate or block valves be installed on both the

upstream and downstream sides of the 100-03 to facilitate isolating

the valve for preventative maintenance.

Place the valve in the line with flow through the valve in the direction

indicated on the inlet name plate or by flow arrows and with the cover

"UP" Other positions are not acceptable due to the check feature.

When a pilot control system is installed on the Powercheck Valve, use

care to prevent damage. If it is necessary to remove fittings or com-

ponents, be sure they are kept clean and replaced in the exact order

of removal.

After the valve is installed and the system is first pressurized, vent air

from the cover chamber and tubing by loosening fittings at all high

points.

TROUBLE SHOOTING

The following trouble shooting information deals strictly with

the Powercheck Valve; however some "possible causes" will

refer to components that may exist in the variety of control

systems available for the valve. All trouble shooting is possi-

ble without removing the valve from the line.

SERVICE SUGGESTIONS

(Service Suggestions Chart)

CAUTION: Extreme care should be taken when servicing the

valve. Gate or line block valves must be closed upstream and

downstream of the valve before starting disassembly. When

there are no block or gate valves to isolate the Powercheck

Valve it should be realized that the valve cannot be serviced

under pressure. Steps must be taken to remedy this situation

before proceeding.

Check Action

When a static condition or pressure

rever-

sal occurs, the split stem design allows the

valve to instantly check closed. Return flow

is prevented regardless of the diaphragm's

position.

Principle of Operation

Tight Closing Operation

When pressure below the diaphragm is

relieved and operating pressure is

applied to the cover chamber, the valve

closes drip-tight.

Full Open Operation

When operating pressure below the

diaphragm is applied and pressure is

relieved from the cover chamber, the

valve is held open allowing full flow.
