The assembly shall include two tightly closing shutoff valves before and after the valve and test cocks .

The valve is offered with either a soft or metal seal, providing capability for enhanced shutoff.

Precision machined tilting disc and seat for tight shutoff in reverse flow direction.

Hazard is if the main shutoff valve is "stuck" , these valves may add another level of isolation.

The perimeter seat design gives bubble tight shutoff in either direction.

Slowly open upstream shutoff and allow the backflow preventer to fill slowly.

CAUTION: WHEN GAS SHUTOFF OPERATES, IT SHUTS OFF GAS SUPPLY TO BOTH MAIN BURNER AND PILOT.

The oil productivity raises gradually after a water shutoff job with RPM conducted.

Install a shutoff valve upstream of the regulator.

Close the shutoff valve upstream of the regulator.

When we reach to ATM machine of Bank of China, we noticed that the biggest national bank on three days shutoff for computer system upgrade.

Prevents reverse flow where leak-tight shutoff is required.

Globe valves are used where throttling or both throttling and shutoff are required.

NOTE : The assembly will fail both the first and second check valve tests above, if shutoff No. 2 leaks excessively.

unlimited bottom of pipe, shutoff pressure on packer.

No downstream shutoff valves are allowed.

Slightly open shutoff valve No. 1 and allow water to fill the tube to the top then close No. 1 shutoff.

Remove all test equipment and open No. 2 shutoff valve of the device.

if the differential gauge rises above 0 , there is excessive leakage at shutoff # 2 and it must be replaced to test the assembly.

The termination of rocket OR jet - engine operation because of fuel exhaustion OR shutoff.

The electric current has been shutoff.

The water shutoff curtain water shutoff rate can achieveabove 80%.

The test cock is on the inlet side of the shutoff valve.

In addition, the Perma-Cyl seriesfill shutoff device assures a complete and safe fill each time.

Attach hoses as shown. Bleed air from kit, close No. 2 shutoff.

Purpose: To test shutoff valve No. 2 for tightness.

China Oilfield chemical water shutoff technology from the 20th century from the 50's application in the field has been 50 years.

The 96330 is used most effectively for safety shutoff or operating valves in manifold lines.

Close shutoff valve No. 2 then shut off valve No. 1 on test assembly.

Close #2 shutoff valve.

The burner body (4) is spatially separated from the gas shutoff valve (2).

Close shutoff valve No. 2 then shutoff valve No. 1.

Close shutoff valves No. 1 and No. 2.
