Feature of CV Self-Sealing Valve

• Self-sealing: when this valve is disconnected from either side,it can seal and stop the flow of gas.

• Can withstand repeated usage

• Can be used on outdoor switchgear

• Can connect SF6 gas filling and vacuum pumping devices

• Can connect SF6 gas recovery truck
