External Exhaust Valve: G3-M/G3-ME


External Exhaust Valve is most effective to prevent leak testers from contamination when testing parts contain water and/or oil inside.

Edge & Function


●When small amounts of water, oil, or similar substances are remained inside tested part or when it is used in a testing device which is used in combination with water-dunking, such foreign matter could contaminate the tester when air is exhausted and cause malfunction.
Such malfunction can be setting up this exhaust valve unit close to WORK.

●It uses a special air-operated valve with a structure which is resistant also to solid waste.

●The movement of the exhaust valve can be controlled by the tester body.
