What does a Triple Air-Valve Tester do?
Operates equipment to test various types of triple air valves for conformance to federal and company safety standards: Mounts valve on test frame and connects air supply hoses to valve, using portable power wrench. Moves test panel control levers singly or in combination to open or block air passages into different chambers of valve. Turns lever to inject air into unblocked chambers, reads gauges to determine specified pressure differentials, and to detect leaks, weak springs, and poor fits. Applies soapy water to valve with brush to pinpoint air leaks. Replaces defective parts. Rejects valves that do not meet specifications.
