New STV Test & Blocking Valve

The Nicholson Steam Trap Division of Spence Engineering Company Inc., Walden, New York, has announced its new STV Combination Test & Blocking Valve, which eliminates the need for two valves and multiple fittings to check steam trap operation. This specially designed valve provides both functions in one body, reducing cost, labour and potential for leaks. The STV can be used to sample fluids or gases from process lines. The Nicholson STV is installed on the downstream side of the steam trap. During operation, it is in open position with unrestricted flow through the trap into the condensate return system. One-quarter turn blocks flow and directs trap discharge to atmosphere for visual inspection.
