Subsea oil and gas production subjects industrial instrumentation to some of the harshest operating conditions. Valves — particularly those used for isolation and flow control — bear the brunt of ...

The new handheld control valve tester simplifies testing with dedicated tests that perform a quick health check to provide good/marginal/bad results Control valve testing has meant using complicated ...

Feedwater control valves play a critical role in boiler operation. One important parameter of their design is the pressure drop at the rated condition as well as off-design conditions. However, ...
