Questions buyers ask
What pressure, flow and temperature is it rated for?
This unit is rated for 150 ANSI pressure. Flow capacity (Cv) and temperature rating are not stated in the listing—ask the seller for the nameplate data or test certificate that would show the Cv value and maximum temperature limit. Diaphragm control valves in this class typically handle temperatures up to 200-300°F depending on diaphragm material, with Cv values for 1-inch bodies generally ranging from 3 to 12.
What materials are the wetted parts?
The body is 316 stainless steel. The listing does not specify diaphragm material, trim material, or seat material—these are critical for chemical compatibility and should be confirmed with the seller before purchase.
What should I inspect before putting it into service?
The seller states this unit needs reconfiguration before use. Inspect the diaphragm for cracks, hardening, or permeation damage; check the seat and plug for erosion or scoring; verify actuator spring integrity and diaphragm casing bolt torque; and stroke-test the valve to confirm smooth travel and proper seating. Bench-test the valve with your controller to verify linearity and confirm that the close action matches your application requirement—reversing the action may require actuator disassembly or positioner reconfiguration.
