Questions buyers ask
What pressure, flow and temperature is it rated for?
Maximum working pressure is 250 psig. Flow capacity ranges from a minimum Cv of 18.9 to a maximum Cv of 70.1 with a 3" trim size and flow coefficient of 0.79. Temperature rating is not specified in the listing—ask the seller for the temperature range and whether seat material limits apply.
What gases is it compatible with, and has it been oxygen cleaned?
The valve is rated for both liquid and gas process fluids. The listing does not specify oxygen cleaning status or previous service history—contact the seller to confirm what fluids it has handled and whether oxygen service preparation is required for your application.
What materials are the wetted parts?
Body material is cast ductile iron with linear trim. The listing does not specify trim material, seat material, or seal materials—ask the seller for complete wetted parts material list, particularly if corrosive service or NACE MR0175 compliance is required.
What should I inspect before putting it into service?
Verify Class VI shutoff with a seat leakage test, inspect trim and seat surfaces for erosion or damage, and confirm actuator spring response at the specified 10 psig crack and 35 psig full open settings. Check body casting and flanges for cracks or corrosion, verify gasket seating surfaces are clean and undamaged, and bench-test the pneumatic actuator through full stroke to confirm fail-closed operation.
