The ball valve 1 in size SS316 as 150# rating. On the valve body 5000psi rating is embossed.Are the two pressure equivalent?

Is a CS body valve with 10mm corrosion allowance readily available for all pressure classes or if they need to be specially manufacturered? Or is the 10m corrosion allowance OTT (over the top)

A line which we want to shut off the steam to has no steam trap on it. The line runs into a sump, where it just flows out of the pipe. The valve is by the main steam header.

A relief valve set for 1250 psi on a system with a positive displacement pump (2500 rpm) sees pressure spikes of 1275 psi every 1.5 seconds. However, the RV does not lift.

1 ¼” ball valve and possibly 2 each of a 3” ball valve or gate valve that have metal seats and meets NACE MR0175 SPECIFICATION FOR SOUR GAS SERVICE.

For a valve test bench we are looking for ball valves to be installed in the filling pipes with as big as possible open flow path.

1" CS (150# class - DP: 1900kPa) instrument gas strainer need to be replaced, what would be the best option of strainers (preferably flange-flange type) available?

oes anyone have a definitive reference for the required tap depth for a 3/8" NPT port.I understand from reading on here the tap depth is not usually called out.
