The original API 622 draft was intended to be a test for the packing, whereas ISO 15848 is for the whole valve.

An influent 60" diameter emergency force main that operates at 28 psi for a wastewater treatment plant. 40 psi is the specified operating pressure.

An sluice gate is operating on a pipe with maximum pressures due to an upstream pump of 50 psi and discharges to an open top tank of 10ft depth.

Replacing 2 PRV's(3/4" by 1 1/2" Stainless Steel) on Jet A-1 fuel storage tank inlet 8" and outlet 5" pipeline.

We are specifying 84" x 144" sluice gates in one of our projects and we expect very high torque and thrust required for the actuator to pull up the gate under a head of 40ft water.

For air piping application after the air receiver tank, 2" ss check valves will be installed. I think we are going to select UN3 type from CHECKALL VALVES manufacturer.

The differencce between wegde gate valves and slab gate valves.The basic difference, as you can see now, is one seals against leakage using a force applied to a wedging action against the valve in a d

Noise is generated by mass flow rate and velocity. Certain valves have greater acoustical efficiency (the ability to turn energy into noise) than others.
