Non-variable Reducing Valves Operation 2010-12-02
Non-variable reducing valves, illustrated in Figure below, replace the adjusting spring and screw with a pre-pressurized dome over the diaphragm.
Standard Document for Instrument Relief Valves 2010-12-01
What is the intent of your relief device, is it intended for safety reasons or just pressure control?
Proportional flow valves 2010-12-01
Solenoid pneumatic 2/2 control valves to a proportional flow pneumatic valve. I was hoping to use a range of 0-5V to determine the flow rate of the valve.
Viscosity effect on Relief Valves 2010-12-01
The fluid is highly viscous (6,000-7,000 centipoise at 70F) and the flow is low (0.55 gpm). The fluid is 10% NaOH and 90% wetted cellulose in water and has a specific gravity of 1.12.
INSTALLING VALVES 2010-12-01
It does depend on the type of valve and actuator. If you tell me what kind I can get specific.
Pressure Reducing & Relief Valve 2010-11-30
There is a formal answer and a less formal answer.Informally, if your only purpose is to test the performance of a pump and not to protect from overpressure failure
