SAE AS1225 - Oxygen System Fill/Check Valve
December 1, 1997 - SAE

This SAE Aerospace Standard (AS) defines minimum standards of design, construction, and performance for two types of permanently installed, high pressure 12,800 kPa (1850 psig) and 13,800 kPa (2000 psig) oxygen system cylinder fill valves used in commercial aircraft. Refer to Purchaser's...

ISA RP75.23 - Considerations for Evaluating Control Valve Cavitation
June 2, 1995 - ISA

This recommended practice is intended for control valves used in the control of process fluids and is not intended to apply to fluid power components. The reader and user should be familiar with fluid mechanics fundamentals and ISA standards ANSI/ISA S75.01 and ANSI/ISA S75.02...

FMAPPROVAL 7400 - Liquid and Gas Safety Shutoff Valves
November 1, 2016 - FM

This standard sets performance requirements for liquid and gas safety shutoff valves, fire safe (class 7440) and non-fire safe (Class 7400), used in the supply lines of commercial and industrial burners as well as in ignitable liquid piping systems. Safety shutoff valves are intended...

IEC 60534-8-4 - Industrial-process control valves – Part 8-4: Noise considerations – Prediction of noise generated by hydrodynamic flow
September 1, 2015 - IEC

This part of IEC 60534 establishes a method to predict the noise generated in a control valve by liquid flow and the resulting noise level measured downstream of the valve and outside of the pipe. The noise may be generated both by normal turbulence and by liquid...
