This European Standard specifies dimensions, materials and performance requirements (including methods of test) for combined temperature and pressure relief valves, of nominal sizes from DN 15 to DN 40, having working pressures from 0,1 MPa (1 bar) to 1,0 MPa (10...
This standard includes: ⎯ standard methods for testing the performance characteristics of hydraulic pressure relief valves; ⎯ a uniform method for presenting the test data; ⎯ standardized information for conducting comparative tests. This standard is...
This specification establishes the requirements for hydraulic pressure relief valves.
This specification covers the requirements for one type of low-pressure relief valve for use in pressurized shipping containers.
This specification covers one type of in-line hydraulic pressure relief valve used in a military combat vehicle to control system differential pressure at a predetermined level (see 6.1).
This standard covers inspection, examination, supplementary examinations, and pressure test requirements for resilient-seated, nonmetallic-seated (e.g. ceramic), and metal-to-metal-seate
This Recommended Practice (RP) provides general guidance on valve selection for the hydrocarbon processing industry (HPI), which includes refineries and petrochemical, chemical, and liquefied natural gas (LNG) plants and their various associated processes. Selection guidance is provided for...
This SAE Standard applies to hydraulic directional control valves as applied to self-propelled work machines referenced in SAE J1116. It describes a laboratory test procedure for evaluating: a Flow versus pressure drop b Leakage rate c Operating effort d Metering...
