Pressure Safety Valve Testing Standards

This European Standard specifies dimensions, materials, and performance requirements (including methods of test) for pressure safety valves, of nominal sizes from DN 15 to DN 40, having working pressures from 0,1 MPa (1 bar) to 1,0 MPa (10 bar). Pressure...

This standard covers inspection, examination, supplementary examinations, and pressure test requirements for resilient-seated, nonmetallic-seated (e.g. ceramic), and metal-to-metal-seated valves of the gate, globe, plug, ball, check, and butterfly types. Resilient seats are...

SCOPE & LIMITATIONS Selection of a leakage class is not restricted as to valve design, but acceptable values for various commercially available designs are suggested for each class under Section 4. This standard applies to control valve seat leak production testing and cannot...

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...

Test site recommendations (Section 3): This section outlines the equipment needed for testing valves to determine the following: a. Valve flow coefficients (Cv). b. Pressure drop ratio factor (Xt). c. Gas-lift valve performance curves. Gas-lift valve...

This specification establishes the requirements for the manufacture, inspection and testing of a pneumatic solenoid controlled valve, designated as the Aero 2A Pneumatic Valve, suitable for controlling the operation of a 20MM pneumatic gun charging system operating at...

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...

This test standard utilizes the mathematical equations outlined in ANSI/ISA-75.01.01 (IEC 60534-2-1 Mod)-2007, Flow Equations for Sizing Control Valves, in providing a test procedure for obtaining the following: a) Valve flow coefficient, C (Cv, Kv) b) Liquid...

Purpose. This procedure describes the tests to determine the durability of ventilation valves (pressure regulator, check valve, bypass valve, etc.) in an engine ventilation system. Applicability. The engine ventilation system valve durability test is...

This EEMUA publication offers guidance on the application of the PED to the purchase of (a) block valves, check valves and control valves which may be considered as pressure accessories and (b) safety relief valves and such other valves which may be...

ABSTRACT This report presents the findings of a study for the Production Department of the American Petroleum Institute entitled, "Subsurface Safety Valve Research Study--Year 1". The purpose of the work is to define potential changes to API Specification 14A for Subsurface...

This standard describes the double check-valve backflow prevention assembly for potable water applications. The assembly shall be capable of withstanding a working water pressure of at least 150 psi (1,034 kPa) without damage to working parts or impairment of function and for...

ABSTRACT This report presents the findings and recommendations from the third year of an American Petroleum Institute (API) research study aimed at updating the Specification 14A Verification Test Procedure for surface-controlled subsurface safety valves (SCSSV). Specification...

This standard specifies the requirements for comparative testing of valve stem packing for process applications where fugitive emissions are a consideration. Packing(s) shall be suitable for use at service temperatures -29 °C to 538 °C (-20 °F to 1000 °F). Factors affecting fugitive...
