Proportional Control Valve Standards

Production acceptance and type (or qualification) tests. Applicable to 2-, 3- and 4-way flow control valves and to 2-way pressure control valves.

This part of ISO 10041 specifies the characteristics of electro-pneumatic continuous flow control valves that are to be included in the supplier's literature. According to ISO 5598, continuous control valves include: - electrically modulated pneumatic proportional...

This part of ISO 10094 specifies which characteristics of electro-pneumatic continuous pressure control valves are to be included in the supplier's literature. In accordance with ISO 5598, these control valves include - electrically modulated pneumatic...

Scope and field of application This International Standard specifies methods for testing hydraulic valves which are used for the control of flow or pressure in a circuit in order to determine their steady-state and dynamic performance. Requirements for test installations and...

This standard includes a standardized procedure for defining, measuring and reporting the response time of hydraulic solenoid operated directional control valves with minimum influence from the system. Valves included are electrically controlled, either directly or with...

Efficiency is a crucial concern across computing systems, from the edge to the cloud. Paradoxically, even as the latencies of bottleneck components such as storage and networks have dropped by up to four orders of magnitude, software path lengths have progressively increased due to overhead from...

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 characteristics...

This specification is applicable to all valve springs, ready for installation, which are manufactured from alloy spring steel. Mission / Theme. Not applicable. Classification. Not applicable. Note: Nothing in the specification, however, supersedes applicable laws and regulations unless a...

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 specification covers an outlet valve which has a plastic valve seat, cover and a rubber disk. The valve is a component of a chemical protective mask (see 6.1).

This part of ISO 23551 specifies safety, constructional and performance requirements and testing of automatic and semi-automatic shut-off valves for gas burners, gas appliances and appliances of similar use. It applies to - normally closed valves, - valves being mounted...

This specification establishes the requirements for the manufacture and acceptance of the 3-way solenoid valve (also known as the Mode Selector Valve (MSV)), used in the Fire Control System for the M109A6 Self-Propelled Howitzer (SPH) (see 6.1).
