Flow is controlled by either throttling or diverting it. Throttling involves reducing orifice size until all of the flow cannot pass through the orifice; bypassing involves routing part of the flow ...

New ZL Series proportional flow control valves from HydraForce Inc. (Lincolnshire, IL) are internally pressure-compensated and operate in two directions. "The valves provide identical flow vs current ...

This paper presents the development of a physics-based model of a proportional directional valve with the aim of describing its dynamic behavior while accounting for the influence of friction forces ...

The compact design of the VSNG6 solenoid-operated directional-control valves features reduced solenoid dimensions, making the valves suitable for mini-power pack, mobile, and agricultural applications ...

Incorrect valve selection and poor fluid dynamics lead to catastrophic pressure blowouts, destroyed pump systems, and severe ...

Choked flow in control valves is a subject of serious concern for industrial users. The term is usually associated with destructive process conditions that can damage valve internals or expose ...
