The ultraminiature PCFCD-1N1 pressure-compensated flow-control valve, with a low-friction diaphragm, is designed to maintain a constant flow rate, regardless of variations. The ultraminiature ...

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

This paper describes a new principle for pilot-operated hydraulic relief valves. The new, patented feature enables pressure relief valves to not only limit a pressure differential, but also to limit ...
