Pilot Valves | Parker NA

Parker offers a large collection of pilot-operated (PO) check valves, which are check valves that can be opened by an external pilot pressure. There are two types of pilot operated check valves: threaded cartridge style and pilot piston style. These pilot valves work best when used in conjunction with a control valve that vents the valve ports to tank when centered.

PDF PILOT OPERATED CHECK VALVES - Bosch RexrothPDF

Pilot operated check valve modules are available in SINGLE ACTING and DOUBLE ACTING version: in both cases, one of their basic parameters is the Pilot Ratio "R", defined as Pilot piston area / Check valve seat area. When a pilot operated check controls the cylinder annular chamber it must always have a Pilot Ratio "R" significantly

What is Pilot Valve? Working Principle & Types (Complete Guide

Pilot valves are high-flow control valves for a system. The pressurized fluids mostly move the pilot-operated valves. When the set pressure is achieved, the valve opens and the pressure is released. The flow directing element of the valve changes when pressured fluid meets the valve piston.

Pilot-Operated Check Valve - jp.mathworks.com

A test circuit built to check the characteristics of a pilot-operated check valve. The valve is loaded with three ideal pressure sources, two of which create pressure differential across the main flow line, while the third applies pressure to the pilot inlet X. The pilot pressure allows flow through the valve even if the main pressure
