professional 400LPM pilot check valve

Sj technology is a professional manufacturer of hydraulic control valves with 40lpm-400lpm flow rate, hydraulic gear pumps with g1,g2,g3 series, hydraulic power units, pilot check valve and we design the hydraulic system for your machinery too.
Parker’s p.o. check valve’s allow flows up to 226 lpm (60 gpm) and pressure up to 350 bar (5,000 psi). return flow can be enable by an external pilot supply, which
Some specific pilot pressure is needed to open the check. if the required pilot pressure is 33% of load pressure, the valve is designated a 3:1 pilot-operated check valve. when a pilot-operated check valve is used for the application shown in fig. 7.10, it is typical to have it open with as small a pilot pressure as possible—say a 5:1 valve.
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 higher than the cylinder internal ratio “φ”, where “φ” = cylinder full bore area / cylinder annular area. in this case,

Professional 400lpm hydraulic mobile valve – uae dansk co ... Product description. directional seated valves are a type of directional valve. as ball valves they have zero leakage in the closed state. the directional seated valve type g, wg, h, p, k, t and d is available as a 2/2, 3/2, 4/2, 3/3 and 4/3 directional seated valve with different actuation types.
