The CVP21 Series of M22X1.5 threaded cartridge type hydraulic check valve has the good operation characteristics:
1.Keep up the pressure. The directional valve has a slide leakage gap, only a short time to maintain pressure, when maintain pressure requirements, which can be coupled with one-way valve in the oil circuit, using the poppet valve is closed tightly, so that long pressure maintenance can be obtained.
2.For supporting the cylinder, in the vertical hydraulic cylinder poppet valves and pipes due to leakage in the piston and piston abundance if the heavy may cause piston and piston rod down. The cartridge type hydraulic check valve chamber connected to the circuit under the hydraulic cylinder, hydraulic cylinder can be preventing such activities as part of the piston and slide down.
3.For hydraulic cylinder lock. When the directional valve is in the meddle position, the hydraulic check cartridge valve is closed, the two can be tightly closed chamber of the oil hydraulic cylinder, when the piston can't move because of external force generated.
Any custom design ofhydraulic check cartridge valve are available, we will design, choose the suitable materials, checking proper working characteristics, testing working operation and service life for our regular customers, please contact us for more details.
