Design features:

Channel, flow area is big, small loss of valve

Double buffer design, open, close the small impact

Valve plate rolling motion is small, the impact velocity of small, long service life

Strong buffer spring, can resist oil viscosity

Antifouling treatment, liquid-strike, resistance, oil resistance viscous impurities, is not easy to accumulate, good reliability

Applicable conditions:

In the high-pressure condition

In low speed, speed <1000rpm

Oil and no oil of different design
