Design Advantage: 1.Multimedia Grooves ——— Large flow area, low loss of the  valve 2. The double damping design ——— low impact when opening and closing 3. The tilt motion of the valve is low ——— low impact speed, long life 4. Strong buffer spring ——— resistance to oil viscosity 5. Soil Resistance ———— Resistance to liquid and impurities and oil viscosity, high reliability   Suitable Area: 1.The condition of medium-high pressure 2. Medium-low speed condition, rotation rate < 1000 rpm 3. Different designs for Oil and  Non-Oil condition
