Y Type Piston Check Valve
Product Description KOSEN Y Type Piston Check Valves is, also known as one-way valve, non-return valve and so on, is an automatic valve opening and closing itself by the force of flowing medium. And Forged check valve is mainly used for preventing the backflow of medium, the reversal of pump...
1. The valve disc is lifted and lowered. The connecting pipe connects the upper chamber with the valve outlet. When the disc is lifted and lowered, the impact and vibration are reduced, and the disc reaches the full stroke.
2. The valve body is Y-shaped, the resistance is small, the guide rib is overlaid with cemented carbide, the guide sleeve is stainless steel, the valve cover is flexible to operate.
3. pressure self tightening seal. Reliable sealing.
4. The sealing surface of disc and seat is made of cobalt-based alloy surfacing, which has high hardness, corrosion resistance, scratch resistance and durability.
