LYV® PSB Swing Check Valve Product Overview
PSB Swing Check Valve come in three bonnet designs. A bolt type valve cover, according to this design form of the valve, the valve body and the valve cover with bolts and nuts connected, winding gasket (316 clamp flexible graphite manufacturing) seal. Customers have special requirements can also use metal ring connection. The second design form is the valve cover, according to this design form of the valve, the valve body and the valve cover with thread connection, full welding seal. Penetration welding can also be used when customers have special requirements. The third is the pressure self-tightening valve cover, according to the design of the valve, the valve body and the valve cover with thread connection, internal pressure self-sealing ring. Check valves come in three different designs. They are lift check valves, ball check valves and swing check valves.

LYV® Self sealing swing check valve Feature And Application
1. Product design and manufacturing according to GB12236 design standards, reasonable structure, reliable sealing, beautiful appearance.
2. The sealing surface of the valve disc and seat is made of slite cobalt-based hard alloy surfacing, with wear resistance, high temperature resistance, good abrasion resistance and long service life.
3. Various pipe flange standards and flange sealing surface types can be used to meet various engineering needs and user requirements.
4. Valve body material variety complete, packing, gasket according to the actual conditions or user requirements reasonable selection, can be applied to a variety of pressure, temperature and medium conditions.
5. The disc rotates around the pin outside the seat to reduce the violent impact during closing.
6. The pin shaft is connected with the valve disc with built-in pin structure, which reduces the leakage point and makes the use more reliable.
