Pneumatic O-Type Cut-off Ball Valve

Key Features

• The valve body is made of precision casting or forging. The structure is compact and the appearance is beautiful. Fixed O type ball valve, spool and stem rotation, rotating spool valve, valve seat always close contact, with a strong shear capacity;
• Seat by cylindrlcal spring or butterfly spring preload, with automatic compensation, self sealing and valve cavity automatic pressure relief function, suitable for high temperature, high pressure occasions;
• Ball valve fixed to ensure the smooth operation of the ball valve, reducing operating torque;
• Double break design ensures that the b<1II valve is fully opened and fully closed. A variety of sealing structures are available to ensure service life and reliability. Sealing structure can be selected before the valve seat seal (recommended), valve seat seal, va|归 beforethe valve sealing (specific working conditions). Sealed with hard and soft sealing, optional, sealed surface hardening treatment, suitable for a variety of working conditions; The design of automatic relief valve pressure cavity
• in valve body cavity for medium temperature rise caused by abnormal pressure, without going through the safety valve, and the valve seat can function alone automatic pressure relief, improve the safety valve in the delivery of liquid medium;
• Grease emergency ambulance, in some special occasions, as the foreignmedia or fire caused by failure of the valve seat sealing, grease valve provides a quick connection with grease gun, quickly injected into the valve seat seal grease seal, relieve leakage;
• Can choose fire protection structure, anti-static structure, anti stem blowlng structure design;
• Long stem design, suitable for low temperature occasions.
