Ball valve 2 piece din flanges full bore VN
Features
Resilient seat design
The seat sealing part is designed with elastic structure, it effectively reduces the operating torque of the valve stem, making it easy to open and close, and makes low and high pressure sealing more reliable
Sense lock
Bolt that prevents unwanted movement of the valve
Disc spring
Two properly pressed springs that compensate the possible deformation of the joint before its compression to guarantee the tightness of the gasket
Multiple stem sealing
The lower gasket, the intermediate O-ring and the multi-seal packing effectively ensure the total tightness of the stem
Anti-blowout stem
The lower part of the stem is provided with a raised shaft. Even if the nut is removed, the stem will not come out of the body, ensuring the safety of the body
FIRESAFE structure
When a fire breaks out in the surrounding area, the valve seat burns and the ball recedes under the valve. The ball is pushed back by the force of the fluid and contacts the flame retardant lip of the body to help seal and reduce media leakage
