Application Scenarios of Trunnion Ball Valve (Forced Sealing Ball Valve)

The trunnion ball valve (forced sealing ball valve) adopts high-precision ball shaft processing technology and high wear-resistant bottom friction coefficient bearings to reduce the torque of the valve and improve the service life of the valve.

Trunnion ball valve (forced-sealing ball valve). The surface of the ball core is clad with a layer of hard and polished sealing surface, which can ensure sealing performance under very harsh conditions.

The trunnion ball valve (forced sealing ball valve) has a high CV value in both full and standard diameters, which enhances the system efficiency of the valve and minimizes the problem of erosion.

Trunnion ball valve (forced-sealing ball valve). The second graphite seal design ensures fire safety, and the ball, valve stem, and valve body are connected through anti-static devices to prevent static electricity accumulation.

Testimonial
Trunnion ball valve(forced sealing ball valve) Because of its unique structure, it adopts the new technology design of valve seat rotation separation opening and mechanical pressing, the most outstanding advantage is that the sealing surface does not produce friction, Long service life, low operating torque, even if the medium contains solid particles, mud, short fibers and other impurities, under the harsh conditions of high-speed concentrated flushing of the sealing body, the fluid medium can maintain good sealing, ensuring safe and reliable operation during the maintenance of engineering equipment.
Trunnion ball valve (forced sealing ball valve) has replaced traditional cut-off valves such as gate valves, stop valves, ball valves, and plug valves, and is widely used in petroleum, natural gas, chemical, paper, power station, iron and steel, ecological environment protection, and sewage treatment industries.
Long Life and Mechanical Mold Sealing of Trunnion Ball Valve (Forced Sealing Ball Valve)
Trunnion ball valve (forced sealing ball valve): When the ball core deviates from the seat, the fluid washes away the debris in the sealing zone along the sealing surface 360 degrees, and replaces those defective ball valves, gate valves, stop valves, and plug valves. The unique performance of inter-door opening will reduce the number of parking times of the equipment and reduce the cost of the owner. The cam surface at the bottom of the reading rod provides mechanical pre-tightening force to ensure sufficient sealing pressure.
The main material of trunnion ball valve (forced sealing ball valve) is WCB, A105, LF2, LCB stainless steel, etc.
Trunnion ball valve (forced sealing ball valve): The rigid rod guide and guide pin control the up and down movement and rotation of the valve stem.
