Q645F overview:
Q645F pneumatic three ball valve is mainly used in corrosive or non corrosive liquid, gas, powder, and mixed medium to achieve switching shunt; opening and closing process, unobstructed flow path reduces the pressure loss, easy operation, convenient maintenance; five types to meet different process requirements, can be hand, pneumatic and electric. Control. Three pneumatic valve can be divided into L type pneumatic three ball valve and T type pneumatic three ball valve, L - (Q44F) three valve for switching the flow of media channels, can make the two mutually perpendicular connection; T (Q45F) three ball valves for medium diffluence and confluence and flow switch. The three channel of the T shape can make the three channels communicate with each other or make the connection between the two channels. Three way ball valve generally uses two seat structure, can also be based on user requirements for the use of four seat structure.
Q645F pneumatic three way ball valve features:
1, compact structure, open and close rapidly, smooth flow, small fluid resistance.
2, good sealing performance: the use of four seat material PTFE elastic deformation to achieve no leakage seal.
3, a valve multi-purpose: any port can be used as the entrance without leakage, the three can be made into L type mouth, can also be made into T type mouth.
4, easy maintenance: after the system pressure relief, no need to remove the entire body can be checked and maintained.
5, widely used in water supply, petrochemical, metallurgy, mining, textile, energy, paper, food, steel and other piping systems in the direction of the flow of media and streaming media or mixed fluid.
