V type pneumatic ball valve is the new development of the hard seal, PTFE seal ball valve. It uses a spring loaded movable seat structure, valve seat and ball will not produce V type pneumatic ball valve (13) raw waste or from the card and other issues, reliable sealing, long service life. V type ball valve core is designed with a special type of V type gap, flow capacity, pressure loss is small, and has the exact characteristics of the closure and control functions, flow characteristics, such as the approximate percentage. Opening and closing pieces by V segment structure, completely solve the problem of cavity deposition of medium valve.
Pneumatic V type ball valve is a right angle rotary valve, which is composed of GT pneumatic piston actuator (single or double effect) and V type ball valve is composed of two parts. Its sealing formalism has two kinds of soft seal and metal hard seal. The pneumatic V type ball valve is a right angle rotary structure, when the spool rotates relative to the valve seat has the strong effect of shearing, especially suitable for medium and small particles with fiber control. The company is widely used in petroleum, chemical, electric power, papermaking, metallurgy and other industries.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, caliber. Specific please contact or online advisory contact.
