YI CHEN Q644F Pneumatic Carbon steel flanged cross ball valve

Q646F pneumatic cross ball valve working principle and flow diagram

"LL" cross type ball valve: a valve switch direction to water supply, each turn 90 °, the water supply way switch once, at the same time to switch of two kinds of medium flow, convenient and quick, achieve the effect of one valve is multi-purpose. When the water supply valve 1, 4, open, close valve 2, 3; Reverse when the water supply valve, 2, 3, open valve 1, 4, closed, with a four-way valves replacement now, easy to operate.

Q646F pneumatic four-way valves perform standard:

Design and manufacturing: 1 GB/T12237-1989; APl608

Inspection and testing: 2 GB/T13927-1992; APl (598).
3 flange connection: JB/T79] a 2-1994; ASME/ANSI B165.

Q646F pneumatic cross ball valve structure features and use:

1, small fluid resistance, sphere and body connection pipe cross section are equal, and arc sphere channel adopted, medium through the sphere is, fluid resistance is small.

2, sealed performance is good, the seat USES the elastic deformation and high strength of PTFE material, good sealing performance to ensure the stability of the valve.

3, long service life: see the neck of the valve core and light material austenite stainless steel, PTFE seat material selection, can achieve good corrosion resistance, extend the service life of the valve.FAQ
