pneumatic cross ball valve structure characteristics and USES

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

2, sealed performance is woman: 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: valve of the valve core and light neck austenite stainless steel material, the seat material chooses PTFE, rubber fluorine ball valve can achieve good corrosion resistance, prolong the service life of the valve.

 pneumatic cross ball valve standards:

I design and manufacture of: GB/T12237-1989. APl608.

2. The inspection and testing: GB/T13927-1992; APl (598).

3 flange connection: JB/T79] a 2-1994; ASME/ANSI B165.

flow direction of medium four-way valve principle

"LL ' 'type spool valves, electric spool valves will only operate wrench or actuator sphere rotating 90', but for the two kinds of medium flow switch, is convenient and rapid, achieve the effect of one valve is multi-purpose.
