The research and development of the piston valve VAG principle and introduction
And will only be used for the pipeline of butterfly valve and cut off, the piston valve is different gate valves can meet all kinds of special regulation requirements of the valve. The control function is to rely on a similar to the piston cylinder shape in the body cavity as axial movement to realize.

Product features

Design features: to adapt to different places in the factory of the fluid regulation requirements; The best cavitation characteristics; High circulation ability? Sealing system service life is long, metal and elastic material double seal, closed tight? The pressure balance, so need to drive the operation of small force according to the different requirements of operation condition, can replace parts stainless steel piston is reliable export guided sliding won't produce tilt and operation, can be installed in any position.

Working principle: water flow from the axial arc shape into the enclosure, no matter where the piston, the body cavity in any position are circular cross section water flow at the exit, the axis, thus to avoid for throttling contraction and possible cavitation erosion of the body and the destruction of the pipe, and at the same time adjusting performance, the standard size for linear for: 6 to 48.

Product features: fluid used in control valves; In the open conditions for circular cross section circulation; Linear regulation; Integration body; According to the different work conditions take different control components; Export parts of the crank by longitudinal mobile drive control; Standard configuration with a position indicator of the gear box; Flange standards comply with the EN1092, PN10/16 standards; The valve body length EN558 follow-1, basic sequence 15 (DIN3202, F4) standard.

applications

Water: VAG piston valve can be used as bleeder valve shall be equipped with vent device, ring, also used for explosion-proof pipe valves.

Storage: VAGLH type or E type piston the valve can be used as a liquid level or pressure regulator

Water: VAGLH type piston valve type or S can be used as flow regulator, E type or LH type can be used for irrigation pipe net put valve or valve.

Water treatment/sewage treatment: VAG E type piston valve can be used as BaoHuFa pump start-up, or equipped with special adjust export parts, also can use water treatment plant flow regulator. VAG E type piston valve may also serve as the sewage treatment plant volume regulator.

Water supply: according to the working conditions of different parts, used for export pressure/flow regulator, such as pipe pressure balance.
