1.Regulating water level and pouring sand
2.Water supply system control hydraulic sections.
3.Thermal power plant jet condenser before precisely control water pressure.
4.A variety of water supply network relief pressure, decompress and regulate flow.
Piston valve are similar to one of the cylinder piston cavity in the valve for axial movement to change the medium flow area between piston and sealing surface, so as to achieve the purpose of regulating flow. The main features are following:
1.Close pieces are the shape of piston.
2.Turn off pieces for axial movement. Actuator is slide-crank mechanism.
3.The flow pours from the axial entrance in to valve body.
4.Any location of valve chamber cross-section is circle.
5.Outlet seat adopts spiral fanleaf export or squirrel-cage coil export.
6.Sealing surface use double sealing type of metal and resilient sealing.
1.Valve can be flow in the whole frame work of regulation, applicable to water supply engineering and air-cooled unit Heller System regulating flow pressure.
2.The valve can be used in variety fields such as adjusting media and throttling sealing.
3.Critical flow is high.
4.Low cavitation, because of the use of streamline body import, export spiral fanleaf circle, so the cavitation damage can be reduced to the minimum.
5.The sealing surface is bi-directional sealing of metal and resilient rubber.
Main technical parameters
