HS Series Cast Iron Motorized Water Flow Control Plunger Valve

1 The open-close part is a piston-shaped cylinder. When the valve is closed, the open-close part is not affected by the medium blanking force, and the opening torque is very small (only 1 / 3-1 / 5 of the ordinary gate valve, butterfly valve and so on).

2 The open-close part is doing' linear motion driven by crank-slider mechanism, the relationship of valve flow coefficient and the valve open degree is approximately linear function

3 Fluid flows into valve via spindle-shaped fluid director, in any position Within the valve flow channel cross-section is low channel shape are circular ring. Compared with the traditional valve, the piston valve flow path is smooth, the fluid at any opening degree has no sharp turn, so the valve can be used in any operating conditions (such as high pressure difference without back pressure, high flow conditions), the valve works without cavitation and running noise.

4 At the valve outlet, the fluid direction and pressure changes, the fluid will appear cavitation, flashing phenomenon, small high-pressure steam bubble will be formed, if the bubbles attached to the valve or outlet pipe wall and rupture, will produce very high instantaneous impact energy, which will have strong destructive effect to valve and pipe. It is commonly known as cavitation. Piston valve using a spiral blades or squirrel cage fluid deflector, the bubble concentrated in the central part of the fluid and ruptures, greatly reducing the cavitation hazard.
