Features and Benefits Control the water flow running inter-collide inside the valve channel, inter-reaction the power, lower down the noisy, avoid cavitations corrosion. Counter balance structure, reduce the operation torque under high pressure and high flow rate. Linear regulation design cage disc, 100% linearly modulate the flow rate, for different application requirement. Metal to metal sealing, smooth surface finish 0.8m, 0 leakage sealing. Inner material stainless steel, corrosion resistant, long life cycle. Bronze bushing, self-lubricating, reduce friction, lower the torque. Flow rate regulating, pressure modulating, fluid level control, and water draining function. Variety operation solution, gear box, pneumatic actuator and motor operation are all available, with customized control device depending on operating conditions. Low actuating torque due to pressure balanced valve piston. Rotationally symmetrical flow guidance.
