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 ≤0.8µm, 0 leakage sealing.
• Inner material stainless steel, corrosion resistant, long life cycle.
• Bronze bushing, self-lubricating, reduce friction, lower the torque.
Product Application:
This production shall be provided to isolate a system or equipment for the purpose of:
• Water draw: PLG1 Plunger Valves can be used for adjust the pressure rate and flow regulating in gravity draw pipeline.
• Water storage: PLG1 Plunger Valves can be used for the fluid lever control.
• Water supply: PLG1 Plunger Valves can be used as a control valve with different assembly parts, for pressure/flow modulating.
• Water draining, PLG1 Plunger Valves can be used as a by-pass blow-down valve for dams and hydropower station, etc.
• Water transportation: PLG1 Plunger Valves can be used for flow rate adjust and pressure regulating, meanwhile, the valve have the performance to avoid the pipeline burst.
• Water treatment: PLG1 Plunger Valves can be used as a protection valve for pump start, also available for the air capacity modulation in sewage treatment plant.
• Flow rate regulating, pressure modulating, fluid level control, and water draining function.
• Variety operation solution, gear box, pneumatic actuator and motor operation available, with customized control device depending on operating conditions.
• Low actuating torque due to pressure balanced valve piston.
• Rotationally symmetrical flow guidance.
• Annular flow cross section in each position.
• Axial movement of the plunger by means of crank gear mechanism.
• With self-locking worm gear unit including position indicator.
• Elastic profile sealing ring located in the no-flow zone for high durability.
• Wear-resistant, corrosion-resistant and infiltration-proof piston guides in the body by micro-finished stainless steel.
