High-Performance Electric Plunger Valve for Precision Flow and Pressure Control in Water Supply Systems
Product Overview

Our Multi-jet Plunger Flow Control Valve is engineered for high-pressure water systems requiring linear regulation and superior cavitation resistance. Unlike standard butterfly or gate valves, the plunger design ensures a concentric flow path, minimizing vibration and noise even under extreme differential pressures.

Technical Specifications
Feature Specification
Valve Type Plunger / Needle / Multi-jet
Size Range DN200 - DN2000 (Customizable)
Pressure Rating PN10, PN16, PN25, PN40
Actuation Electric Actuator (with manual override handwheel)
Body Material Ductile Iron (GGG40/50) or Carbon Steel
Coating Fusion Bonded Epoxy (FBE) - Drinking Water Approved
Connection Flanged (ISO, DIN, ANSI, BS)
Key Advantages
  • Precision Flow Regulation: The plunger moves axially, ensuring the flow area changes linearly with the valve stroke. This allows for pinpoint accuracy in flow and pressure management, making it ideal for reservoir outlets and city water networks.
  • Advanced Anti-Cavitation Design: Equipped with a Multi-jet orifice cage, the valve breaks the water flow into multiple small jets. This shifts the cavitation zone to the center of the pipe, protecting the valve body and internal components from erosion and extending service life.
  • Low Operating Torque: The internal pressure-balanced design ensures smooth operation even under high pressure, reducing load on the electric actuator and lowering energy consumption.
  • Corrosion & Wear Resistance: Finished with high-quality blue epoxy coating, our valves are resistant to chemicals and abrasion, ensuring reliable performance in harsh environments or underground installations.
Common Applications
  • Pressure Management: Reducing high-pressure trunk lines to manageable distribution levels
  • Flow Regulation: Maintaining constant flow rates in irrigation and water treatment plants
  • Reservoir Management: Discharge valves for dams and water storage facilities
  • Pump Protection: Preventing surge and backflow in large pumping stations
Frequently Asked Questions
How does a plunger valve prevent cavitation in high-pressure systems?
A: Unlike standard valves that create a single high-velocity flow stream, a Multi-jet Plunger Valve uses a specialized internal cage. This cage divides the water into numerous small "jets" that collide in the center of the valve. This design ensures that the energy dissipation and potential cavitation bubbles occur in the water stream itself, away from the valve body and pipe walls, preventing erosion and vibration.
What is the difference between a Plunger Valve and a Butterfly Valve for flow control?
A: While Butterfly valves are excellent for "On/Off" service, they struggle with precise regulation and often suffer from cavitation at partial openings.

Plunger Valve: Offers linear flow characteristics, meaning the flow rate changes proportionally to the valve's position. It is designed for continuous regulation under high differential pressure.

Butterfly Valve: Best for isolation. Using it for long-term throttling can lead to seal damage and hydraulic instability.
Why is the "Linear Flow Characteristic" important for water conservancy?
A: A linear characteristic (Q ∝ Step) allows for much simpler and more stable automated control. In large-scale water supply projects, this prevents "water hammer" effects and pressure surges, protecting the structural integrity of the entire pipeline network.
Can this electric plunger valve be operated manually during a power failure?
A: Yes. Our valve is equipped with a high-torque Electric Actuator that includes an integrated manual handwheel. The internal pressure-balanced design ensures that even at DN2000 sizes, the valve can be operated manually with reasonable force during maintenance or emergencies.
