Needle valve variants and configurations

We offer a wide range of high quality needle valves (plunger valves) in different configurations and with optional extras for actuation and cavitation prevention.

Dedicated software for precise size calculation

Each valve is specified according to relevant selection criteria for its specific application. Upon order or request it is therefore mandatory to provide information about hydraulic data (flow rate and pressure), installation design and requested actuation. This ensures that the valve has an optimal performance for the given installation. By using our dedicated software for sizing calculations, we provide a fluid and cavitation report under the hydraulic conditions. The report will guarantee a cavitation free valve.

Needle valve configurations

We offer a selection of optional extras for actuation and cavitation prevention. Each valve is fitted to the actual operating data and works without cavitation even at major pressure differences.

Needle valves with actuation

Upon request we can provide needle valve solutions with custom designed actuation configurations:

  • Worm gear box and handwheel
  • Electric actuator
  • Hydraulic
    • Hydraulic brake and lift unit
    • Double acting hydraulic piston
    • Simple acting hydraulic piston
  • Double or single acting pneumatic actuator

Needle valves with cavitation trim

Accessories are available for prevention of cavitation:

  • Intrusive
    • Dissipating cylinder
  • Non intrusive
    • Dissipating plate
    • Venting device
