Application

Suitable for HVAC applications.

Description

A differential pressure companion valve.


Features and benefits:

  • Specifically aimed at optimising system performance.
  • The DPCV is set to a maximum differential pressure which ensures flow cannot exceed a desired rate.
  • Helps reduce energy consumption, the risk of noise and simplifies the commissioning process.
  • Has an integral tapping point for the impulse tube to link with the Crane Fluid System DPCV.
  • Integral orifice and test points provide precise and accurate flow measurement.
  • Positive flow control at all handwheel settings.
  • Easy to operate with double regulating handwheel and numerical position indicator.
  • Can be used plugged, as supplied, for PN25 applications or with an impulse tube for PN16 applications.
  • Characterised regulating disk tends towards equal percentage performance.
  • Male threaded ends.
