New from Crane

Crane Fluid Systems, a leading brand of Crane Building Services & Utilities has launched a range of differential pressure control valves (DPCVs).

Part of the ProBalance range of commissioning valves, the DPCV is compact and modern in design and is available for both flow (DPAF951) and return (DPAR951) configurations in sizes DN15 to DN50.  The DPCV operates across a temperature range of -10 to 100?C and is PN16 rated.

Pressure is tapped from before and after the load and linked to the upper and lower chambers. The diaphragm, which separates the chambers and pressures, controls the rubber-seated piston to stabilise the pressure differential. The piston closes the valve on rising differential pressure and opens it on falling differential pressure. The valve will continue to move in this way until equilibrium of pressure is achieved.

The DPCV can be set on installation to a maximum differential pressure limit of 20 to 100 kPa. Under dynamic balancing conditions the valve can then be adjusted easily on commissioning as conditions dictate.
