Valve manufacturer Crane Fluid Systems has announced launching a new range of compact differential pressure control valves (DPCVs) with features, which the company claims offer cost-saving benefits and reduced energy consumption, whilst still maintaining their high quality and reliability. They are available in sizes DN15 to DN50 and are PN16 rated and have an adjustable differential pressure range of 20 – 100kPa, it adds.

The manufacturer lists the following product features and benefits:

• Belonging to the FlowMaster range of commissioning valves, the DPCVs (F400 and R400) are quick and easy to install, have a long life expectancy and require little or no maintenance.
• The new design aids system analysis and simplifies circuits: Having threaded female ends, it reduces the need for additional adapters in most circuits and allows easy connections to alternative pipework solutions when adapters are required. There is an addition of two bosses for integral test point installation, which gives greater flexibility and reduces the need for separate test points within the circuit.
• With the two bosses, pressure readings can now be taken from before and after the control circuit. The pressure is linked to the upper and lower chambers and 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.
