Crane Fluid Systems PN16 rated control valves offer a compact and lightweight solution for a variety of variable flow and constant flow applications. Designed to work as a Normally Closed control valve, manufactured in Europe to the highest quality and precision you expect from Crane. Our D103B (3 port control valve) or D104B (4 port control valve) allow for easy mounting onto terminal units for heat output control as well as end of line pipework solutions for minimum pump turndown. This improves water treatment circulation, leading to better heat or chilled response times, whilst still offering energy savings.

Crane D102B, D103B and D104B valves can be combined with the ACT992TH to give on/off control, or with the ACT991M actuators for modulating control, providing the complete package for fast and reliable BMS connection and control of variable flow systems.
