Description
Crane D995 DN40–DN50 Pressure Independent Control Valve (PICV)
High-Capacity Pressure Independent Control Valve for Commercial HVAC Systems
The Crane D995 DN40–DN50 Pressure Independent Control Valve (PICV) is engineered for medium and large HVAC applications requiring accurate flow control, hydraulic balancing, and long-term energy efficiency. Designed as part of the Crane Peak Pro range, the D995 integrates differential pressure regulation, flow balancing, and modulating control into a single compact valve, reducing installation complexity while ensuring stable system performance.
Suitable for DN40 and DN50 pipework, the valve is optimized for Air Handling Units (AHUs), large Fan Coil Units (FCUs), heat exchangers, chilled water systems, and district energy networks. It maintains the preset design flow automatically, regardless of pressure fluctuations within the system, improving occupant comfort while minimizing pump energy consumption.
