PICV Valves & Actuators
Pressure independent control valves are an automatic temperature control valve and an automatic flow regulating valve packaged in one valve body. A ball valve with a characterized insert performs as a regular actuated temperature control valve, and a pressure control cartridge provides automatic flow regulation to maintain a constant flow of hot or chilled water regardless of system pressure changes. They are used in many closed loop HVAC applications. Systems with pressure independent control valves do not need to be balanced and rebalanced during commissioning. They regulate and maintain a constant flow to the coil as water pressure in the system varies with the changing loads. This delivers better comfort, increases energy efficiency, reduces actuator operation and reduces expensive call backs. Pressure independent valves allow the system to perform better. With the right flow to each coil, boilers and chillers are most efficient.
- Simple planning and implementation of energy-efficient HVAC systems
- Flexible planning thanks to continuous volumetric flow ranges and large differential pressure ranges
- Simplified dimensioning, presetting, hydronic balancing, and commissioning
- Easier system extension with independent pressure control
