Description
951/20 PICV PRESSURE INDEPENDENT MOTORIZED CONTROL BALANCING VALVE
951 Flowmaster™ Pressure independent control balancing valves – PICV offer the combined benefits of optimal modulating flow control valve, differential dynamic pressure balancing control, and manual balancing valve – all in one – for air-handling units, fresh air units, fan coils and all other terminal equipment. Cost saving: A single 3-in-1 PICV replaces three other valves saving on investment and installation cost. Safe: Balancing made safe during design, installation and remodeling for designers and installers. Comfortable: Increased comfort for users due to ensured balancing and precise modulating temperature control. Energy saving: Inbuilt fast response balancing regulator reduces energy consumption and pump size

100% valve authority is always achieved that’s to the differential pressure balancing module
Precise balancing and high flow rates also in low pressure conditions
Automatic balancing of the flow across the valve regardless of pressure fluctuations in system
Easy cleaning of the valve core
Normally closed actuators compatible with all control signals
Manual flushing possible without the actuator
Operational pressure up to 400 kPa
Continuously variable analog adjustment provides accurate preset function.
Control accuracy of up to 3% and won a national third party verification.
