Regulator Section The control valve is throttled to match the flow command of the control signal.
Pressure Independent Control Valves | Belimo
The differential pressure regulator holds the pressure drop across the ball of the valve. As system pressures change, the differential pressure regulator moves in response to keep the flow stable. When differential pressure increases the regulator opening is reduced.
Piccv belimo differential pressure decreases the regulator opening is increased. This allows for the constant pressure differential across the ball of the valve. P1- Upstream pressure entering valve. P3 P3 P3 Piccv belimo is downstream of the ball as well as piccv belimo diaphgram.
Low pressure pulls regulator down against the spring force.
The PICCV is a two-way valve that will supply a specific flow for each degree of ball opening regardless of pressure variations piccv belimo a system. PICCVs are available in flow values from 0.
To achieve higher flows, it is recommended to pipe piccv belimo two valves in parallel. This recommended configuration provides the control of flows up to GPM by using two valves.
The top diagram details valves piped in a parallel arrangement. The bottom diagram features a typical single piping arrangement. If piccv belimo than three valves are piped in parallel, please call Belimo to discuss piccv belimo options.
Does order require tagging? Valves may be tagged per customer specification. Product Features Constant flow regardless of pressure variations in the system at set degrees of ball opening.
Simplified valve sizing and selection, no Cv calculations required. Valve is supplied at maximum flow in the full open position only.

Field adjustment is necessary piccv belimo acheive lower flow. Some other common applications include unit ventilators and VAV reheat coils. Piccv belimo valve is suitable for use in a hydronic system with constant or variable flow.
This valve is designed with MFT functionality which facilitates the use of various control input.
Regulator piccv belimo Spring Body pressure rating Media temp. Piccv belimo The Pressure Independent Characterized Control Valve is typically used in air handling units on heating and cooling coils, and fan coil unit heating or cooling coils.
Some other common applications include unit ventilators and VAV re-heat coils.
The PICCV regulator modulates in response to differential pressures in the system to maintain a constant piccv belimo pressure across the ball of the valve. The PICCV will maintain a constant flow at part load and during morning start-up when all piccv belimo become critical.
With the PICCV, each terminal gets the required flow, no overflow or underflow at this critical time.
