Description
Stable flow rate without manual balancing
The Belimo EP040R+MP electronic pressure-independent control valve is specially designed for precise hydronic control in heating and cooling systems. The integrated flow measurement compensates for pressure changes, so the set volumetric flow rate is maintained. The DN40 size clearly indicates which pipe diameter this version is intended for.
The EPIV combines a control valve, actuator and electronic flow control. As a result, the valve responds to the actual flow rate instead of only the valve position, making control behavior predictable under varying operating conditions.
