Control valve Clorius M2FR large

Mainly M2FR valves are intended for operation in cooling and heating systems. These valves are used in conjunction with differential temperature or pressure controllers. Since the reversing valves are held closed by an integral spring, the maximum pressure, ΔpL, that the valve can close depends on the spring that the actuator must overcome during opening. Below you can find the maximum allowable pL values as well as the maximum allowable inlet pressures for opening the valve, p1max, at various actuator forces.
