ZFCM Internally threaded 2- and 3-way valves

Valves intended for on/off control of hot or cold water in heating or cooling systems. The valves can only be used together with Regin’s RVAFC actuators. The valves are available as both 2- and 3-way models.
  • Size DN15…DN32
  • Kvs value 3.2…10
  • Media temperature 2…94°C
  • Pressure rating PN16
  • Tight closing
Function
On demand, the valve is opened by a signal from a thermostat (supply voltage on). When the temperature reaches the desired level, the spring return mechanism will force the valve back to closed position. The sealing ball of the valve closes against the flow on the 2-way valves. In 3-way valves, the ball normally closes towards the coil side (see pictures below). On the side of the actuator there is a lever for manually opening the valve
