Motorised spring return 1''/ 3/4'' , 3 port valve

PMV31/PMV34 Motorised spring return 1''/ 3/4'' , 3 port valve
PMV motorised valve (ON/OFF type) designed for domestic heating applications.

A motorised valve is used to control the flow of water in a central heating system. The motorised valve can be used for control of both heating and hot water, and it works by controlling the flow of water from the heating boiler to other parts of the system. Valve actuator has a built-in switch, which can be used for switching On/Off (or Start/Stop) e.g. a fan or pump when the valve is fully open.

PMV valves are using in:
• in heating installation
• in heat and cooling water systems
• in solar collector systems
• the choice of priority for hot water/heating system (as a divider/separator)
• in solid fuel furnace boiler systems (as a divider/separator)
  • High durability and reliability
  • Removable actuator assembly
  • Manual lever and position indicator
  • Spring return
  • Industry standard wiring
  • Rigid construction
