What it is

A 2-way open/close ball valve made by Belimo, DN40 with a Rp1½" internal thread, used for shut-off and on/off control in heating, chilled and hot water systems. The valve body is supplied without an actuator — it is driven by a separately-ordered Belimo rotary actuator.

Signs this part needs replacing

  • Valve won't fully open or close, or leaks past the seat when closed
  • Water leaking from the valve body or stem seal
  • Actuator moves but no change in flow occurs
  • Visible corrosion, scoring or pitting on the ball or housing

Before you order

  • Confirm this is the valve body only — a compatible Belimo rotary actuator is needed and ordered separately
  • Match the DN40 / Rp1½" thread size to your existing pipework
  • Isolate and drain the system before removing the old valve
