Product description
The F403 is the return side valve of a manual thermostatic pair. It has no handwheel, because the return side of a radiator does not need to be adjusted, and it is locked to the return connection of the radiator. Nickel plated brass, with the same standard or self-sealing tail as the flow valve so both ends of the installation look the same.

- Matches the F402 flow valve
- Nickel plated brass body
- Self-sealing tail option
- Every valve is 100 percent air tightness tested before packing
