Radiator Valves

Radiator valves regulate the flow of hot water or steam into a radiator, allowing room-by-room temperature control in hydronic heating systems. Thermostatic radiator valves add automatic temperature regulation, adjusting flow based on the room's temperature.

Furnace Part Source carries a range of radiator valve components, including valve bodies, thermostatic operators, remote sensors, and related tool sets for servicing hydronic radiator systems.

Common Radiator Valve Parts We Carry

Common replacement parts in this category include:

  • Straight, angle, and side-mount valve bodies for different radiator piping configurations.
  • Thermostatic operators that automatically adjust flow based on room temperature.
  • Remote sensor and dial kits for radiators in enclosed or hard-to-reach locations.
  • Service tool sets for installing and adjusting radiator valve components.

How to Find the Right Radiator Valve

Before ordering, check the existing valve body or operator for the part number and connection size. Radiator valves are available in straight, angle, and side-mount configurations, so confirm the mounting orientation of your existing valve.

For best fit, compare:

  • Original valve part number
  • Connection size, such as 1/2", 3/4", or 1 1/4"
  • Valve body configuration, such as straight, angle, or side-mount
  • Operator type, including standard or remote sensor

Radiator Valve FAQs

Does turning a radiator valve higher make the room heat up faster?

No. Turning the valve higher sets a higher target temperature, but it does not speed up how quickly the room reaches that temperature.

Can I replace just the thermostatic operator without the valve body?

In many cases, yes, since the operator and valve body are often designed to be serviced separately. Confirm that the replacement operator is compatible with your existing valve body.

What is a remote sensor radiator valve used for?

A remote sensor kit allows the temperature sensor to be mounted away from the radiator, which is useful when the radiator is enclosed, covered, or located somewhere that would give an inaccurate temperature reading.

Do I need a special tool to service a radiator valve?

Some radiator valves require a specific tool set for installation and adjustment. Check the product listing for compatible tool sets before beginning service.
