Product information

Description

The Sourcing thermostatic valve V81112B50 for radiators with 1/2" x 3/4" connections is a mechanical control valve designed to regulate coolant flow to panel convectors and radiators. It enables automatic temperature maintenance by responding to a thermostatic head (sold separately) and is suitable for replacement of standard angled radiator valves or for upgrading a heating circuit to provide proportional flow control. The compact brass body and threaded connections make it compatible with typical residential and light commercial heating installations.

Advantages

This thermostatic valve provides stable automatic temperature regulation when combined with a compatible thermostatic actuator. Its angled 1/2" x 3/4" connection format fits common radiator inlet fittings, simplifying replacement and retrofit jobs. The valve construction is aimed at reliable operation in closed hot-water heating systems and is intended to improve occupant comfort and energy use by allowing more precise room-level control.

Suitable for

  • Domestic radiators with 1/2" or 3/4" inlet fittings (angled connection)
  • Panel convectors and compact radiator installations
  • Replacing worn or non-thermostatic angled radiator valves
  • Upgrading heating circuits to use thermostatic heads for room temperature control

When it may not be suitable

This valve is designed for use in conventional hot-water heating systems and requires a separate thermostatic head or actuator to provide automatic temperature setting; it is not an electronic or standalone thermostat. It may not be appropriate for systems that use non-standard connection sizes, hydraulic balancing valves integrated into the radiator, or where special corrosion-resistant materials are specified.

Key specifications

  • Connection type: angled valve with inlet/outlet threaded connections sized 1/2" x 3/4"
  • Application: radiator and panel convector flow regulation
  • Material: brass valve body (plated finish typical for heating valves)
  • Control method: thermostatic valve body requiring a compatible thermostatic head or actuator
  • Suitable medium: water/glycol mixtures commonly used in closed heating systems
  • Mounting orientation: angled installation on radiator inlet

How to use

Shut off the heating circuit and drain the section of the system before removing an existing valve. Fit the Sourcing thermostatic valve into the radiator inlet using the appropriate thread seal and tighten to the manufacturer-recommended torque. Install a compatible thermostatic head on the valve spindle according to the head's instructions. After refilling and venting the system, check for leaks and operate the thermostatic head through its range to confirm smooth valve action and proper temperature response.

What to consider before purchase

  • Verify radiator inlet thread sizes and angles to ensure 1/2" x 3/4" compatibility
  • Confirm that a compatible thermostatic head or actuator is available and suitable for your control needs (sold separately)
  • Check that materials and finish meet any local corrosion or building code requirements for heating systems

Usage recommendations

For best results, combine the valve with a thermostatic head from the same specification range and perform proper hydraulic balancing of the heating circuit after installation. Regularly inspect for leaks and service the valve and head according to the heating system maintenance schedule.
