Angle radiator thermostatic valve set Varioterm Premium PRNYGS05106C/FK 3/4" with nipples GS05106C/FP

The Varioterm Premium angle thermostatic radiator valve set PRNYGS05106C/FK with supplied nipples GS05106C/FP is a 3/4" angled valve assembly designed for thermostatic control of hot-water central heating radiators. It fits installations where the radiator connection is at an angle, allowing proportional regulation of water flow to maintain a target room temperature. The set includes the angled valve body and compatible nipples for a complete connection to radiator and pipework.

Advantages

This valve set provides stable, automatic temperature regulation through a thermostatic mechanism that adjusts flow according to room conditions. Its angled design simplifies installation where pipework approaches the radiator at a corner or horizontal offset, reducing the need for additional fittings. The included matching nipples ensure correct fitment and reduce installation time compared with buying components separately.

Suitable for

• Domestic and light commercial central heating radiators with angled inlet connections
• Systems that require thermostatic room-temperature control
• Retrofit or replacement projects where existing radiator connections use 3/4" fittings
• Installations where a compact angled valve reduces pipework clearance issues

When it may not be suitable

This angled thermostatic valve set is intended for use with standard hot-water central heating systems; it is not designed for use with steam heating or non-water heat transfer fluids. If the radiator system uses different thread sizes, special adapters or a different valve model will be required. High-flow industrial systems with nonstandard pressures or temperatures may need valves specified for those conditions.

Key specifications

• Valve type: angled (corner) thermostatic radiator valve
• Connection size: 3/4" nominal radiator connection
• Includes matching nipples for direct connection to radiator and pipe
• Control: thermostatic regulation of hot-water flow to radiator
• Intended medium: hot-water central heating

How to use

Install the valve set in place of a manual radiator valve on the radiator inlet using the supplied nipples to secure the connection. Ensure the heating system is depressurised and drained at the installation location before removing existing components. Fit the angled valve body to the radiator inlet and connect the pipework using the nipples, tighten fittings to recommended torque, then refill and vent the radiator to remove air. After restoring system pressure, set the thermostatic head to the desired room temperature and allow the valve to modulate flow automatically.

What to consider before purchase

• Confirm radiator inlet thread size and compatibility with a 3/4" angled valve
• Verify the heating system uses hot water and operates within standard domestic pressure and temperature ranges
• Check workplace or installer access for angled valve orientation and clearance
• Ensure the included nipples match the pipe material and fitting type used in your installation

Usage recommendations

For reliable operation, have the valve installed or checked by a qualified heating engineer, bleed radiators after installation to remove trapped air, and operate the thermostatic head within its intended temperature range. Periodic inspections during annual maintenance will help maintain accurate temperature control and leak-free connections.
