## Summary description

Thermostatic valve Sourcing V81112Q50 is a 1/2" x 3/4" valve with 50 mm connection length for temperature regulation in heating systems. Designed to control and maintain set water temperature, it suits radiators, underfloor heating manifolds and domestic heating circuits. The valve provides precise flow adjustment and stable thermal control where a 50 mm fitting is required.

## Long description

The Sourcing thermostatic valve V81112Q50 1/2" x 3/4" 50 mm is a thermostatic control component for hydronic heating systems. It is intended to regulate and maintain set water temperature by modulating flow to radiators, underfloor heating manifolds or other heating circuits. The valve body and 50 mm connection length make it suitable where a compact thermostatic fitting is required and where precise temperature control is needed for consistent room comfort.
Advantages
This thermostatic valve offers accurate temperature regulation through a built-in sensing and control mechanism that adjusts flow according to setpoint. The combination of 1/2" and 3/4" connection sizes with a 50 mm connection length supports compatibility with common radiator and manifold installations. The product is designed for stable operation in closed heating circuits and enables straightforward integration into existing systems without extensive piping modifications.
Suitable for
Domestic radiator installations that require a 50 mm connection length
Underfloor heating manifolds needing thermostatic control
Small to medium-sized heating circuits in residential or light commercial buildings
When it may not be suitable
The valve may not be suitable for systems that require different connection lengths or non-standard thread types; it specifically fits installations using 1/2" and 3/4" connections with a 50 mm length. It is not intended for use with fluids other than heating water or in open systems where thermostatic control is incompatible with the system design.
Key specifications
Connection sizes: 1/2" and 3/4"
Connection length: 50 mm
Function: thermostatic temperature regulation for heating circuits
Application: radiators, underfloor heating manifolds, domestic heating circuits
How to use
Install the thermostatic valve in the heating circuit at the radiator or manifold connection following standard plumbing practice and local codes. Ensure the matching connection sizes and 50 mm fitting length align with the installation point. After mechanical installation, set the desired temperature according to the valve control instructions and bleed the radiator or circuit to remove trapped air. Verify stable temperature control by observing system response during a normal heating cycle and adjust settings as necessary.
What to consider before purchase
Confirm the required connection sizes and that a 50 mm connection length is compatible with your radiator or manifold
Verify that the valve is intended for closed heating water systems and suitable for the fluid and temperature range in your installation
Check compatibility with existing fittings and whether adapters or additional piping modifications are needed
Usage recommendations
For reliable performance, install the valve in a position that allows access for adjustment and periodic maintenance. Use with clean heating water and follow system flushing guidelines before installation to reduce the risk of debris affecting thermostatic operation.
