WRAS Approved Group Thermostatic Mixing Valves

Reliance Water Control’s Heatguard Planar range is a group thermostatic mixing valve for high flow rate group mixing applications.

Heatguard Planar thermostatic mixing valves are ideal for multiple outlet shower or basin installations where stable outlet temperatures at varying flow rates are important.

Heatguard Planar Thermostatic Mixing Valve - WRAS Approved

The Heatguard Planar thermostatic mixing valve has two quick reaction wax thermostats to provide temperature control and has an optional user-adjustable or tamperproof function to provide the user with flexible control and is WRAS approved.

The Heatguard Planar mixing valve comes with 4-in-1 fittings comprising of a full flow, chrome-plated ball type isolating valve and high flow barrel type strainer which protects the check cartridge/non-return valve from system contamination. 

Additionally a ¼” BSP test point is included to allow for the monitoring of system conditions such as temperature, pressure and cross-flow.
