Blending Valve & Thermostat Head

The Blending Valve & Thermostat Head is the complete control pack every underfloor heating installer needs. Designed specifically for manifold systems, this thermostatic mixing valve gives you precise temperature control from 20°C to 65°C – ideal for safe screed drying and every type of floor construction. Engineered for performance and reliability, it features a remote probe actuator, a locking pin to set your maximum blend temperature, and an extra probe pocket for an over-temperature safety device. A built-in throttle lets you increase the Kv value for bigger systems, while the built-in non-return valve prevents back-filling during filling and makes maintenance quick and clean. Key Features & Benefits • Precision mixing valve with built-in thermostatic actuator (20–65°C range) • Complies fully with BS 1264-4:2009 for safe initial warm-up temperatures • Precision-engineered materials for long life and excellent performance • Integrated flow-rate control valve for perfect temperature and flow regulation • Standard 210 mm manifold spacing with 1″ BSP connections – fits almost every manifold • Built-in thermometer (0–120°C), auto air vent, and bracket to support the weight of the circulation pump • Extra throttle for larger systems and non-return valve for easy maintenance Compact design with 210 mm manifold centres, overall height 354 mm and width 202 mm (full diagram in the datasheet). Includes everything you need for fast installation.
