INTA 22mm LOW PRESSURE SOLAR RATED THERMOSTATIC MIXING VALVE

INTA 22 mm Low Pressure Solar Rated Thermostatic Mixing Valve

The INTA 22 mm Low Pressure Solar Rated Thermostatic Mixing Valve is engineered for solar hot water systems and high‑temperature applications where conventional blending valves struggle. Designed to deliver safe, usable domestic hot water temperatures, this solar rated valve handles high inlet temperatures with minimal pressure loss making it ideal for solar thermal systems, unvented cylinders, and low pressure domestic hot water circuits.

Built in durable DZR brass and optimised for high flow and low pressure drop, this mixing valve ensures stable temperature control and reliable performance in demanding environments. It’s the professional’s choice for solar and renewable system blends where precision and safety are critical. 

Why You Should Buy This Valve

✔ Solar Rated Performance – Specifically designed for solar thermal and high temp hot water systems where standard mixing valves cannot cope.
✔ High Flow, Low Pressure Loss – Excellent performance with minimal impact on system hydraulics — ideal for low pressure installations.
✔ Robust Build Quality – Manufactured in dezincification‑resistant brass (DZR) for long service life and corrosion resistance.
✔ Wide Operating Range – Suitable for high inlet temperatures (up to 110 °C) without compromising safety.
✔ Professional Reliability – Precise thermostatic control with good temperature stability (±2 °C) for consistent delivery.
✔ Simplifies Compliance – Helps ensure domestic hot water is delivered at safe, controlled temperatures — especially important in solar and renewable system setups.
