Compact combination valve that features a thermal balancing and pressure reducing valve to reduce potential leaks

Reliance Valves Thermal Balancing and Pressure Reducing Valve is a compact single-piece unit that is designed to reduce leaks and save installation time and cost.

Used on circulating hot water systems, the combination valve reduces water pressure and balances the system by regulating the flow depending on the temperature. The valve is for use in hot water applications and incorporates a built in disinfection function to protect against Legionella.

The combination valve reduces design complexity and avoids installation errors. It also includes a 'Lift & Turn' tamperproof temperature adjuster cap (from 45 to 65°C) and a dry fit thermometer, which means the system does not need to be drained.
