The Heatguard® 135 is a compact Thermostatic Mixing Valve that mixes hot water with cold to deliver tempered water at a constant temperature.

The Heatguard® 135 is specifically intended for use in conjunction with individual faucets and electronic sensor faucets.

The Heatguard® 135 is a compact, high specification product incorporating the latest in Thermostatic Technology. It features a robust design based on expertise gained from years of experience in the design and manufacture of safety valves. Every valve is tested for performance on an automated testing station during the assembly process. The valve is third-party listed for individual point-of-use applications.

The Heatguard® 135 features a rapid response thermostatic element for superior control. The thermostatic element senses the outlet water temperature and react to maintain a constant delivery temperature even under changing flows or variations in supply temperatures or pressures. It provides stable operation at flow rates as low as 0.25 gpm (1.0 l/min). The valve also reduces the outlet flow to a trickle in the event of a cold water supply failure.

The Heatguard® 135 features a threaded cover over a spindle mechanism that requires a special tool to adjust the temperature. The special tool is provided with each valve.

The Heatguard® 135 has inlet connections to suit a 3/8" flexible hose connector or a compression connection to 3/8" OD tube. Also available with cold water bypass and elbow insert fittings. Supplied standard with integral chech vlaves on both inlets to prevent cross-flow.
