Thermostatic three-way valve Termojet 1" male thread, kvs-1.6, temp - 35-60°C

The Termojet TMV132 thermostatic three-way valve is a passive mixing device with a built-in thermostatic element for domestic hot water systems and bathrooms. It maintains the mixed outlet water temperature in the range of 35–60°C with an accuracy of ±2°C. Connection GZ 1" (male thread), flow coefficient Kvs 1,6 m³/h, maximum static pressure — 10 bar. The valve requires no power supply and no maintenance throughout its entire service life.

Technical Specifications

Operating Principle

Hot water (from the boiler or water heater) and cold water are supplied to two separate inlets of the valve. The thermostatic element in the body automatically adjusts the mixing ratio — the outlet temperature is maintained within the set range with an accuracy of ±2°C. Scald protection: when cold water supply is lost, the thermostatic element instantly shuts off the hot water supply — water from the tap or shower will not become dangerously hot. A sealed cap locks the settings against unauthorized tampering.

Applications

• Domestic hot water (DHW). Direct connection between the water heater and the point of use — the outlet temperature will not exceed the set limit even when the water heater heats to 70°C.
• Showers and bathrooms. Protection against scalding during pressure fluctuations or temporary cold water shutoff in the network.
• Public and medical facilities. Sealing of the temperature limiter meets safety requirements for facilities with elevated risks.
• Solar DHW systems. Protection against overheated water in the solar collector circuit — on sunny days, collector temperatures can reach 80–90°C and above.
• DHW recirculation circuits. Maintaining the temperature above 55°C in the recirculation circuit prevents the growth of harmful microorganisms, while the water at the remote tap remains comfortably warm.

Advantages of Termojet TMV132

• GZ 1" thread — larger size for high-flow consumption points or multiple simultaneous consumers.
• Brass CW617N body — corrosion resistance, reliable durability.
• ±2°C accuracy — stable temperature without noticeable fluctuations.
• No power supply — passive operation with no additional costs and no dependence on electricity availability.
• A worthy replacement for imported thermostatic valves of the same size — standard thread, standard mounting dimensions.

TMV132 and Heat Pump

Heat pumps heat the water in the DHW storage to 55–60°C for sanitary protection against harmful microorganisms. The Termojet TMV132 valve (35–60°C series) mixes this water with cold water to a comfortable 42–45°C directly at the supply point — the user receives safe water, and the heat pump can operate in sanitary heating mode without risk to users.

Frequently Asked Questions

What is the difference between TMV132 and TMV122?
Both valves are the 35–60°C series with Kvs 1,6. The difference is in the connection thread: TMV122 has GZ 3/4", TMV132 has GZ 1". Choose according to the thread on your pipeline or DHW distribution manifold.

Does TMV132 require a servo drive?
No. A thermostatic valve is a passive device: the thermostatic element responds to temperature independently without power supply. If you need a valve for a servo drive for automated mixing — see the rotary mixing valves in the catalog.

A valve like this keeps the return line at or above 55 °C and protects the heat exchanger from condensate — for example in the hookup of the 15 kW Termojet Ignis Pro 15 Plus pellet boiler.
