Thermostatic three-way valve Termojet 1" male thread, kvs-2.5, temp - 35-60°C

The Termojet TMV232 thermostatic three-way valve is a passive mixing device with an increased flow coefficient for domestic hot water systems with higher consumption. It maintains the mixed water temperature in the range of 35–60°C with an accuracy of ±2°C. Connection GZ 1" (male thread), flow coefficient Kvs 2,5 m³/h, maximum static pressure — 10 bar. The increased Kvs 2,5 allows simultaneous service of multiple draw-off points without pressure drop.

Technical Specifications

Operating Principle

Hot water from the boiler or storage heater and cold mains water enter through two separate inlets. The built-in thermostatic element automatically regulates the mixing ratio — the outlet temperature is maintained within the set range with an accuracy of ±2°C without any power supply. Scald protection: if cold water fails, the thermostatic element blocks the hot flow — the outlet water remains safe. Kvs 2,5 provides higher flow capacity compared to Kvs 1,6 — lower hydraulic resistance at high consumption.

Applications

• Multiple DHW draw-off points. Kvs 2,5 allows simultaneous supply to shower, washbasin and kitchen tap without a noticeable pressure drop — ideal for homes with 2–3 bathrooms.
• Hotels and guest houses. A central anti-scald valve on the DHW riser — a single device protects all rooms on the floor simultaneously.
• Hospitals and social care facilities. Increased Kvs and sealed cap meet the requirements for simultaneous water draw-off and safety.
• Solar DHW systems with a large tank. When connecting a large thermal storage tank with potential heating up to 80–90°C — the TMV232 handles the increased flow without restrictions.
• Replacement of a Kvs 1,6 valve during system upgrade. If insufficient pressure is observed with the installed TMV132 (Kvs 1,6) — TMV232 with the same GZ 1" thread is installed as a direct replacement.

Advantages of Termojet TMV232

• Kvs 2,5 — higher flow capacity in the same GZ 1" size: lower hydraulic resistance, less pressure drop when several taps are opened simultaneously.
• Brass body CW617N — corrosion resistance and long service life.
• Accuracy ±2°C — stable temperature regardless of pressure fluctuations in the network.
• No power supply required — passive reliable operation without additional automation.
• A worthy replacement for imported thermostatic valves of the same size and Kvs — standard thread, no pipe modification required.

TMV232 and the Heat Pump

Heat pumps heat the DHW cylinder to 55–60°C in sanitary protection mode. For homes with high water consumption, the Termojet TMV232 valve with Kvs 2,5 ensures sufficient flow to all draw-off points without pressure drop — even when all family members open the hot water simultaneously.

Frequently Asked Questions

When to choose Kvs 2,5 instead of Kvs 1,6?
Kvs 1,6 is sufficient for a single bathroom or low consumption volume. Choose Kvs 2,5 when 2–3 draw-off points operate simultaneously, with elevated system pressure, or to reduce hydraulic resistance in a branched DHW circuit.

Is the TMV232 compatible with a DHW recirculation pump?
Yes. The valve is installed on the hot water supply after the cylinder; the recirculation circuit is connected separately to the DHW return pipe. If you are interested in a complete DHW scheme — see the Termojet valve catalogue.
