The DN20 - 3/4" mixing valve HVTC-90" is controlled by a thermostatic actuator by which the temperature to be maintained constant in the flow is set.
The valve is supplied with 2 by-passes: - by upper by-pass (system side): it takes part of the system return water and flows it into the flow, allowing heat recovery and temperature balancing in radiant panel systems. - by lower by-pass (boiler side):it allows the bypassing of the flow water in presence of the pump in the boiler and no hydraulic separator.
Plus / Advantages:
- 3-way mixing valve controlled by a thermostatic actuatorl - Easy to change the flow from right to left - 2 by pass integrated
