Mixing and shunt shut-off valves
MOTOR-DRIVEN 3-WAY DEVIATING AND MIXING PN 16 SHUTTER VALVES
The VPR series of 3-way shutter valves may be used as deviating or mixing valves (water, water + max. 30% glycol) in heating, conditioning and ventilating systems.
They may be motor-driven with MUT motors series V3, on-off and modulating. The VPR valve is available in two versions: - N.O. (normally open): if the stem of the valve is not pressed, the direct passage (AB-A) is open and the by-pass (AB-B) is closed. - N.C. (normally closed ): if the stem of the valve is not pressed, the direct passage (AB-B) is open and the by-pass (AB-A) is closed. VPR valves present:
- High Kvs values.
- Possibility of precise modulation thanks to the long travel and shape of the shutter, which allows both the direct passage and the by-pass to be opened immediately, guaranteeing a modulation of the flows in a field equal to the whole travel.
- Very low leakage, even if used in systems with a high differential pressure.
The valves are particularly suitable for use in regulating temperature in underfloor heating systems.Download
