Motor-Driven 3-Way Deviating and Mixing PN16 Shutter Valves Series VPR
PRINCIPAL CHARACTERISTICS AND APPLICATIONS : 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 system of the valve is not pressed, the direct passage (AB-A) is open and the by - pass (AB-b) is closed. - N.C. (normally close): 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 valves. |
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 system with a high differential pressure. The valves are particularly suitable for use in regulating temperature in underfloor heating systems. |
