Ridutive three -way pressure proportional valve the piloted PZME3 are proportional valves of reduced three -way pressure, piloted, in a modular version. They are used to reduce pressure in the secondary circuit branches ensuring the stability of the pressure regulated also when varying the flow that crosses the valve. They are available in three pressure decreases up to 230 bar. PZME3 can be controlled directly with a controlled power supply in current, or with an electronic card to be ordered separately.
