The merging of an automatic balancing valve and a 2-way control valve into a single body has resulted in the pressure-independent 2-way control valve Optima Compact. The pressure-independent 2-way control valves Optima Compact / Optima Compact Flange are threaded / flanged fittings designed primarily for adjusting flows in end devices (fan coils, cooling beams, etc.) as well as flows in large technological networks, always ensuring precise performance regulation. The setting of the flow limiter in Optima Compact valves DOES NOT affect the working stroke of the control cone, which is therefore ALWAYS 2.5mm, 5mm, 5.5mm, and 15mm (Optima Compact), 20mm, and 40mm (Optima Compact Flange). We equip the pressure-independent 2-way control valves Optima Compact with thermal or electromechanical actuators, allowing us to choose the type of characteristic (linear / equal percentage) through this selection. Functions - Setting the desired flow - Flow regulation by the appliance (after fitting the control actuator) - Closing
