The motorised back pressure valve consists of a linear electric actuator and a low-resistance straight-through single-seat valve body. The electric actuator has an integrated electronic design, with built-in servo amplifier, remote control possible, computer control, a control signal (4-20mA DC or 0-5VDC) plus the power supply sets the valve opening. Reach for pressure, flow rate etc. Operating conditions parameters of control. Features sensitive operation, simple wiring, high flow capacity, compact size and high regulation accuracy
