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 parameters of control. Features sensitive operation, simple wiring, high flow capacity, compact size and high regulation accuracy.
● Provides a pressure differential on both sides of the back pressure valve piping
● Prevents siphoning, Eliminates dosing variations caused by pressure fluctuations at the injection point
● Used together with pulse dampers to reduce water-hammer damage to the system
● Protects piping, elbows and fittings, reduces the impact of pressure fluctuations
● Delivers its full effect only when used with other line components such as pulse dampers
● Can be controlled remotely, can be controlled by computer, PLC control
● Sensitive operation, high precision
