Motorised back pressure valve ETY72

Motorised back pressure valve ETY72(electric control, gas, O2): Motorized Back Pressure Valves, For stainless Steel Back Pressure Valves, choose SHZDH, 12 years of industry experience in pressure regulating valves, Serves top-500 enterprises, Designed and developed by senior engineers, Customization available for special service conditions.

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.
