ElectricGas RegulatorsConsists of a linear electric actuator and a low-resistance straight single-seat valve body; The actuator is an integrated electronic structure, 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, Achieves regulation of pressure and flow parameters. Features sensitive operation, simple wiring, high flow capacity, compact size and high regulation accuracy.
➣ Balanced double-piston design
➣ control high precision
➣ operated convenient
➣ Low maintenance cost, long maintenance interval, easy assembly and disassembly, simple seat seal inspection and few spare parts
Excellent control performance: Control high precision, fast response, good stability
➣ Can be controlled remotely, can be controlled by computer, PLC control
➣ Sensitive operation, high precision
