Electrical proportional valveGas RegulatorsAdjusts downstream pressure according to the control electric signal, controlling the downstream fluid pressure. Pressure can be set anywhere within the adjusting range, continuous control, achieving continuous, stepless downstream pressure regulation, supports remote, program, computer and PLC control, for applications requiring remote and precise pressure control, Electric proportional gas regulators are especially suitable.
