Reliability Research on Design of Oil-gas Multi-channel Control Valve

Multi-channel control valve of oil and gas is important to perform multi fuel flow control devices, which mainly used to control the oil flow through the pipeline entering the engine. It has four in-line solenoid valve and two check valve respectively connectted the fuel valve and oil drain valve connectors, which belongs to the directional control valves. In order to ensure operational reliability, this paper analyzed its working principle, structure design.
