OKE Solenoid ValveWorking Principle

Normally Closed: When the coil is energized, the electromagnetic core attracts, opening the pressure relief hole. The main diaphragm is pushed by the medium pressure, opening the main valve port to allow medium flow.

When the coil is de-energized, the main valve port closes, stopping the medium flow.

OKELiquidSolenoid ValveOverview

Imported flange solenoid valves are actuators used in industrial process automation control systems. Upon receiving an electrical control signal, they automatically open or close the valve to control the on/off or flow regulation of fluid media in pipelines, thereby automatically adjusting or remotely controlling parameters such as temperature, flow, and pressure within the system.
Suitable for media such as air, water, and oil, they perform two-position on/off switching for automatic control of liquid level, concentration, flow, metering, or discharge cycles. The solenoid direct-acting valve opening structure allows zero pressure differential opening. Diaphragm-type sealing ensures sensitive operation and reliable opening and closing.

OKELiquidSolenoid ValveFeatures

Corrosion Resistance: Most components are made of stainless steel or cast stainless steel, providing excellent anti-corrosion performance.
Heat Resistance: The electromagnetic parts and seals are made of special high-temperature-resistant electrical materials and sealing materials, with effective thermal insulation measures.
Wear Resistance: Rational material selection and clever use of fluid lubrication between the valve cup and guide sleeve reduce wear.
Reliability: Simple and compact structure, combining the advantages of direct-acting and pilot indirect solenoid valves, ensuring reliable operation even under low or zero pressure differential conditions.
