OKECryogenicSolenoid ValveOverview

American OKE cryogenic solenoid valves are constructed with cryogenic and wear-resistant stainless steel for both the valve body and internal components. They are designed for various low-temperature applications, suitable for automatic control in pipelines handling liquid nitrogen, liquid ammonia, refrigeration, and more. The specially manufactured coils feature waterproof and explosion-proof characteristics, with rated voltages of DC12~127V or AC36~380V. Other voltages can be customized. These valves offer stable performance and extremely high reliability.

Widely used in industries such as petrochemicals, medical equipment, biopharmaceuticals, refrigeration and air conditioning, and food and beverages, they are the preferred choice for automation control engineering, project upgrades, and equipment matching in refrigeration pipeline systems for aerospace, shipbuilding, chemical, freezing equipment, and food and medical equipment.

01. The solenoid valve core is made of stainless steel with a piston structure, offering strong resistance to operational fatigue.

02. The piston ring design is scientifically advanced, manufactured with special materials to prevent jamming by impurities in the medium, ensuring high sealing performance and long service life.

03. The metal piston and metal valve chamber do not directly friction, preventing jamming, and the valve body can be installed in any direction.

04. The coil is resistant to burning out.

05. Reasonable sealing materials and structure provide better sealing performance.

06. After long periods of inactivity, the valve restarts with the same sensitivity.

07. Interface sizes generally comply with national or international standards, with custom interfaces available upon request.

08. The standard product lifespan exceeds 1.5 million cycles.

09. A solenoid valve featuring an outer sleeve-type sealing piston ring and a high-performance combined sealing piston ring.

10. In case of coil power loss or burnout, a manual handle can be used to open and close the solenoid valve.
