OKECryogenicSolenoid ValveOverview

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

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

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

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

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

04. The coils are resistant to burning out.

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

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

07. Interface sizes typically comply with national or international standards; custom interfaces are available upon request.

08. The standard product lifespan exceeds 1.5 million cycles.

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

10. If the solenoid valve coil loses power or burns out, a manual handle can be used to open and close the valve.
