OKECryogenicSolenoid ValveOverview

OKE cryogenic solenoid valves from the United States feature valve bodies and internal components made of low-temperature, wear-resistant stainless steel, designed for various cryogenic applications. They are suitable for automatic control in pipelines handling liquid nitrogen, liquid ammonia, refrigeration, and more. The specially designed coils are waterproof and explosion-proof, 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 integration in aerospace, shipbuilding, chemical, refrigeration equipment, and food and medical equipment pipeline systems.

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, made from special materials that 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 rub against each other, 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 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 both 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 valve.

OKECryogenicSolenoid ValveFeatures

1. Treated with deep cryogenic processing, capable of withstanding temperatures as low as -200°C.

2. Ultra-long lifespan, stable performance, excellent sealing, and rapid switching.

3. Unique design with an elegant appearance; piston structure ensures stable performance; cryogenic materials and sealing coils are resistant to burnout.

4. The valve core is made of stainless steel piston type; the piston ring is crafted from special low-temperature and wear-resistant materials. The piston does not directly friction with the metal valve chamber, allowing unlimited installation directions. The specially designed coil is resistant to burnout. After prolonged inactivity, it restarts with the same sensitivity.
