OKE Ammonia Solenoid ValveOverview

Imported ammonia solenoid valves are used in various normal temperature, normal pressure, and low-pressure applications, suitable for handling corrosive media or media with particles. They are widely used in industries such as testing equipment, medical devices, pharmaceuticals, electroplating and coating, cleaning equipment, and agricultural machinery, serving as essential components for automated chemical fluid production equipment.

Normally Closed: When the coil is energized, the pilot valve core is attracted, the pilot hole opens, the upper valve chamber depressurizes, and the piston is pushed by the medium pressure in the lower chamber, opening the solenoid valve. When the coil is de-energized, the pilot valve core resets via the spring, the pilot hole closes, and the valve chamber pressurizes through the piston throttle hole and the reset spring's thrust, closing the solenoid valve.

OKEAmmoniaSolenoid ValveFeatures

1. Special on-site installation is required; please inform specific working conditions before ordering.
2. Excellent corrosion resistance, inert to all common chemicals.
3. Outstanding heat resistance, capable of long-term operation at 230~260°C.
4. Different polymer materials are selected based on the chemical medium, enhancing usage rationality.
5. Pilot and depressurization holes are dozens of times larger than those of traditional valves, with the reset spring located outside the starvation zone.
6. Resistant to clogging, acids, alkalis, and corrosion, with a long service life.
