ZCLD type ultra-low temperature solenoid valveDetailed product description：

ZCLD type straight through ultra-low temperature solenoid valve is powered by AC or DC power supply, used to connect or cut off the flow of medium in the pipeline. This valve can be used to control the flow of liquid nitrogen, liquid oxygen (requiring degreasing treatment) or other -196 ℃ media in pipelines. The valve has sensitive action and reliable performance, and is highly welcomed and praised by users.

ZCLD type ultra-low temperature solenoid valve can customize the size of the constant temperature rod according to user requirements and does not require the installation of a flange.

The specific technical parameters of the valve are as follows:
ZCLD type ultra-low temperature solenoid valve nominal diameter: DN3~DN25;
Nominal pressure: 0~1.6Mpa
Medium: liquid nitrogen, liquid oxygen
Temperature: -196 ℃
Voltage: AC220V, 380V, DC24V
Material: Stainless steel
Control mode: normally closed, normally open, explosion-proof

Working principle of ZCLD type ultra-low temperature solenoid valve: This series of solenoid valves is a direct acting automatic valve. When not powered, the main valve port is closed due to the weight of the movable iron core and the force of the spring. When the solenoid valve coil is energized, the coil excitation circuit forms a magnetic field and generates magnetic force. The movable iron core is attracted by the electromagnetic force, overcomes its own weight and the resistance of the spring, and rises, driving the valve stem to move upward and directly open the main valve port, forming a passage; After power failure, the movable iron core moves downward under the action of spring force, and the valve stem is subjected to downward pressure to close the main valve port, causing the valve port to cut off flow. The solenoid valve is in a closed state (the opposite is true for normally open valves).
