BLDCF type proportional solenoid valve
(Applied to pressurizer spray system)
Product Overview:
Cone force and the electromagnetic valve mentioned above are valves that use electromagnetic force to drive signals for flow or pressure regulation. They have many advantages such as fast action, no leakage, small size, and convenience
The proportional solenoid valve adopts a shielded proportional solenoid as the actuator, and the valve core adopts an internal pressure feedback structure. The position of the valve core is detected by a shielded continuous position indicator device and fed back to the intelligent control device. The combination of proportional electromagnet, internal pressure feedback regulating valve core, precise position indicator device and intelligent control device improves the adjustment accuracy
function
When the pressure of the stabilizer increases, the proportional solenoid valve opens according to the pressure control signal of the stabilizer, and sprays water with relatively low temperature into the stabilizer. The higher the pressure in the water, the greater the valve opening and flow rate, until the system pressure is reduced to normal operating level. It automatically closes according to the pressure automatic signal.
