ZQDF Stainless steel solenoid valve Product introduction
ZQDF Stainless steel solenoid valve manufacturer, factory and supplier. ZQDF Stainless steel solenoid valve is composed of 304 or 316 stainless steel, ZQDF solenoid valve is mainly used for steam,tap water, distilled water, frozen brine, electroplating waste liquid and other liquid media, but also for viscosity less than 4°E oil. Steam solenoid valve.
ZQDF Stainless steel liquid solenoid valve is the industrial process automatic control system with the actuator, it can automatically open or close the valve after receiving the electronic control signal, to achieve the fluid medium in the pipeline on/off or flow control so as to the temperature, flow, pressure and other parameters in the automatic adjustment or remote control.
ZQDF Stainless steel solenoid valve be widely used in textile, printing, chemical, plastic, rubber, pharmaceutical, food, building materials, machinery, electrical appliances, surface treatment and other production and scientific research departments as well as bathroom, canteen, air conditioning and others.

ZQDF Stainless steel solenoid valve features:
1. Corrosion resistance: The main parts of the valve plug, valve body made of stainless steel and cast steel, corrosion resistance is good.
2. Heat resistance: electromagnetic and sealing parts are all made of special high temperature resistant electrical materials and sealing materials, and effective heat insulation measures are adopted.
3. Wear resistance: Material selection is reasonable, the fluid lubrication between the plug and the valve body is cleverly used to reduce wear.
4. Condensation resistance: the cold north water of the steam pipeline is an important factor
ZQDF stainless steel solenoid valve working principle:
ZQDF stainless steel solenoid valve for step action direct pilot solenoid valve, according to the power at the open, closed state of the different, can be divided into normally closed solenoid valve and normally open solenoid valve. When the coil is energized, the armature first drives the valve plug of the auxiliary valve to be lifted under the action of electromagnetic force, and the fluid on the valve cup of the main valve flows away through the auxiliary valve, reducing the pressure on the valve cup of the main valve. When the pressure on the valve cup of the main valve is reduced to a certain value, the armature drives the valve cup of the main valve, and makes the valve cup of the main valve open by means of pressure difference, and the medium circulates. When the coil is powered off, the electromagnetic force disappears and the armature resets due to its own weight. At the same time, depending on the medium pressure, the main and auxiliary valves can be closed tightly.
Normally open stainless steel solenoid valve, coil energized due to suction action, moving iron core down, the auxiliary valve plug down, auxiliary valve closed, the main valve cup pressure rises, when the pressure rises to a certain value, the upper and lower pressure difference of the main valve cup, due to the action of electromagnetic force, the moving iron core loses the main valve cup, pressure the main valve seat, the valve closed. Coil power, electromagnetic suction is zero, auxiliary valve plug and support core due to the action of spring up, auxiliary valve open, the fluid on the main valve cup flow through the auxiliary valve, reducing the effect of the pressure on the main valve cup, when the pressure on the main valve cup is reduced to a certain value, the use of differential pressure to push up the main valve cup, the main valve open, medium circulation.
