Zbsf-25 stainless steel solenoid valve

  Application zbxy series stainless steel solenoid valve is an actuator used in industrial process automation control system
It can automatically open or close after receiving the electric control signal, and realize the on-off or flow regulation control of the liquid medium in the pipeline

Piston solenoid valve can be widely used in production and scientific research departments such as textile, printing, chemical, plastic, rubber, pharmaceutical, food, building materials, machinery, electrical appliances, surface treatment, as well as people's daily living facilities such as bathrooms, canteens, air conditioners, etc
Zbxy-y series solenoid valves are mainly used to control corrosive liquid, ultra clean liquid, edible liquid and other liquid media
Zbxy series solenoid valves are mainly used to control corrosive gas, ultra clean gas and other gas media

Model and specification of piston solenoid valve
Main features of piston solenoid valve
Corrosion resistance: most parts are made of stainless steel or cast stainless steel, with good corrosion resistance

Heat resistance: special high-temperature resistant electrical materials and sealing materials are used for the electromagnetic parts and seals, and effective heat insulation measures are adopted

Wear resistance: the material selection is reasonable
The fluid lubrication is cleverly used between the valve cup and the guide sleeve to reduce wear

Reliable: the structure is simple and compact
It combines the advantages of direct acting and pilot indirect solenoid valves, and can work reliably under the condition of low pressure difference or zero pressure difference

Structure principle of steam solenoid valve
This valve is a piston type solenoid valve, which can be divided into normally closed solenoid valve and normally open solenoid valve according to the different switching states when power is off
Normally closed solenoid valve: after the coil is energized, the armature will first drive the auxiliary valve to open under the action of electromagnetic force, and the main valve will open under the action of the formed medium pressure difference and electromagnetic force
The coil is powered off, the armature part is reset, and the main and auxiliary valves are tightly closed by using the medium pressure

Normally open solenoid valve
After the coil is energized, the armature moves down under the action of magnetic force, pushing the auxiliary valve plug down until it is compressed with the auxiliary valve seat, and the auxiliary valve is closed
As the pressure difference between the upper and lower parts of the main valve cup tends to be equal, the main valve cup is tightly compressed by magnetic force and self weight, and the valve is closed
The coil is powered off, the magnetic force is zero, the armature and the auxiliary valve plug are raised by the spring, the auxiliary valve is opened, the medium in the main valve cup flows away through the auxiliary valve, the pressure drops, the main valve cup is raised by the lower and lower differential pressure, the main valve is opened, and the valve is opened
