ZBSF flange stainless steel solenoid valve DN15-500mm

Shanghai Zhen ZBSF series stainless steel solenoid valve uses: ZBSF series stainless steel solenoid valves for industrial process automation control system used in actuators. It can automatically turn on or off after receiving electrical control signal, to achieve continuity or flow pipeline regulatory control of the liquid medium. Steam solenoid valve can be widely used in textiles, printing, chemicals, plastics, rubber, pharmaceutical, food, building materials, machinery, electronics, surface treatment and other production and scientific research departments as well as bathrooms, dining room, air conditioning and other facilities of daily life. ZBSF-Y series solenoid valve is mainly used to control the corrosive liquids, clean liquids and edible liquids and other liquid media. ZBSF series solenoid valve is mainly used to control the etching gas, clean gas and other gaseous medium. Steam solenoid valve Model specifications: Corrosion: most of the parts are made of stainless steel or cast stainless steel, corrosion resistance is good. Heat: electromagnetic part, seal all using special high temperature electrical materials and sealing materials, and the use of effective insulation measures. Wear: selection and reasonable guidance suite valve cup and clever use of fluid lubrication, reducing wear and tear. Reliable: simple and compact structure, combines the advantages of direct-acting solenoid valve and pilot indirectly, in the case of low pressure difference or differential pressure of zero can reliably. Steam solenoid valve principle structure: The valve is a step by step action direct pilot solenoid valve, which switches different states based on when power can be divided into a normally closed solenoid valve and a normally open solenoid valve. Normally closed solenoid valve, the coil is energized the armature electromagnetic force to drive the secondary valve work started, the main valve in the role of media pressure and electromagnetic force formed and open. Coil power, the armature assembly is reset, the primary and secondary valve with a medium pressure and tight shut off. Normally open solenoid valve, the coil is energized, the armature magnetic force down, push the auxiliary valve spool down until the seat and the deputy pressed, vice valve is closed, since the main valve cup up and down pressure tend to be equal, the main Cover valve cup tightly pressed by the force and weight, the valve closes. Coil power, the magnetic force is zero, the armature and the secondary valve spool up from a spring, the Deputy valve is opened, the main valve cup medium flow away through the secondary valve, the pressure drops, the main valve cup by the action under pressure to rise From the main valve is opened, the valve opens.
