Applications:
SVC series of chemical corrosion solenoid valve with PTFE, UPVC, ABS three, sealing material Viton or PTFE, isolation media and other accessories, to meet different levels of acid corrosion and organic solvents, widely used in petrochemical, power equipment, pharmaceutical machinery, chemical Reagent, chemical analysis equipment, sewage treatment equipment, scientific instruments, etc., especially for serious corrosion, high temperature and chemical environment does not allow contact with the lubricant.
Technical parameters:
Principle structure: the floating piston-type
Medium: hydrochloric acid, sulfuric acid, alkali and other gases and liquids and organic solvents, etc.
Action: reliable, noise, power consumption of 50% for similar products
Electrical connection: terminal box, cable-lead
Protection class: DIN DIN40050 (IP65)
Explosion-proof grade: ExdIICT5
Operating factor: 100% ED
How it works:
1.step direct-acting:
   Normally closed type: solenoid valve, solenoid coil electromagnetic force generated from the seat to lift the pieces off, valve open; power, the electromagnetic force disappears, the spring force to close the piece down on the seat, the valve closes.
Normally open type: normally closed operation with the opposite direction.
2.Pilot:
   Normally Closed: When the solenoid coil is energized, the electromagnetic force open the pilot hole. The pressure chamber on the rapid decline in the vicinity of the piston and seals on the formation of a high pressure low. This pressure difference push the piston and seals from the valve seat on the lift. Valve opening; coil energized, the spring force pilot hole closed, the bypass valve inlet pressure into the hole on the chamber quickly, in the vicinity of the piston and seals compete on the formation of a low pressure difference, thus promoting the piston and seals pressing down on the seat, the valve closes.
Normally open type: normally closed operation with the opposite direction.

Selection guide:
1.fluid medium pressure, temperature and other parameters must be provided according to the actual working conditions.
2.If the fluid contains impurities, the solenoid valve should be installed in front of the filter (filter ≥ 60 mesh), and the fluid should be no solidification or crystallization.
3.Explosion-proof solenoid valve with no single, dual coil sub.
