Direct Acting Explosion Proof Diaphragm Solenoid Valve-EX2W
Explosion-proof solenoid valve is a kind of automation equipment specially designed for flammable and explosive media and explosive hazardous places, suitable for automatic switching of pipeline media in these places. It can be water, liquid or gas media level, concentration, flow, measurement or discharge cycle for automatic control, to achieve two-position switching, to ensure the safe operation of the system.
The explosion-proof solenoid valve is suitable for media temperature below 80 ° C stainless steel, sealing materials for NBR, EPDM, FKM (VITON) and PTFE, the pressure range of 0 to 1.0 MPa (0 to 150 PSI), 12V brass coil, diaphragm-type structure, and support OEM custom. The interface size is 2 inches and the warranty is 1 year. Widely used in food and beverage, water and wastewater treatment, ultrapure water, desalination, chemical, textile, pharmaceutical, pulp and paper, mining, boiler and power industries.
- Model: EX2W
- Size Range:3/8”~2”
- Pressure Range: 0-1.0 MPa
- Material: Brass or Stainless Steel 304/316
Features
Explosion-proof automation device:Designed for flammable and explosive media and explosive hazardous places, to achieve automatic switching of media and safe operation of automation equipment.
Wide Diameter and Pressure Range: The solenoid valve offers diameters from 5mm to 200mm, suitable for different pipes. Standard pressure is 0.03-0.8Mpa, other models reach 0-1.6Mpa.
Versatile Media Compatibility: Suitable for air, water, low-viscosity liquids, oil, and flammable media. Other models handle steam. Temperature ranges from 0℃ to 135℃.
High Efficiency and Safety: Features high-frequency coil design, 12VA, 15VA, and 25VA power. Excellent sealing prevents coil burning, ensuring safe use, ideal for gas industries.
Direct-Lift Diaphragm： Opens from 0 bar, suitable for low-pressure systems. Provides high flow rate, ensuring efficient operation.
The working principle of direct-acting explosion-proof solenoid valve ：
Normally closed type: when energised, the solenoid coil generates sufficient electromagnetic force to lift the moving parts (such as core, stem, piston/seal, etc.) off the valve seat to open the solenoid valve; when energised, the spring force presses the moving parts onto the valve seat to close the solenoid valve.
Normally open type: the working principle is the opposite of the normally closed type, the moving parts are pressed onto the valve seat to close the solenoid valve when the supply voltage is applied, and the electromagnetic force lifts the moving parts to open the solenoid valve when the supply voltage is removed.

Applications:
Water and Wastewater Treatment: In water treatment facilities, explosion-proof solenoid valves control the flow of water, chemicals, and other substances. They manage the water treatment process to purify water and safely treat industrial wastewater in compliance with environmental standards.
Textile Industry：In textile manufacturing, explosion-proof solenoid valves control liquid media during dyeing and chemical treatment processes. They ensure precise dosing and mixing of dyes and chemicals, thereby ensuring color consistency and quality in textiles.
The Chemical Industry: The chemical industry handles and produces chemicals. Explosion-proof solenoid valves control the flow of liquids. They are made from materials that don’t rust and keep chemical plants safe and efficient.
Food and Drink: Explosion-proof solenoid valves control liquid media (e.g. water, syrups, juices) on production lines in food and beverage production. These valves control liquid flow during food production.
Pharmaceutical and pulp and paper industries: These industries use explosion-proof solenoid valves to control liquid media in chemical processes.
Explosion-proof solenoid valves are essential components designed to safely regulate the flow of liquids or gases in environments with flammable materials, thereby preventing potential explosions or accidents. The impact of explosion-proof solenoid valves is felt across a number of industrial sectors, including food processing, water treatment, chemicals and pharmaceuticals. In these fields, they play an essential role in ensuring operational safety and compliance with rigorous safety standards, thereby contributing to the overall safety and efficiency of the modern workplace.
