Solenoid shut-off valve EV220B 20B NC, G 3/4 inch, 0.3-16 bar, Kv 8m3/h, brass/EPDM, without coil, PZH and CNBOP certified 032U7120

Universal solenoid valve for various applications

This EV220B shut-off solenoid valve is a versatile 2/2-way valve with servo-assistance, designed to control the flow of liquids and gases in a wide range of installations. Made of brass with an EPDM seal, it ensures reliable operation even in harsh conditions. This valve is particularly valued for its adjustable closing time and built-in internal filter that protects the pilot system from contamination.

The EV220B valve finds application in irrigation systems, fire protection equipment, drinking water installations, and in industry – from technological washing systems to dental equipment and wind turbines. Its versatility makes it an ideal choice for both professional installers and end-users.

Design and operating parameters

The valve body made of brass guarantees durability and corrosion resistance. The EPDM seal ensures tightness and allows operation with media at temperatures up to 120°C. The valve is characterized by a flow rate Kv of 8 m³/h and can operate in a pressure range from 0.3 to 16 bar. The minimum differential pressure required for proper operation is 0.3 bar. This ensures stable operation under various hydraulic conditions.

The use of characteristic C allows for a delayed reaction to short-term current surges, which is particularly important when starting devices with motors – this protects the installation from unnecessary tripping. Additionally, the valve has protection against hydraulic shock, which increases its lifespan and reliability.

Features and benefits

• Versatility: Possibility of use in various media (liquids, gases) and industrial and domestic installations.
• Durability: Made of high-quality brass ensures long-term operation.
• Protection: Built-in internal filter protects the pilot system from contamination, and protection against hydraulic shock protects the valve from damage.
• Flexibility: Adjustable closing time allows you to adapt the valve's operation to the specific needs of the installation.
• Safety: The valve has PZH and CNBOP approvals, confirming its compliance with applicable norms and safety standards.
• Easy installation: Standard G 3/4 inch thread facilitates integration of the valve with existing hydraulic infrastructure.
• Wide pressure range: Operation in the range of 0.3 to 16 bar allows the valve to be used in various systems with varying working pressure.
• Media resistance: The EPDM seal allows operation with negative temperature glycol and low-pressure steam at temperatures up to 120°C.

The EV220B valve is supplied without a coil – which allows you to choose the appropriate control voltage and IP protection class according to the requirements of a specific application. Remember to select the appropriate coil!
