Burkert Stainless Steel 2-Port Normally Closed Solenoid Valve DN 10 to 65 mm, 24V DC, 10 Bar Operating Pressure 227557

Burkert 227557 Stainless Steel Solenoid Valve is a precision engineered 2-port normally closed valve designed for fluid power and industrial applications. Operating at 24V DC and supporting a maximum operating pressure of 10 bar, this valve is suitable for liquid, inert liquids, and gases including water treatment and swimming pool technology.

Constructed from durable stainless steel, the valve provides excellent corrosion resistance and mechanical strength. The soft mechanical coupling between the main piston and pilot armature ensures smooth operation with reduced noise and water hammer effects. Its compact size facilitates installation in restricted spaces.

The sealed coil is IP65 rated and offers excellent protection against dust and water ingress, ensuring reliable operation even in harsh environments. The valve includes servo assist technology, which enables opening without differential pressure and supports a fast response time between 0.1 to 4 seconds.

This valve is certified for explosion protection with intrinsic safety (Ex-i) enabling safe use in hazardous industrial areas. A minimum pressure differential of 0.5 bar is required for full opening, with a flow factor Kv of 30 m³/h to accommodate high flow demand. The operational temperature range extends from 0°C up to 120°C.

Typical applications include compressed air and vacuum systems, heating and refrigeration, water treatment plants, and swimming pool technology. Due to internal complexity, the valve is to be used only with clean neutral media for optimal performance and longevity.

Manufactured from stainless steel providing durability and corrosion resistance. Supports high flow rates with a 40 mm orifice diameter and Kv of 30 m³/h. Features IP65 sealed coil for protection against environmental factors.
