Burkert 2 Port Normally Closed Solenoid Valve DN 10 to 65 mm, Stainless Steel Brass Nickel Plated, 110V AC, 10 bar 221756

Burkert 221756 is a premium 2 Port Normally Closed (NC) Solenoid Valve designed for precise fluid and gas control in diverse industrial applications. It operates with a 110V AC power supply and features inlet port sizes ranging from DN 10 to 65 mm, making it adaptable to various piping specifications.

The valve body is constructed from corrosion-resistant materials including stainless steel, brass, and nickel-plated brass, ensuring durability and longevity under demanding conditions. This valve is part of the Series 221 range, known for its reliable performance in vacuum and compressed air systems.

Engineered for industrial use, the valve supports a maximum operating pressure of 10 bar and withstands temperatures from -30°C to +120°C. It incorporates servo-assist technology, which facilitates smooth piston operation and noise-free, water hammer-resistant flow control, crucial for maintaining system integrity.

Featuring a 40 mm orifice diameter and flow factor Kv 30m³/h, the valve offers a high flow rate for efficient system performance. The valve opens without differential pressure, with a minimum pressure differential of 0.5 bar required for full opening, ensuring flexible control in various scenarios. The maximum opening and closing times are 4 seconds each, enabling timely valve actuation.

Its IP65-rated coil housing protects against dust and water ingress, extending the operational reliability in harsh environments. Additionally, the valve holds explosion protection certification for intrinsically safe operations (Ex-i), permitting use in hazardous and explosive atmospheres.

Compact dimensions facilitate installation in confined spaces, advantageous for applications in heating and refrigeration systems, water treatment plants, swimming pool technology, and other fluid handling industrial setups. Due to its internal design complexity, the valve must be used with clean neutral media to avoid operational issues. The electrical connector for the valve is available separately.

Overall, Burkert 221756 delivers robust performance, versatility, and reliability for industrial fluid control tasks requiring precise valve actuation under varying pressure and temperature conditions.

Manufactured from stainless steel, brass, and nickel-plated brass for durability. Operates up to 10 bar pressure with temperature tolerance from -30°C to +120°C. Includes servo assist for smooth piston movement and water hammer reduction.
