Product Description

Norgren VCB22B517A-AB219L

The Norgren VCB22B517A-AB219L is a high-performance 2/2-way angle seat valve designed for robust process control in various industrial applications. It features a durable bronze body and PTFE seals, ensuring compatibility with a wide range of media including steam, water, air, and other neutral or aggressive fluids (subject to compatibility checks). This normally closed valve is actuated by a 50mm polyamide actuator and controlled by an integrated 24V DC solenoid pilot valve (Norgren’s AB219L specification), which includes an LED indicator for operational status. With G3/4 (BSPP) threaded connections, it offers reliable sealing and easy installation. The VCB series is known for its high flow rates and long service life, making it suitable for demanding on/off applications.
