Description
Watson McDaniel HB Series — 2-Way Control Valve with Electric Actuator (EC & ES) for Steam, Air & Water
The HB Series electrically-operated 2-Way Control Valve is a high-performance stainless-steel valve designed for accurate modulation of steam, air, and water. Built with Class IV shut-off capability and available in sizes from 1/2″ to 4″, the HB Series delivers precise flow control in industrial and process applications. When paired with Watson McDaniel EC or ES electric actuators, the HB Series provides smooth, reliable operation with options for super-capacitor fail-close (EC) or spring-return fail-safe (ES).
