Solenoid Valve
This Solenoid Valve is a two-way flanged modulating control valve with magnetic actuator, PN16, DN15~DN50. It is designed for regulating hot water and saturated steam flow in HVAC systems. It accepts 0/2…10V or 0/4…20mA control signal with position feedback, features spring return (fail-close), built-in manual override and fast response. Compact integrated structure, compliant with European EN standards, CE approved.
