The 2W series flanged semi direct acting solenoid valve is an industrial grade universal automated fluid shut off valve designed for general process pipelines.To satisfy distinct fail safe operations and logical parameters of modern processing manifolds, this series is explicitly split into Normally Closed and Normally Open configurations. The Normally Closed configuration maintains a leak tight isolate position when de-energized and opens instantly when energized; conversely, the Normally Open configuration sustains an unobstructed flow path when de-energized and drives the internal core downward to isolate flow immediately upon electrical activation.The paramount technical attribute of this series is its semi direct acting structural design, which mechanically links the electromagnetic moving plunger directly to the self balancing main sealing assembly, combining the dual advantages of direct acting and pilot operated mechanisms.This linked layout allows both NC and NO configurations to completely eliminate the strict requirement of traditional pilot valves for a minimum system differential pressure, securing zero pressure drop lightweight startup and agile isolation even under gravity fed or low pressure states, while effectively overcoming the technical limitations of standard direct acting valves which suffer from insufficient driving force under large caliber high velocity fluid impacts.The valve body is available in three rugged material options, high density premium brass, precision cast stainless steel SS304, and heavy duty industrial cast iron, equipped with standard flanged connections for high rigidity pipelines.Powered by heavy duty electromagnetic coils and precision manufactured self balancing internal components, it performs reliably across a nominal pressure spectrum of zero to ten bar and operating temperatures from minus twenty to sixty five degrees Celsius, delivering dependable remote automated control and long term tight isolation for universal automated manifold systems and heavy industrial processing applications.

Dual Configuration Modes for System Fail Safe Versatility

Engineered into independent Normally Closed and Normally Open structural configurations to match different system logic setups, where NC configuration safeguards zero flow bypass during power outages while NO configuration maintains fully open venting paths under de-energized conditions.

Semi Direct Acting Mechanism for Zero Pressure Two Way Agile Startup

Whether operating in NO or NC configuration, the linked dual layer main valve design functions flawlessly under zero differential pressure or gravity fed conditions without requiring system pressure assistance, resolving the common low pressure failure modes of big caliber valves.

Universal Pressure Spectrum and High Flow Rates

The fluid dynamics optimized valve cavity and large internal flow paths significantly enhance the flow coefficient, providing extremely low flow resistance and stable isolation under low to medium pressure general industrial conditions for both configurations.

Broad Material Adaptability with Three Body Options

Available in high density premium brass, precision cast stainless steel SS304, and heavy duty industrial cast iron to resist varied harsh plant environments and satisfy distinct technical piping criteria.

Flanged Connection for High Strength Piping Integration

Spanning full sizes from DN15 to DN50, standard flange interfaces enhance structural piping stiffness and anti vibration features, completely preventing joint seepage caused by intense fluid shocks or high frequency cycling.

Heavy Duty Industrial Coil with State Specific Balanced Response

Equipped with heavy duty power coils and anti fatigue stainless steel springs, the millisecond switching speed guides the plunger upward for NC open cycles or downward for NO close cycles, ensuring outstanding continuous duty stability.
