ASCO Solenoid Valve w Flexible Tubing and Fittings

ASCO General Service Pilot-Operated Solenoid Valve Kit – 120V AC, 6.3W Coil, 5–230 PSI Operating Pressure, Includes Flexible Tubing and Fittings (MPN: WPSC8238T402)

The ASCO WPSC8238T402 is an industrial-grade, high-performance 2-way pilot-operated solenoid valve kit engineered for precise, responsive fluid control in commercial, laboratory, and automated industrial environments. Operating as part of ASCO’s trusted 8238/238 general service platform, this compact valve handles a broad spectrum of compatible media including air, inert gas, water, and light oils. Driven by an efficient 120V AC (60 Hz) coil drawing just 6.3 watts, the system functions within a dynamic operating differential pressure range of 5 to 230 PSI. Designed as a versatile plumbing solution, the WPSC8238T402 comes bundled with a specialized assortment of flexible companion tubing and fluid fittings, enabling immediate, drop-in integration into complex liquid routing grids or pneumatic control networks.

Technical Performance and Design

• Proven 8238 Series Compact Architecture: Developed with minimized pressure vessel walls and optimized coil windings. The space-saving structural profile reduces physical installation time, simplifies localized tool maintenance, and increases overall deployment flexibility inside tight equipment bays.

• Efficient Pilot-Operated Short Stroke: Utilizes a floating diaphragm pilot mechanism that leverages inline fluid backpressure to assist valve actuation. The shortened stroke profile minimizes internal friction and component wear, drastically increasing physical cycle life compared to traditional direct-acting valves.

• Watertight Connector Interface: Outfitted with a premium, water-resistant right-angle electrical connector. This standardized configuration isolates line-voltage wiring connections from cleanroom spray-downs, humidity, or ambient chemical vapors without requiring bulky auxiliary junction boxes.

• Rugged Brass Body Material Matrix: Machined from high-density, passivated brass alloy paired with stainless steel internal springs, core tubes, and plugnuts. This core composition delivers excellent structural durability, zero outgassing, and long-term scaling resistance.

Key Benefits and Applications

• Automated Process Equipment Controls: Frequently deployed across life sciences setups, commercial laundry arrays, packaging lines, and industrial HVAC hydronic loops for quick on/off line isolation.

• Laboratory Gas Purging Manifolds: Serves as an excellent automated gas control valve to safely pulse cleanroom nitrogen or utility compressed air feed line cycles into environmental testing chambers.

• Water and Wastewater Management: The pilot-operated floating diaphragm handle handles continuous liquid flow profiles seamlessly, resisting premature water-hammer shock degradation.

• Streamlined Fluid Kit Integration: The inclusion of high-quality tubing and matched thread-to-barb fittings cuts down on plumbing sourcing time, allowing technicians to complete quick, tool-secure bench assemblies without thread mating issues.
