ASCO SCE SCG Series Solenoid Valve | SCG238F017 SCE238D009 SCG238F016 | 2/2 Way Pilot Operated Valve

The SCE and SCG Series Solenoid Valves, supplied by Chengyuan Hydraulic, are high-performance pilot-operated valves engineered to the rigorous technical standards of ASCO. Our range includes widely utilized models such as SCG238F017, SCE238D009, SCG238F016, and SCG238F018. These 2/2-way Normally Closed (NC) diaphragm valves are renowned for their high-frequency response and superior sealing performance in medium-to-high pressure fluid systems.

At Chengyuan, we guarantee 100% Drop-in Interchangeability with original ASCO units regarding mounting interfaces, orifice sizes, and electrical specifications. Every valve is subjected to 100% simulation load testing on our digital benches to ensure reliable switching performance and structural integrity under diverse pressure gradients.

Key Technical Advantages:

• Precision Pilot Diaphragm: Featuring a reinforced synthetic diaphragm, these valves achieve full opening even under low-pressure differentials. The internal flow path is CFD-optimized to minimize pressure drops and maximize system efficiency.

• High-Endurance Electromagnetic Coil: Equipped with Class F/H insulation, our coils offer excellent heat dissipation and surge resistance. Designed for continuous duty, they prevent burnout during long-term automation cycles.

• Vibration & Corrosion Resistance: Forged bodies and hardened internal components provide exceptional durability against hydraulic shocks. The robust construction effectively mitigates the “water hammer” effect, protecting the valve seat.

• Modular Serviceability: The solenoid and internal components are designed for easy access. Maintenance, such as coil replacement or internal cleaning, can be performed without disconnecting the valve from the piping, minimizing downtime.

Application Areas:

• Industrial Automation: Controlling the flow of hydraulic oil, water, or neutral gases.

• Washing & Environmental Systems: Flow control in large-scale industrial washers and water treatment plants.

• Food & Pharma Machinery: Executing high-frequency filling or bottling tasks (with stainless steel variants).

• Power & Energy: Auxiliary hydraulic circuits in transformer cooling systems or generator sets.

Expert Maintenance Tips:

• Filtration Standards: Solenoid valves are sensitive to debris. We recommend installing a 100-mesh filter upstream to prevent particles from clogging the pilot orifice, which could cause malfunctions.

• Voltage Stability: Ensure the supply voltage stays within ±10% of the rating. Low voltage may cause incomplete activation and noise, while overvoltage significantly shortens coil life.

• Installation Orientation: Verify that the fluid flow aligns with the arrow marked on the valve body. For optimal longevity, install the valve with the coil in a vertical upright position to prevent sediment accumulation.
