The ASCO Series 238 is a pilot-operated general service solenoid valve designed for high-flow liquid and gas control in industrial systems. Engineered with a floating diaphragm design, it uses line pressure to assist valve operation, allowing for efficient control of larger flows with lower power consumption.
Unlike direct-acting valves, the Series 238 is optimized for applications where adequate differential pressure is available, making it ideal for water, air, inert gas, and light oil service.
Its robust construction and proven solenoid technology make it a trusted choice for OEM equipment, process automation, and utility systems requiring dependable shutoff and flow control.
Best suited for:
- High-flow fluid control systems
- Industrial process lines
- Water and utility management
- OEM and skid-mounted equipment
