Asco 8222G94 1/2" x 5/8" Pilot-Operated Piston Valve Normally Closed

The Asco 8222G94 is a pilot-operated piston valve designed for reliable control of air, water, oil, and other compatible fluids in industrial applications. This normally closed valve features 1/2" inlet and 5/8" outlet port connections, providing precise flow control with minimal pressure drop.

Key Features:

• Pilot-operated piston design for efficient operation with high flow capacity
• Normally closed configuration - valve closes when de-energized for fail-safe operation
• 1/2" x 5/8" port sizes accommodate various piping requirements
• Durable construction suitable for demanding industrial environments
• Compatible with air, water, light oils, and neutral gases
• Low power consumption through pilot-operated mechanism

Pilot-operated valves use system pressure to assist in opening and closing, allowing for larger port sizes and higher flow rates while maintaining compact actuator dimensions. The normally closed design ensures the valve returns to a safe closed position during power loss or system shutdown, making it ideal for process control, pneumatic systems, and fluid handling applications.
