Asco 8222G47 Pilot-Operated Piston Valve 1/2" NPT Normally Closed

The Asco 8222G47 is a high-temperature pilot-operated piston valve designed for demanding steam and hot water applications. This Y-body floating piston design delivers reliable performance in harsh industrial environments, making it ideal for commercial laundry equipment, sterilizers, autoclaves, steam atomization systems, and molding operations.

Key Features:

• Steam service rated up to 125 PSI differential pressure at 355°F
• Hot water service to 150 PSI at 210°F
• 1/2" x 1/2" NPT pipe connections for easy installation
• Normally closed operation—valve closes when de-energized for fail-safe control
• Self-aligning piston resists sticking and reduces maintenance needs
• Durable construction with stainless steel core tube and springs
• Two-way valve configuration for versatile flow control

The pilot-operated design uses line pressure to actuate the main valve, allowing for efficient operation with minimal energy consumption. The Y-body floating piston construction provides exceptional durability and reliability in high-cycling applications. This valve is engineered to withstand the thermal stress and corrosive conditions commonly found in steam service environments, ensuring long service life and dependable performance.
