ASCO 8221G13 Solenoid Valve

The ASCO 8221G13 Solenoid Valve is a high-performance, 2-way normally closed solution engineered specifically for industrial water service and HVACR applications. This pilot-operated valve features a unique slow-closing mechanism with a built-in snubber that effectively reduces the disc closing speed. This advanced design is critical for water hammer prevention, eliminating the need for additional surge suppressors or shock absorbers in most piping systems. Constructed with a rugged brass body and durable NBR seals, this 2-inch NPT valve provides a substantial 36 Cv flow capacity to ensure high-efficiency fluid handling. Operating on 120Vac, the unit includes a NEMA 4 enclosure, providing watertight protection for the solenoid. Whether used in large-scale laundry facilities, autoclaves, or cooling systems, the ASCO RedHat technology within this valve ensures reliable performance under operating pressures ranging from 5 to 150 PSI.

• Anti-Water Hammer Design: Integrated snubber slows closing speed to protect pipes and components from hydraulic shock.
• High Flow Efficiency: Large 2-inch port size with a 36 Cv rating supports demanding industrial flow requirements.
• Industrial Durability: Forged brass body and NBR elastomers provide excellent chemical compatibility with water.
• Weatherproof Reliability: NEMA 4 rated enclosure offers superior protection against water ingress and environmental debris.

• What is the minimum pressure required for operation? This pilot-operated valve requires a minimum differential pressure of 5 PSI to open.
• Can this valve be used for steam applications? The 8221G13 is specifically designed for water service; please verify compatibility for other media with our technical team.
• Does the slow-closing feature affect the opening speed? The snubber primarily controls the closing speed to prevent system shocks; opening remains responsive for standard cycle needs.
