ASCO 221 Slow-Closing Water Solenoid Valve
The ASCO Series 221, also known as 8221, with its unique slow-closing design, provides higher flow while increasing throughput in commercial applications. It reduces inventory by accommodating both hot and cold-water service, and is designed for quick, easy maintenance. Apply the 221 Series with confidence in high and low-temperature applications found in laundries, molding, sterilizers and autoclaves.
Features
1.A specially designed snubber offers slower disc closing speed to protect systems against water hammer damage.
2.Pressure spike due to water hammer is reduced to a point eliminating the need for suppressors or other controls in most water systems
3.Hot water service to 150 psi (10 Bar) differential @ 210°F (100°C)
4.Pilot-operated, normally open, or normally closed models are available with a full range of pipe sizes up to 2 1/2.
5.Broad range of standard AC and DC voltages available
