221 Series Brass, 2-Way, NO, Slow Closing Solenoid Valve
Manufacturer: Asco LP
Mfg Product Code:
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
- A specially designed snubber offers slower disc closing speed to protect systems against water hammer damage.
- Pressure spike due to water hammer is reduced to a point eliminating the need for suppressors or other controls in most water systems
- Hot water service to 150 psi (10 Bar) differential @ 210°F (100°C)
- Pilot-operated, normally open, or normally closed models are available with a full range of pipe sizes up to 2 1/2.
- Broad range of standard AC and DC voltages available
