Asco 221 Solenoid Valves – Features

• Pilot operated, normally open or normally closed
• Snubber slows disc closing speed to protect system against water hammer damage more effectively than other techniques
• Pressure spike due to water hammer is reduced to a point eliminating the need for suppressors or other controls in most water systems
• Fluid Controls Institute Inc. evaluations have classified these valves: Pipe Sizes Class 3/8″, 1/2″, 3/4″ 1″, 1 1/4″, 1 1/2″, 2″, 2 1/2″ FCI-82-1 CC BB

Typical applications of the ASCO 221 solenoid valves include in Medical ＆ Life Science, Oil ＆ Gas, Chemical and Water and Wastewater.

Hazardous Area LOCATIONS Certification

ASCO 221 valves are CSA certified – available with explosion-proof solenoid enclosure and also UL listed for fire protection systems. CSA certified solenoid valve.

ASCO SOLENOID VALVES – HAZARDOUS AREA LOCATIONS, safety & standards

ASCO solenoid valves (2-way, 3-way and 4-way type including NAMUR interfaces) control the critical flow of air, gas, water, oil and steam across all industries – hazardous area solenoid valves are available for Division and Zone classifications.

Class I, Division 2 and Zone 1/Zone 2 approved solenoid valves according to ATEX, IECEx, FM, CSA and UL are available. Flameproof and explosion-proof valves can be specified for potentially explosive atmospheres where there is a presence of flammable liquids, gases or vapours.

ASCO valves improve reliability and performance of safety systems according to IEC 61508, IEC 61511 and Safety Integrity Levels (SIL) – ASCO spool valves with SIL 4 capability are SAEL listed as assessed by Exida and TÜV.
