ASCO 321 solenoid valves are part of the ASCO Red Hat range of valves.
ASCO 321 solenoid valves are part of the ASCO Red Hat range of valves.
ASCO 321 solenoid valves are pilot operated valves with resilient seated poppets for tight shutoff and are designed for quick venting to 0 psi through the exhaust orifice.
When using the ASCO 321 solenoid valves, the air is quickly exhausted to shift control valves.
Other key features of the valves include the ability to mount in any position and suitability of installations in many industries.
ASCO 321 Solenoid Valves – Ambient Temperatures
AC: 32˚F to 125˚F (0˚C to 52˚C)
DC: 32˚F to 104˚F (0˚C to 40˚C)
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.
