ASCO 458 Solenoid Valves – Rocker Isolation Valve (In-Line Barb Porting)
ASCO 458 solenoid valves are suitable for corrosive applications and media that would attack valves designed for general service duty.
The patented ASCO 458 rocker isolation solenoid valves feature a unique rocker diaphragm mechanism that shields the internal components of the solenoid from the fluid.
This unique design forms an easy to flow, low volume internal cavity.
ASCO 458 Solenoid Valves – Product Features
- Suitable for corrosive media that can attack valves designed for general service duty.
- Prevents contamination of fluid sample, due to excellent flushing characteristics.
- Rocker design significantly reduces erratic flow caused by pumping action in poppet style valves.
- Standard built-in manual operator for testing or troubleshooting.

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.
