ASCO 212 solenoid valves. T&D are an ASCO Numatics Authorised Distribution Channel.

ASCO 212 solenoid valves are part of the ASCO Red Hat range of valves.

ASCO 212 solenoid valves are composite valves used for the purification, distribution and conditioning of water in industrial markets with membrane based reverse osmosis systems.

Reverse osmosis systems are typically found in several drinking water applications including restaurants, food and beverage equipment, and grocery store vegetable misting.

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 – hazardousSIL IEC 61508 - Solenoid Valves 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.
