ASCO 202 Solenoid Valves – Preciflow Proportional Medical & Analytical Valve
ASCO 202 solenoid valves and preciflow proportional valves designed for the control of air and inert gases by varying electrical input signal to the coil.
With low hysteresis, excellent repeatability and high sensitivity, the ASCO 202 solenoid valves are ideal for high precision flow control.
ASCO 202 Solenoid Vales – Product Features
The compact friction-less architecture saves valuable space in analytical and medical instrumentation. In addition the valves do not require a minimum operating pressure and are well suited to vacuum operation.
Other key features include power consumption as low as 1W to meet the most stringent instrument power requirements.
ASCO 202 solenoid valves also meet all relevant CE directives, and are RoHS compliant.
ASCO 202 Solenoid Valves – Typical APPLICATIONS
Typical applications include:
- Gas Chromatography
- Mass Flow Controllers
- Dental Equipment
- Blood Pressure Monitoring

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.
