The electro-pneumatic valve 4/2 ATEX 94/9/EC directive ‘ATEX’ is a variant of 4/2 electropneumatic valve designed to operate in potentially hazardous environments, for areas classified as Zone 1 and 21 due to the presence of Group-IIC flammable gases and combustible powders.
The 4/2 electropneumatic valve is fully protected against the external environment and can operate without difficulty even in the most severe environmental conditions.
Its function entails alternatively establishing a connection with pump’s supply and one of the two delivery lines, thereby simultaneously allowing a release in pressure in the other to occur.In a resting state, the valve closes both of the lines.
Indicated in particular for dual-line systems with SUMO-line DropsA pumps.
