Solenoid valves for hazardous and corrosive areas

The new 67 Series of direct-acting solenoid valves has been developed for use in corrosive and hazardous environments in the petrochemical, process, chemical, oil and gas and food industries

The new 67 Series of direct-acting solenoid valves from Midland-ACS has been developed for use in corrosive and hazardous environments in the petrochemical, process, chemical, oil and gas and food industries.

ATEX approved, the marine grade (316L) stainless steel valves are particularly suited to general-purpose piloting, diverting or mixing tasks with gases, air and light oils.

Available in three pipe sizes of 1/4'', 3/8'' and 0.5'' NPT, and rated for operation up to 20 bar (with 10 bar max differential), the 67 Series solenoid valves are highly rugged in their construction and offer high degrees of ingress protection: IP65 on standard enclosures and IP67 on explosion-proof, ATEX certified enclosures.

To ensure reliability in the most corrosive environments, the 67 Series valves employ internal parts of 316 stainless steel and seals of Nitrile (standard) or optional Viton and EPDM materials.

These combinations enable the valves to be used on gases, air and light oils across the widest ambient temperature range, from - 50C to +70C.

The 67 Series are 3/2 configuration valves offering the flexibility for normally open (NO), normally closed (NC), and Universal operation.

They are supplied with 100% continuously-rated Class H solenoids, in 24v DC and 24v, 110v, 120v and 230vAC configurations (50/60Hz).

The solenoids have the option of being equipped with manual- overrides or manual resets, and users also benefit from a choice of connection options, including PG9 (via a DIN plug), on the standard enclosure, and a 20mm facility on the explosion proof housing.

Complementing these are 0.5'' and 0.75'' NPT options.

The 67 Series valves can be supplied either as discrete units or as part of fully designed, assembled and tested systems in stainless steel, or marine grade flameproof enclosures.

In these systems Midland-ACS combines the 67 Series with other pneumatic and hydraulic control valves in its range, and also ancillary components, to provide bespoke control panels for use on oil and gas rigs offshore.
