The new DN5 Series hydraulic solenoid valve from Midland-ACS is designed specifically for severe offshore environments. Manufactured from 316 stainless steel, the DN5 Series is suitable for actuator and wellhead control, the valves delivering leak-tight shut-off and the ability to switch safely and reliably at high pressures. The DN5 is a 3-port, 2-position series of hydraulic control valves. It incorporates a stainless steel metal-to-metal seat design that ensures leak-tight shut off, even at operating pressures of up to 690bar. Offering nominal flow rates up to 20l/mn, and suitable for use on a wide range of fluids including mineral oil, synthetic and water glycol-type fluids, the DN5 is ATEX certified and also holds BASEEFA and UL/CSA approvals. The valves feature an “O” ring interface that enables them to be fitted with a 3/8” NPT ported subplate as standard. The DN5 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.
