Rotork Midland-ACS DN5 Series Solenoid Operated Valves

The Rotork Midland-ACS DN5 Series is a range of 316L stainless steel metal-to-metal seated hydraulic solenoid pilot valves engineered for ultra-high-pressure flow control in safety-critical industrial applications. Designed specifically for actuator and wellhead control systems in oil, gas, and petrochemical industries, this 3-port, 2-position (3/2 way) series delivers leak-tight shut-off and reliable switching performance at pressures up to 690 bar (10,000 psi). With its balanced internal piloting system, the DN5 Series enables low-powered solenoid coils to switch safely at extreme pressures, making it ideal for remote installations with limited power supply.

Features

  • 1.Ultra-High Pressure Rating: Handles operating pressures from 0 to 690 bar (10,000 psi)depending on operator type, making it suitable for demanding hydraulic control applications

  • 2.Metal-to-Metal Seated Design: 316 stainless steel seat and ball construction ensures btubble-tight shut-off even at max pressure, reducing fluid loss and reducing system efficiency

  • 3.Balanced Internal Piloting: Allows low-powered solenoid coils (3.5 W standard) to switch reliably at extreme pressures, reducing energy consumption in remote installations

  • 4.316L Stainless Steel Construction: Exceptional corrosion resistance for harsh chemical, marine, and offshore environments, with wetted parts in stainless steel for extended service life

  • 5.Dual-Rated Explosion-Proof Certification: ATEX/IECEx II G Exd T6 (-50°C ≤ Ta ≤ +60°C) and T4 (-50°C ≤ Ta ≤ +80°C) as standard for Zones 1 & 2, Gas Groups IIA, IIB, IIC

  • 6.Modular Mounting Options: O-ring interface enables subplate or manifold mounting for use in local control panels, providing a compact, cost-effective solution for multi-well panels

  • 7.High Flow Capacity: Nominal flow rate of 20L/min(5.3 US gal/min)with the ability to scale up when combined with DN3 valves for larger hydraulic circuits

  • 8.Wide Temperature Range: Standard -20°C to +60°C, with low-temperature option available (-50°C to +60°C) for extreme cold environments

  • 9.Ingress Protection: IP67/NEMA 6 standard for superior water and dust protection in harsh outdoor installations

  • 10.Easy Maintenance: Dismountable via 4 bolts without disturbing pipework, minimizing downtime and contamination risks during service

  • 11.Filtration Requirement: 10 micron absolute recommended for optimal performance and longevity at extreme pressures

  • 12.NACE MR-0175 Compliant: Suitable for sour service applications in the oil and gas industry
