Features

• 1.Ultra-High Pressure Rating: Handles operating pressures from 0 to 400 bar (0—5，800 psi) depending on operator type for demanding hydraulic control applications

• 2.Metal-to-Metal Seated Design: 316 stainless steel seat ensures leak-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, 8 W option) 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 various grades of stainless steel/ceramic/aluminum bronze

• 5.Dual-Rated Explosion-Proof Certification: ATEX/IECEx II 2G EExd IIC 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.High Flow Capacity: Nominal flow rate of 200L/min（52.8US gal/min）for large hydraulic circuits requiring substantial fluid transfer

• 7.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

• 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: IP66/NEMA 4X standard for superior water and dust protection in harsh outdoor installations

• 10.Easy Maintenance: Dismountable via 4 bolts without disturbing pipework, reducing 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
