Main design features and advantages
- Gate valve ZМ80х70 and ZMG80х70 or ZM80x35 and ZMG80x35 which serve as shutoff devices have die-forged body parts that ensures their high strength reliability. Gate has "metal-to- metal" seal.
- Manifold is assembled from several units.
- The system includes both hand-operated gate valves and hydraulic powered ones. The last can be also opened manually in emergency cases.
- Seats of angle chokes and check valve as well as needle and gate of check valve are hardfaced.
- Industrial oils I12А, I20А and I30А at ambient temperature more than -10oC or hydraulic oils ВМГЗ and М8Ги at ambient temperatures -10oC to -40oC can be used as control liquid for this hydraulic powered actuator.
- The pressure of control liquid in the hydraulic powered actuator equals 1,500 psi.
