Engineering, Manufacturing and Supply of Hydraulic Valves: Types KOF and KPF

Check and pressure relief valves with a nominal bore of 63 mm (DN 63 mm), flanged mounting execution.

Commissioned by an industrial enterprise, we engineered and manufactured specialized hydraulic valves:

  • Check Valves (Type KOF)
  • Pressure Relief Valves (Type KPF)

The valves feature a nominal bore of DN 63 mm and flanged connection ports. Equipped with solenoid-actuated pilot control, the valves provide circuit pressure unloading upon energizing or de-energizing the pilot directional valve solenoid. These units are 100% mechanically and dimensionally interchangeable with legacy units while offering enhanced operational reliability and field maintainability.

Design & Operational Highlights

These valves are deployed within the hydraulic systems of critical industrial facilities. The project achieved full import substitution, guaranteed uninterrupted system operation, and earned positive performance reviews from the client.
