APPLICATIONS
Industrial Machinery - Cover plates can be used for periodic flushing of the hydraulic system. They can also be used to connect ports internally without the need of an extra directional valve.
Construction Equipment – The Lynch Cover Plate can be used to block off a bar manifold station of a feature that is no longer required.
COVER PLATES
Cover plates are used in place of directional valves to completely block off a bar manifold station or to provide a means for flushing a manifold as determined by the internal port connections chosen. They are available in Parallel and series models.
FEATURES AND BENEFITS
  • Optional Gauge Port available on Pressure Port.
  • Internal passages maximized to match the interface port connection in order to minimize pressure drops and fluid velocities.
  • Special D05D valve pattern matches both D05H and D05HE
  • Cover plates with all external ports for relocating valves are available.
  • Special combinations of ports including X & Y ports are non-standard.
  • Servo Cover Plates are available.
