Features Advantages
Both connections can be loaded with maximum pressure Leakage-free tight
Taper-seat design (hardened, ground parts) Low operating force
Two sizes:
o NG5: Galvanised steel valve body (black chromated).
o NG8: Corrosion-resistant quenched and tempered steel. 		Installation: free or for panel mounting
Any mounting position Gentle, metered opening and closing
  High operational safety
  Star knob can be removed to prevent unintentional operation
  Insensitive to contamination in the hydraulic fluid , to high temperatures and to high pressure surges

Applications

  • Use instead of directional valves for "ad hoc" applications
  • Controlling movements of inspection and test equipment
  • For systems where pressure is to be built up or released in a targeted and metered manner
  • Applications where pressures have to be maintained over a long period of time.

Design

  • Taper-seat design (hardened, ground parts)
  • Any mounting position
  • Porting NG 5 and 8
