Parker’s robust and durable pilot operated directional control valves series D31DW, D31NW, D*1VW are almost universally applicable and ensure a reliable operation. A wide variety of spools and options allows to design an unlimited number of hydraulic circuits.
The pilot operated directional control valves are available in 4 sizes: D31DW (standard) and D31NW (high flow) in NG10/NFPA D05, D41VW in NG16/NFPA D07, D81VW (for port diameter up to 26 mm) and D91VW (for port diameter up to 32 mm) in NG25/NFPA D08 and D111VW in NG32/NFPA D10.
All sizes are optionally available with position control.
Markets:
• Industrial
Benefits:
• Proven robust design that represents our long-term experience in hydraulics
• Wide range of spools – suitable for almost all hydraulic circuits
• High functional limits – low forces resulting in safe operation also at high flow rates
• Low pressure drop – resulting in low energy losses in operation
• Short delivery time – no warehousing necessary
• Optionally with position control
• Optionally without manual override
• Optionally as explosion-proof version
Applications:
• Suitable for general hydraulic applications
Note:
The minimum pilot pressure must be ensured for all operating conditions of the directional valve. Additionally spools with a P to T connection in the deenergized position need an external pressure supply (external inlet) or an integral check valve.
