Flange Valves

Where to buy

Reduced leakage points and space requirements

Vickers by Danfoss flange valves are directly mounted to pump flanges, reducing potential leakage points. We offer unloading, check, and relief valves with pressures up to 350 bar [5,000 psi] and flows up to 750 l/min. Delivering reduced installation costs and space requirements, these valves offer fast opening and closing action combined with stable performance from the cartridge design

Features and benefits

  • Excellent repeatability and stable performance from cartridge design main stage parts  
  • Easy installation and servicing of components  
  • Pilot design minimizes response time and cracking flow, which allows for high pressure stability  
  • Superior leak resistance due to reduced potential leak points 
  • Fast opening and closing action and stable performance from cartridge design 
  • Minimum unloaded pressure drop due to short piping runs  
  • Multi-fluid capability without the need to change seals 

Specifications and technical data

Relief valves improve machine reliability and uptime by limiting the pressure in a hydraulic circuit to the desired maximum, thereby protecting the hydraulic pump and system from pressure peaks. The CPF relief valves are designed to mount on a wide range of SAE pump outlet port flanges to eliminate intervalve piping and fittings.  

Unloading valves are used in accumulator charging circuits where a pressure regulator is required to automatically unload the pump. The UPF unloading valves are designed to mount directly on SAE pump outlet port flanges to eliminate intervalve piping and fittings.  

Check Valves are designed for superior shock resistance, reliability and long life. The check valves may be mounted directly on an SAE pump outlet port flange or may be stacked with a CPF relief valve to provide a pump unloading function.

Don’t forget the subplates and bolts kits

To install industrial valves, you need subplates and bolt kits. This hardware is engineered especially for Vickers by Danfoss valves and manifolds to give your systems the flat surfaces and stiffness required for a reliable seal.
