Flange valves

Vickers by Danfoss flange valves are mounted directly on pump flanges to minimize the potential for leakage. In addition to reducing installation costs and space requirements, the cartridge design of these valves ensures stable performance and fast opening and closing. Our unloading, check, and relief valves are suitable for pressures up to 350 bar [5,000 psi] and flows up to 750 l/min.

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 

Applications 

  • Die casting and foundry
  • Machine tooling
  • Marine and offshore
  • Presses
  • Plastics
  • Pulp and paper
  • Turbine control (wind, steam, water)
  • Wood processing

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.
