EATON Danfoss RV3-16 Series Pressure Control Valves


Eaton Danfoss RV3-16 Series pressure control valves are designed to control the pressure in various applications like machine tools, hydraulic presses, plastic injection moulding machines and other industrial machinery. They feature a spring-loaded poppet that moves in response to changes in th...e system pressure. They also include Buna-N seals & screw-in cartridge installation for a leak-free connection. They also incorporate a screw-type adjustment, allowing for easy and precise adjustment of the pressure set point. Read more

Working Mechanism

  • These valves feature a flat or conical disc, known as a poppet, that controls fluid flow through the port.
  • It is held in place by a spring which moves off its seat when pressure is applied, allowing fluid to flow. This reduces the pressure in the system until it reaches the set point.
  • When the pressure is released, the spring returns the poppet to its seat and stops the flow. This increases the pressure in the system until it reaches the set point again.

Frequently Asked Questions

What is the difference between cartridge and SAE-type ports?

  • Cartridge ports are self-contained, replaceable components inserted into a manifold or valve body. These units are smaller and are typically used in mobile hydraulic systems where space is limited and a high degree of flexibility is needed.
  • SAE ports, on the other hand, are rigid and used in high-pressure applications. These units are larger in size and are designed to be threaded or welded into a manifold or valve body for a secure connection.

What is the advantage of using Buna-N seals?

Buna-N (nitrile) seals are used in pressure control valves to provide excellent resistance to oils, fuels and hydraulic fluids. They are also resistant to abrasion and wear and can withstand temperatures up to 120 degrees Celsius. They are installed in the poppet assembly where they provide a tight seal between the valve components to prevent leaks and ensure smooth operation.

What is the purpose of screw-in cartridge installation?

This installation method is used to install hydraulic valve cartridges into a manifold block or valve body. The process involves threading the cartridge into a threaded bore in the valve body (using a wrench) to ensure that it is tightened to the correct specifications. This method provides a secure, leak-free connection between the valve cartridge and manifold block.
