The DGR 06 F2 52 valve is produced by Vickers within the Pressure Control Valves series and regulates hydraulic line pressure in automated machinery. It is pressure operated, so the internal mechanism reacts directly to system pressure without external pilot flow. An interface size of 06, equal to 3/4-inch ports, matches common manifold patterns and simplifies circuit design. The body length of 10.310 in houses the spring cartridge and damping passages, and the 3.820-in body width provides a broad sealing surface for leak-free installation. A body height of 3.500 in keeps the unit low enough to avoid interference with adjacent equipment. Subplate or manifold mounting enables rapid replacement during maintenance, and design number 52 links the valve to the correct spare-part kits.
The valve withstands a maximum operating pressure of 3000 psi, giving headroom for transient spikes, while the adjustable setting can be tuned up to 2000 psi to establish the desired relief level. A flow capacity of 60 gpm accommodates medium-size pumps without inducing excessive pressure loss. Reliable service is maintained between –20 °C and 70 °C, covering cold starts and elevated ambient conditions. Compatibility with petroleum oils keeps seals stable and prevents swelling in common hydraulic fluids. A cleanliness level of 19/17/14 limits particulate contamination that could erode the seat or restrict spool movement. Together these limits allow the valve to protect actuators and piping from overload while maintaining consistent system performance.
