CG10F20

The CG10F20 valve belongs to the Pressure Control Valves series manufactured by Vickers and serves as a relief valve that limits hydraulic system pressure to a preset level in automation circuits. It is manually operated, allowing an operator to adjust system pressure without electrical controls. The unit is built in Size 10 format so it fits standard cavities common to mid-frame manifolds. Subplate or manifold mounting simplifies integration into compact hydraulic blocks and keeps service points accessible. A 3000 psi pressure rating defines the upper limit the valve will pass to tank, preventing over-pressurization of actuators and piping. The design supports flow rates up to 120 gpm, making it suitable for high-volume pump outputs. These characteristics enable precise pressure capping while accommodating the flow and space requirements of industrial machinery.

Cast iron construction gives the CG10F20 the strength needed to handle repeated pressure cycles and resists deformation under thermal load. A nitrile seal set maintains internal leakage control and offers compatibility with common petroleum-based fluids. The valve requires fluid cleanliness of 19/17/14 per ISO 4406 to avoid spool wear and ensure stable cracking pressure over long service intervals. Operation is permitted down to –20 °C (–4 °F), allowing cold-start performance in unheated equipment bays, while an 80 °C (176 °F) maximum temperature limit protects elastomers from heat-induced degradation. A single SAE 20 port with 1-5/8-12 UN threads matches large-bore hoses used on main pressure lines and simplifies assembly with standard fittings. Together these specifications define environmental limits and connection details so the valve can be reliably applied in diverse hydraulic installations.
