Description
The control relief valve is a pressure relief valve that provides overpressure protection for hydraulic systems and components. When system pressure reaches a predetermined level, the spool is forced off its seat, allowing excess fluid to flow through the valve and out of the system.
Features
- Designed for the operating conditions of the fluid.
- Designed to withstand extremely high pressures and temperatures.
Applications
The control relief valve diverts excess fluid out of the system to prevent system damage.
