Example of Application
In the simplest variant, a single-acting consumer (Example 1) is protected. For this purpose, the valve is installed in the pressure line to the consumer and connected to the tank. It is also possible to limit the maximum pressure for a specific attachment tool (example 2) - when the valve is switched, the pressure is limited. This is useful if the factory setting of the machine is not to be changed. Housings for two valves are available for double-acting consumers such as shears, crushers and other tools
Applications
- Pressure protection of various consumers
- Single-acting consumers such as hammer
- Double acting consumers, e.g. shears, pulverizer
