Pressure Limiting Valves

Pressure limiting valves are special hydraulic components that are used to limit the pressure in a system to a specified maximum. They prevent the pressure in a line or tank from exceeding a critical value, which can lead to damage to components or hazards. The valves ensure that excess volume flow is discharged to guarantee the safety and functionality of the overall system.

The pressure limiting valve essentially consists of a piston or diaphragm that closes a by-pass by an external force. When the pressure in the system reaches the preset maximum value, the high pressure presses against the piston or diaphragm, opening the valve and allowing the excess flow to escape. As soon as the pressure falls below the set value again, the valve closes automatically.

Features of KAMAT pressure limiting valves:

• Pressure setting: the valves can be set to a specific maximum pressure, which can be adjusted at any time. This allows the valve to be adapted to the specific requirements of a system.
• Safety function: They serve as protective devices to prevent overpressure and the associated damage or danger to machines, systems and people.
• Versatile areas of application: Pressure limiting valves are used in various applications, especially in hydraulic systems such as KAMAT’s high-pressure pumps.

Pressure limiting valves from KAMAT play a decisive role in high-pressure systems by reliably limiting the pressure and thus ensuring the safety of systems and machines. Our pressure limiting valves are specially developed for use in plunger pumps. They reliably ensure the optimum working pressure and enable precise limitation – both mechanically and pneumatically controlled.

• Versatility: Our valves are made from special materials and are ideal for demanding media such as those found in the process industry.
• Robustness: Thanks to ceramic or Stellite control rods, our valves are particularly resistant and durable.
• Remote control: A pneumatic remote control enables flexible limitation of the pressure.
• Customization: We offer the option of supplying the valves according to the requirements of your application, including the choice of materials.

Rely on KAMAT when it comes to precise pressure limitation. Our pressure limiting valves are the ideal choice for high-pressure applications.
