KAMAT high-pressure valves are designed for precise control, regulation, and protection of high-pressure systems in demanding industrial applications. Engineered for reliable operation under extreme pressures, they ensure stable process conditions and protect equipment and system components. Their robust design, wear-resistant materials, and high level of standardization enable long service life, high operational reliability, and low maintenance effort.
High-Performance High-Pressure Valves for High-Pressure Plunger Pumps
High-pressure valves are used for the safe operation of a high-pressure system. Pressure limiting valves, for example, ensure a constant operating pressure, directional control valves control lines, unloader valves and safety valves ensure greater safety. They can open and close lines even if they are under high pressure.
A constant operating pressure is relevant for many high-pressure applications. In order to guarantee this even in different operating states and with changing volume flows, a sophisticated interaction between the high-pressure pump and different valve types is necessary. Different valves are used depending on the application:
- Directional control valves distribute the flow volume of flow to the various consumers by switching individual lines on or off as required.
- Pressure limiting valves maintain the desired operating pressure by returning excess volume flow to the tank via a bypass line.
- Unloader valves relieve the pump when the consumer is closed and ensure that the pressure is maintained but the pump is hydraulically relieved in many water hydraulic systems.
- Safety valves limit the maximum permissible system pressure and protect the pump, pipes and system components from damage.
KAMAT designs and manufactures high-pressure valves, pumps, and core system components from a single source. This ensures that valve technology, high-pressure pump, and control system are optimally coordinated. For operators, this means greater process reliability, simplified commissioning, and a dependable spare parts supply throughout the entire service life of the system.
Special KAMAT high-pressure valves are rated for operating pressures up to 4,000 bar and are used worldwide in water jetting systems, water hydraulic systems, and demanding process applications.
A Wide Range of Controls for Individual Processes
With pneumatic, electric or hydraulic control of the high-pressure valves, the plunger pumps can be perfectly integrated into automated and remote-controlled processes. This integration offers enormous freedom in the control of processes. Our electrohydraulic solenoid valves can even be used up to an operating pressure of 3000 bar, which makes the above-mentioned integration into automated process control systems possible in many industrial applications.
Special valves for complex processes
Many high-pressure applications cannot be addressed with standard valves. KAMAT therefore develops custom valve solutions for demanding testing, control, and safety processes.
Examples include valve assemblies for pipeline pressure testing in the petrochemical industry and test rigs for qualifying carbon fiber reinforced pressure vessels in the automotive sector.
High-pressure valve materials
Material selection is application-specific, based on pressure level, medium, and operating environment. High-strength, corrosion-resistant materials are used alongside tailored sealing systems in PTFE, EPDM, NBR, FKM, or FFKM. This allows both water and aggressive or demanding process media to be handled safely.
Frequently Asked Questions About High-Pressure Valves
A high-pressure valve is a control element in high-pressure systems that opens and closes lines, limits or regulates operating pressure, and directs flow. Depending on their function, a distinction is made between directional control valves, pressure relief valves, unloading valves, and safety valves.
In industrial high-pressure systems, valves are central to safety, process stability, and system availability. They must operate reliably under extreme pressure loads and maintain a permanent seal over time.
KAMAT develops high-pressure valves for operating pressures up to 4,000 bar and integrates them directly into pump stations and custom high-pressure systems on request.
The most common valve types are directional control valves for managing pressure circuits, pressure relief valves for maintaining system pressure, unloading valves for system depressurization, and safety valves for protecting equipment and personnel.
In addition, special valves are used in specific applications such as pipeline pressure testing, water hydraulic systems, and automated test rigs.
KAMAT supplies high-pressure valves as individual components or as part of complete high-pressure solutions, allowing valves, pumps, and control technology to be optimally coordinated.
The maximum permissible operating pressure depends on valve type, materials, and application. KAMAT high-pressure valves are rated for operating pressures up to 4,000 bar.
For automated processes, electro-hydraulic solenoid valves with operating pressures up to 3,000 bar are available, allowing high-pressure applications to be integrated into modern control and automation concepts.
Our engineers will support you in selecting the right valve solution for your pressure, flow rate, and medium requirements.
KAMAT high-pressure valves are available with pneumatic, electric, or hydraulic actuation. This allows high-pressure pumps and process systems to be integrated into remote-controlled or fully automated setups.
