Directional control valves manage flow direction in high-pressure systems, opening pressure circuits or shutting them off. KAMAT manufactures directional control valves for operating pressures up to 4,000 bar and flow rates up to 240 l/min, designed for water and other fluids in demanding industrial environments.
Engineered for high pressure. KAMAT directional control valves are not derived from standard hydraulic components but developed specifically for operating pressures up to 4,000 bar. The seat valve principle with ball or cone element ensures permanently reliable sealing even under cyclic loading.
Designed for demanding fluids. Corrosive, abrasive, or water-based fluids place particular demands on materials and sealing systems. KAMAT selects materials on an application-specific basis and offers fluid-specific configurations for a wide range of process media.
Part of a modular high-pressure system. KAMAT directional control valves are part of a modular component system. Valves, pumps, and system components are coordinated with one another and can be combined into custom high-pressure solutions, simplifying engineering, maintenance, and spare parts management.
KAMAT Directional Control Valves — Technical Design for Extreme Pressures
Standard hydraulic valves are typically rated for pressures up to 350 to 500 bar. KAMAT high-pressure valves operate at pressures up to 4,000 bar and flow rates up to 240 l/min, a range that places fundamentally different demands on materials, sealing principles, and manufacturing precision.
The foundation is the seat valve principle with ball or cone element. It seals proportionally to pressure and remains permanently leak-free even under cyclic high-pressure loading — unlike spool valves, which are inherently more susceptible to leakage as pressure increases.
Material selection is guided by the process fluid. For water hydraulics and water-based fluids, KAMAT uses corrosion-resistant materials. Further fluid-specific configurations are available on request. All valves are manufactured in Germany. ATEX-compliant versions are available.
Directional control valves can be used as individual components or integrated directly into KAMJET Pump Skids and custom pump stations. KAMAT works with a modular component system: pumps, valves, and system components are coordinated and can be combined into custom high-pressure solutions without requiring special designs. The use of standardized components within the KAMAT modular system simplifies maintenance and spare parts supply and enables short response times for service and repairs.

Application areas for KAMAT directional control valves
KAMAT directional control valves manage high-pressure media across a wide range of industrial applications:
- Water jetting and high-pressure cleaning: Control of pressure circuits for cleaning ship structures, steel components, and concrete surfaces at pressures up to 4,000 bar.
- Concrete rehabilitation and demolition: Precise shutoff and redirection of the high-pressure jet for selective concrete removal.
- Waterjet cutting: Reliable switching of high-pressure water in automated cutting systems.
- Water hydraulics: Use in hydraulic presses, mining systems, and offshore installations where water serves as the hydraulic medium.
- Process technology: Control of process media in the oil and gas industry and the chemical industry, with fluid-specific material selection.
Advantages of KAMAT Directional Control Valves
KAMAT directional control valves are developed specifically for high-pressure systems that push standard hydraulic valves beyond their limits. Four characteristics make the difference in operation:
- Pressure rating up to 4,000 bar: Every valve is designed for the mechanical demands of extreme operating pressures. The seat valve principle ensures permanently sealed connections even under cyclic loading, reducing unplanned downtime and extending service life compared to conventional spool valves.
- Fluid-specific material selection: Whether water, water-based fluids, or other process media — KAMAT selects materials based on the corrosive and chemical properties of the respective fluid. Valve performance remains stable throughout the service life even with aggressive or abrasive media.
- Manufactured in Germany: Development and production take place at the Witten site. Short supply chains, high manufacturing quality, and long-term spare parts availability provide investment security for operators worldwide.
- System integration as standard: KAMAT directional control valves can be used as individual components or integrated directly into KAMJET units and turnkey pump stations. On request, KAMAT supplies fully integrated high-pressure systems including pumps, control technology, and safety-relevant components from a single source. Control concept, actuation type, and switching position are matched to the specific system, including ATEX-compliant configurations.
Which directional control valve is right for your operating pressure, fluid, and switching requirements is something we determine together in a technical consultation.
Frequently Asked Questions About Directional Control Valves
A directional control valve controls media flow through three basic functions: opening, blocking, and redirecting. The designation follows the pattern [ports]/[positions]: a 2/2 directional control valve has two ports and two positions and is suited to simply shutting off a pressure circuit. A 3/2 directional control valve switches between two positions with three ports, for example to activate a consumer while simultaneously opening the return line. KAMAT directional control valves are available in both configurations.
For valve design in high-pressure applications, a clear principle applies: spool valves, where a cylindrical piston opens or closes flow paths, are common in standard hydraulics up to around 350 bar. At pressures up to 4,000 bar, KAMAT uses seat valves with ball or cone elements. They seal proportionally to pressure, are low-leakage, and remain permanently sealed even under cyclic pressure loading.
Depending on the application and technical requirements, different actuation types are available:
- Electrically actuated directional control valves use solenoids to control flow. They are precise and fast, making them well suited to complex control tasks, particularly in industrial automation. Electric directional control valves offer high flexibility and can be used across a wide range of industrial applications.
- Pneumatically actuated directional control valves use compressed air to control flow. They are ideal for applications requiring fast, repeatable movements and are frequently found in automated systems and machinery where light forces and high speed are needed.
- Hydraulically actuated directional control valves offer highly reliable control in systems that rely on hydraulic fluids. They are designed for applications requiring high forces and precise control, as commonly found in mobile and stationary hydraulics. These valves are robust and suited to use in demanding environments.
For high-pressure applications up to 4,000 bar, pneumatically or electrically actuated seat valves are used depending on the control concept.
The first number indicates the ports, the second the switching positions. A 2/2 directional control valve opens or blocks a pressure circuit. A 3/2 directional control valve additionally switches between two flow paths, for example to activate a consumer while simultaneously opening the return line. KAMAT directional control valves are available in both configurations.
KAMAT directional control valves are rated for operating pressures up to 4,000 bar. Standard hydraulic valves typically operate up to 350 to 500 bar. Operation at extreme pressures is made possible by the seat valve principle with ball or cone element, which seals proportionally to pressure and remains leak-free even under cyclic loading.
KAMAT directional control valves are designed primarily for water and water-based fluids. Material selection is guided by the properties of the respective medium. Fluid-specific configurations are available for corrosive, abrasive, or chemically aggressive media. The right material configuration for your application can be determined on request.
In a spool valve, a cylindrical piston opens and closes the flow paths. This design is versatile and common in standard hydraulics up to around 350 bar. Seat valves seal via a ball or cone seat proportionally to pressure and remain leak-free even at very high pressures. KAMAT consistently uses the seat principle for all high-pressure applications.
In KAMJET Pump Skids and custom pump stations, directional control valves handle the control of individual pressure circuits, shutoff of consumers, and switching between different operating modes. Control concept and actuation type are matched to the specific system in each case.
