High Pressure Valves for precise pressure control in clamping systems

In high-pressure hydraulics, valves perform the central task of pressure regulation and directional control. In clamping processes, the absolute tightness of the valves is crucial to maintain a constant clamping pressure throughout the entire machining time. ABNOX high-pressure valves are designed for operating pressures of up to 700 bar and ensure safe handling of the medium – without pressure drop and with minimal wear.

The requirements for valves in clamping hydraulics are extreme: they must withstand high switching frequencies while simultaneously guaranteeing a hermetic seal. ABNOX relies on proven poppet valve technology and hardened materials that are resistant to pressure peaks and abrasive particles in the hydraulic oil.
 

Our Valve Categories at a Glance:

• Inlet Valves
  These valves provide controlled delivery of the hydraulic medium into the clamping circuit. They are designed to securely shut off the flow once the target pressure is reached and prevent the medium from flowing back. The precision mechanics allow for sensitive dosing during pressure build-up.
• Release Valves:
  Upon completion of the machining process, relief valves must reduce the system pressure safely and in a controlled manner. Our designs are optimized for high flow rates without cavitation and allow for rapid release of the clamping fixture, which optimizes cycle times in production.

• Advanced Sealing Technology: 
  Use of specialized high-pressure seals and precision-ground valve seats for maximum leak-free performance.
• Robust Housing Design: 
  Compact dimensions made of high-strength steel, ideal for direct mounting on clamping blocks or within tight fixture spaces.
• Ergonomic Operation: 
  Manually operated valves feature optimized haptics to enable precise switching even under high back-pressure.
• Low Maintenance: 
  Due to the high surface quality of the internal functional parts, mechanical wear is reduced to a minimum, increasing the service life of the entire system.

The use of ABNOX high-pressure valves prevents the unintentional loosening of clamping fixtures, protecting both machine safety and component quality. Through the exact separation of pressure build-up and pressure reduction, complex clamping sequences can be realized. With our components, you rely on a control level that is technologically synchronized with the high demands of modern machining.
