HD – DZ….DP – Direct Operated Sequence Valve
Enhance your hydraulic system's efficiency and guarantee perfect mechanical timing with the HD DZ…DP Series Direct Operated Sequence Valve. Available through Thm Hydraulics, this highly responsive valve provides reliable, instantaneous control for sequential operations in compact and mid-sized circuits. Designed to trigger a secondary hydraulic function only when the primary circuit reaches a specific, pre-set pressure, the direct-operated mechanism eliminates electronic lag. Built to accommodate sizes 5, 6, and 10, the DZ…DP series comfortably manages operating pressures up to 315 bar and flow rates up to 80 L/min, ensuring your automated machinery operates with absolute, fail-safe precision.
Core Technical Specifications:-
- Component Architecture: Direct Operated Pressure Sequence Valve
- Model Sizes: HD-DZ5, HD-DZ6, and HD-DZ10DP (Sizes 5, 6, and 10)
- Maximum Operating Pressure: Up to 315 bar
- Maximum Flow Capacity: Up to 80 L/min
- Pressure Ranges: 25, 75, 150, 210, and 315 bar configurations
- Pressure Adjustment: 3 or 4 distinct optional adjustment elements
- Mounting Style: Sub-plate mounting
Key Features & Engineering Advantages:-
- Instant Direct-Acting Response: Unlike pilot-operated valves, the direct-acting internal spool reacts instantly to pressure thresholds, making it the perfect choice for fast-paced, highly sensitive sequential operations.
- Flawless Mechanical Sequencing: Ensures that secondary actuators (like a drill or press) cannot physically engage until the primary actuator (like a holding clamp) has reached full operating pressure.
- Optional Integrated Check Valve: Can be configured with an internal check valve to allow free, unrestricted reverse flow. This ensures your cylinders can retract quickly and efficiently without requiring complex external bypass plumbing.
- Highly Granular Pressure Tuning: With five highly sensitive pressure ranges available (starting as low as 25 bar), engineers can perfectly calibrate the exact moment the secondary circuit is triggered.
- Custom Adjustment Security: Choose from 3 or 4 different adjustment elements to lock in your pressure settings, protecting the valve's calibration from heavy machine vibrations or unauthorized tampering.
- Leak-Free Subplate Integration: Engineered for standardized sub-plate mounting, providing a clean, space-saving, and leak-proof installation on your manifold blocks.
Ideal Industry Applications:-
The rapid response time and 80 L/min flow capacity make the HD DZ…DP Series the premier choice for:
- Precision Machine Tooling: Guaranteeing workpieces are securely clamped at full pressure before high-speed CNC cutting, milling, or drilling operations commence.
- Automated Assembly Lines: Synchronizing the precise timing of compact robotic actuators, indexing tables, and fixture circuits to prevent product damage.
- Small-Scale Hydraulic Presses: Ensuring proper sequential staging for multi-cylinder metal forming and component pressing equipment.
- Injection Molding Auxiliaries: Managing the precise timing of core pull functions and ejector pins during fast-paced manufacturing cycles.
Why Choose the HD DZ…DP Series?
- Eliminate Machine Collisions: Foolproof your machinery. This valve ensures your secondary actuators never fire before the primary ones are securely locked, preventing catastrophic tool breakage.
- Lightning-Fast Reaction: For smaller circuits under 80 L/min, direct operation provides the fastest possible sequencing, speeding up your overall machine cycle times.
- Compact & Modular: Designed to cover sizes 5, 6, and 10, it integrates flawlessly into modern, space-saving manifold blocks without adding unnecessary bulk.
