DVP6 Throttle-Globe Valve
3 week ago
Product details
I. Product Overview
TheDVP6 Throttle-Globe Valveis a hydraulic valve that combines throttling and shut-off functions, widely used in hydraulic systems to control fluid flow and pressure. By adjusting the valve port's flow area, it achieves precise flow regulation while providing a complete shut-off capability to block fluid flow entirely.

II. Key Specifications
1. Nominal Diameter & Flow Rate
• Nominal Diameter Options: Common sizes include DVP6, DVP8, DVP10, DVP12, DVP16, DVP20, etc., catering to varying flow demands.
• Flow Adjustment: The flow rate is regulated by rotating the adjustment knob to change the relative position of the plunger and throttle rod, enabling stepless flow control.
2. Pressure & Temperature Ratings
• Maximum Operating Pressure: Up to 35 MPa (some models may support higher pressures), suitable for high-pressure hydraulic systems.
• Temperature Range: Oil temperature: -20°C to +100°C; Viscosity range: 2.8–380 cSt (mm²/s), adaptable to diverse operating conditions.
3. Material & Construction
• Valve Body Material: Carbon steel, stainless steel, etc., ensuring corrosion resistance and durability.
• Sealing Structure: Features a self-locking adjustment knob and color-coded triangular opening indicator for reliable sealing and intuitive operation.

III. Product Features
1. Precise Flow Control
• Stepless flow adjustment is achieved by rotating the adjustment knob to fine-tune the flow passage area.
• A positioning screw fixes the set flow rate, preventing accidental changes during operation.
2. Reliable Shut-Off Function
• Rotating the adjustment knob counterclockwise to the极限 position (fully closed) ensures leak-free shut-off.
• Ideal for applications requiring complete fluid flow interruption.
3. Compact Design & Easy Installation
• Plate-mounted connection design simplifies integration into hydraulic systems.
• Lightweight construction (e.g., DV models: 0.12–10.90 kg; DVP models: 0.25–11.00 kg) saves installation space.
4. High Adaptability
• Compatible with mineral oils, phosphate esters, and other hydraulic fluids meeting DIN51524 and 51525 standards.
• Can be installed in the inlet, outlet, or bypass circuits to flexibly configure throttle speed control systems.

IV. Applications
1. Quantitative Pump Throttle Speed Control Systems
• Paired with relief valves to form inlet, outlet, or bypass throttle speed control systems for velocity regulation.
• Suitable for applications with minimal load variations or moderate speed stability requirements.
2. Hydraulic System Flow Control
• Used to regulate the motion speed of hydraulic cylinders, motors, and other actuators.
• Applied in equipment such as injection molding machines, die-casting machines, and forging presses.
3. Combined Use with Check Valves
• When paralleled with a check valve, it functions as a one-way throttle valve, enabling unidirectional throttling and free reverse flow.
• Ideal for pneumatic systems to prevent compressed air backflow.
------
V. Operation & Maintenance
1. Flow Adjustment
• Rotate the adjustment knob counterclockwise to reduce the flow passage area and decrease flow; clockwise rotation increases flow.
• After adjustment, tighten the positioning screw to prevent flow drift.
2. Shut-Off Operation
• Rotate the adjustment knob counterclockwise to the极限 position (fully closed) to block fluid flow.
• Ensure system pressure is released before shut-off to avoid high-pressure shocks.
3. Maintenance & Upkeep
• Regularly inspect valve sealing performance and replace aged seals.
• Clean the valve port to prevent clogging by debris, which may cause unstable flow.
• For long-term storage, set the valve port to the open position to prevent spring fatigue.
