The DCV10 Tilting Check Valve is a high-performance, non-return solution specifically engineered to prevent damaging backflow and water hammer in critical large-diameter pipelines. Designed to meet the stringent demands of modern infrastructure, this valve delivers exceptional operational reliability, long-term durability, and efficiency in municipal pump station and industrial applications.
At the heart of the DCV10 Tilting Check Valve is its hydraulically efficient disc, which is hinged above its center of gravity. This design ensures that the disc opens fully at low flow velocities and closes quickly upon flow reversal, minimizing slam and reducing pressure surges (water hammer) within the system. This advanced mechanism guarantees energy efficiency by ensuring low head loss during normal forward flow conditions.
Manufactured from high-strength, corrosion-resistant materials and built with a robust ductile iron body, the DCV10 Tilting Check Valve is designed to withstand continuous high flow rates and challenging fluid environments. Its flanged design allows for secure installation into horizontal or vertical pipelines. The streamlined passage and quick-closing action significantly reduce noise and vibration, contributing to lower maintenance costs and minimizing the potential for unplanned downtime.
The DCV10 Tilting Check Valve is ideally suited for applications in raw water pumping, clean water distribution lines, power generation cooling water systems, and wastewater discharge manifolds where swift and reliable backflow prevention is essential. Its superior closing dynamics and reliable performance make it a preferred choice for engineers seeking a high-integrity, standards-compliant solution for long-term protection against dynamic pipeline forces.
In summary, the DCV10 Tilting Check Valve offers an optimal combination of hydraulic efficiency, long service life, and robust protection against backflow. With its low head loss design, durable construction, and fast-closing tilted disc mechanism, this unit stands as a trusted solution for modern fluid control and pipeline protection requirements worldwide.
1. General Information
The DCV10 Tilting Check Valve is designed for use in distribution networks and pumping stations, requiring reliable backflow prevention. Proper installation is essential to guarantee safe operation, long service life, and efficient, leak-free performance.
2. Safety Precautions
Installation must be performed by qualified personnel only.
Ensure strict compliance with all local safety regulations and standards concerning pipeline pressure and heavy equipment handling.
Wear appropriate personal protective equipment (PPE).
Confirm that the pipeline section is fully depressurized and drained before attempting to install the DCV10 Tilting Check Valve.
3. Pre-Installation Checklist
Installation must be performed by qualified personnel only.
Ensure strict compliance with all local safety regulations and standards concerning pipeline pressure and heavy equipment handling.
Wear appropriate personal protective equipment (PPE).
Confirm that the pipeline section is fully depressurized and drained before attempting to install the DCV10 Tilting Check Valve.
4. Installation Procedure
Positioning: Install the DCV10 Tilting Check Valve ensuring the flow direction matches the arrow cast on the valve body. The valve must be installed with the hinge pin axis horizontal in a horizontal pipeline.
Use the appropriate gaskets suitable for the medium and operating conditions.
Align the valve precisely with the pipeline flanges and insert bolts, tightening them gradually and crosswise in incremental steps. This ensures even compression of the gasket and prevents stress on the valve body.
5. Post-Installation
Positioning: Install the DCV10 Tilting Check Valve ensuring the flow direction matches the arrow cast on the valve body. The valve must be installed with the hinge pin axis horizontal in a horizontal pipeline.
Use the appropriate gaskets suitable for the medium and operating conditions.
Align the valve precisely with the pipeline flanges and insert bolts, tightening them gradually and crosswise in incremental steps. This ensures even compression of the gasket and prevents stress on the valve body.
Proper maintenance extends the service life of the DCV10 Tilting Check Valve and ensures reliable backflow prevention. Follow the guidelines below to maximize the longevity of this essential unit.
1. Routine Operation
Visually inspect the DCV10 Tilting Check Valve exterior weekly during initial commissioning to ensure the disc operates smoothly and closes completely after pump shutdown. Avoid operating the connected pump below its rated minimum flow, as this can cause disc flutter and unnecessary wear.
2. Inspection Schedule
Monthly, check the valve exterior for external leaks around the body, inspection cover, and flange connections.
Quarterly, listen for any signs of disc chatter or excessive noise during operation, indicating potential seating issues or low flow.
Annually, perform a detailed internal inspection by removing the inspection cover to check the hinge pins, disc alignment, and seat condition.
3. Lubrication
The hinge pins and internal mechanism of the DCV10 Tilting Check Valve are generally designed to be maintenance-free or lubricated for life. Consult the manufacturer’s technical manual for specific lubrication requirements, if any, for the hinge pins or external mechanisms.
4. Seal and Gasket Replacement
Replace the inspection cover gasket and any external O-rings immediately if external leakage is observed during operation. The seat or disc seal should only be replaced if internal leakage (backflow) is detected after a pump shut-off test. Always depressurize and drain the pipeline thoroughly before attempting any internal maintenance work.
5. Cleaning
Replace the inspection cover gasket and any external O-rings immediately if external leakage is observed during operation. The seat or disc seal should only be replaced if internal leakage (backflow) is detected after a pump shut-off test. Always depressurize and drain the pipeline thoroughly before attempting any internal maintenance work.
6. Storage and Spare Parts
Store spare parts (gaskets, seals) in a dry, clean, and cool environment, away from direct sunlight and harsh chemicals. Maintain a detailed record of all inspections, internal part replacements, and repairs performed on the DCV10 Tilting Check Valve unit.

Frequently Asked Questions about the DCV10?
What are the main advantages of this valve?
The DCV10 Tilting Check Valve offers significant advantages in preventing severe water hammer due to its short disc travel and fast closing action. It also provides low head loss, which results in better pump efficiency and reduced energy consumption over its service life.
Why should I choose this product?
This valve delivers outstanding performance in both sealing and durability, making it a dependable choice for demanding applications. Its straightforward design facilitates easy installation, offering flexibility during system design. With a wide range of material options, it meets the needs of various infrastructure projects, from municipal water networks to industrial facilities.
What is the primary function of the DCV10 Tilting Check Valve?
The primary function is to permit flow in one direction (forward flow) and automatically prevent flow reversal (backflow) without requiring external power or manual intervention, ensuring the protection of pumps and other upstream equipment.
Can the DCV10 Tilting Check Valve be installed in a vertical line?
Yes. The DCV10 Tilting Check Valve can be installed in vertical lines with upward flow. However, special attention must be paid to ensure the hinge pin remains aligned correctly to guarantee the fast, gravity-assisted closure necessary to mitigate water hammer.
How does the DCV10 Tilting Check Valve minimize water hammer?
Water hammer is minimized because the disc is engineered to tilt and close rapidly with the aid of gravity and flow dynamics, reaching the seat just before or at the moment of flow reversal, thus avoiding the high impact forces typical of slow-closing check valves.
