Tilting Disc Check Valve Application

　　Because the disc of a tilting disc check valve is mounted tilted at an angle of 15⁰, this valve opens at speeds as low as 0.6 m/sec and the response time is minimal. This prevents ''stalling'' of the disc at low speeds and prevents wear on the spindle, springs and bearings. The self-centering seal provides excellent sealing at both high and low pressure differentials. In addition, the valves can be expanded with additional springs to increase the response speed if the probability of fast-return flow is high.

Advantage Of Tilting Disc Check Valve

　　★Prevents Backflow: The primary function of a check valve is to prevent the backflow of fluids in a piping system. It ensures that the flow of fluid occurs in one direction only, effectively blocking reverse flow. This is especially important in situations where backflow could cause damage, contamination, or interference with the intended flow direction.

　　★Protects Equipment and Systems: Check valves help safeguard equipment and systems by preventing potential damage caused by reverse flow. They act as a barrier, preventing fluids from flowing back and causing issues such as pump damage, pipe collapse, water hammer, or contamination of sensitive components.

　　★Maintains Pressure: Check valves assist in maintaining optimal pressure levels within a system. By allowing fluid to flow in the desired direction and preventing backflow, they help maintain the desired pressure conditions, ensuring efficient operation of pumps, regulators, and other pressure-sensitive equipment.

　　★Enhances System Efficiency: Check valves contribute to the overall efficiency of a system. By preventing reverse flow, they eliminate the need for additional pumps or mechanisms to counteract backflow, thereby reducing energy consumption and operational costs.

　　★Minimizes Water Hammer: Water hammer, characterized by sudden pressure surges or shockwaves in a system, can lead to pipe damage and system failure. Check valves help mitigate water hammer by preventing reverse flow and the subsequent pressure spikes that can occur.

　　★Allows for System Isolation and Maintenance: Check valves provide a means of isolating sections of a system for maintenance or repairs. By closing off the valve, the flow of fluids can be stopped in a specific direction, allowing for safe and efficient maintenance procedures.
