4 inch Swing Check Valve, DN100, CPVC

Buy a 4 inch swing check valve from ATO.com. It is a CPVC check valve that can transport weak acid and weak alkali medium. 100mm non-return valve is commonly used in pipelines where reliable backflow prevention is required, such as water supply, wastewater treatment, irrigation and industrial processes.

Features

• The check valve can prevent the phenomenon of liquid counter-current from protecting the pump equipment.
• Because it is a cantilever check valve, there is less resistance to flow.
• The 4 inch swing check valve uses CPVC materials and plays a strong corrosion resistance to prevent acid and alkali fluid.
• Not only can the valve body be removed from the pipeline, but also the valve cover can be opened for internal inspection and maintenance.

Tips: Swing Check Valve vs. Ball Check Valve

Both swing check valves and ball check valves are types of check valves used to prevent the backflow of fluids in a piping system. However, they have different designs and operate differently.

A swing check valve has a disc that swings on a hinge or pivot to allow flow in one direction and prevent flow in the opposite direction. When fluid flows in the correct direction, the pressure pushes the disc out of the way, allowing the fluid to pass through. When the fluid flow stops or reverses, the disc swings back into place, preventing backflow. Swing check valves are often used in applications with low to moderate flow rates.

A ball check valve, on the other hand, has a spherical ball inside the valve that moves up and down in response to fluid flow. When fluid flows in the correct direction, the pressure lifts the ball, allowing the fluid to pass through. When the fluid flow stops or reverses, the ball falls back into place, preventing backflow. Ball check valves are often used in applications with high flow rates.

Overall, both swing check valves and ball check valves are effective at preventing backflow, but the choice of valve depends on the specific requirements of the application, including flow rate, pressure, and fluid type.
