1 1/2 inch Swing Check Valve, DN40, CPVC

The provided 1.5 inch (1 1/2") swing check valve is designed to prevent backflow and ensure unidirectional flow in piping systems. It is a 40 mm one way check valve, CPVC material for super chemical resistance and heat resistance and long service life.

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 1.5 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. Lift Check Valve

Swing check valves and lift check valves are two types of check valves used in piping systems to prevent backflow, but they operate using different mechanisms.

A swing check valve has a hinged flap that swings open to allow flow in one direction and swings closed to prevent backflow. When the flow stops, gravity causes the flap to swing closed, thereby preventing backflow. Swing check valves are typically used in applications where the flow rate is low to moderate and the backflow pressure is relatively low.

In contrast, a lift check valve has a disc that moves up and down to allow flow in one direction and prevent backflow. When the pressure on the upstream side of the valve is greater than the pressure on the downstream side, the disc lifts and allows flow. When the flow stops or reverses, the disc drops back into place, thereby preventing backflow. Lift check valves are typically used in applications where the flow rate is higher and the backflow pressure is greater than what a swing check valve can handle.

The main difference between a swing check valve and a lift check valve is the direction in which the disc moves to allow flow and prevent backflow. In a swing check valve, the disc swings open and closed, while in a lift check valve, the disc moves up and down. The choice between the two types of valves depends on the specific application and the flow and pressure requirements.
