German Standard Spherical Flange Bottom Valve(dn350)

The German Standard Spherical Flange Bottom Valve(dn350) is actually a type of check valve that plays a role in preventing water backflow.

Bottom valves can be divided into plastic bottom valves and metal bottom valves according to material, as well as ordinary bottom valves and bottom valves with backwash water flow.

The bottom valve is mainly used in mechanical equipment such as water pumps for processing slurry. Usually, the bottom valve is installed at the bottom of the underwater suction pipe of the water pump to prevent slurry backflow

Product structure:

The bottom valve is equipped with multiple inlet ports on the valve cover and a screen to reduce the inflow of debris and reduce the probability of blockage of the bottom valve. Although bottom valves are equipped with anti clogging screens, they are generally suitable for cleaning media. Bottom valves are not suitable for media with high viscosity and particles.
