Which valves are used in water treatment equipment

In water treatment equipment, the following valves are commonly used:

Stop valve (check valve): used to control the switch of fluid to prevent fluid backflow or reflux.

Regulating valve (regulating stop valve): used to adjust the flow, pressure or temperature of the fluid. The valve opening can be adjusted as needed to adjust the flow or pressure.

Butterfly valve: a disc-shaped valve disc rotates around the valve axis to achieve switch control, suitable for large flow control and regulation.

Ball valve: a spherical valve disc rotates to achieve switch control, and the fluid flows through the orifice of the sphere, which is suitable for fast switching and cutting off the fluid.

Safety valve: used to control the safety limit of pressure in the system. When the pressure exceeds the set value, the valve will automatically open to release the over-pressure fluid.

Exhaust valve: used to remove air from the system to prevent gas accumulation from affecting the normal operation of the system.

Pneumatic control valve: switch and regulation control is achieved through pneumatic actuators (such as pneumatic pistons, pneumatic diaphragms, etc.), and is often used in automation systems.

Overflow valve: used to control the fluid pressure in the system. When the pressure exceeds the set value, the valve will open and guide the excess fluid out of the system.

Electric valve: It realizes switching and adjustment control through electric actuators (such as electric motors), and is often used in automation and remote control systems.

The above are some valves commonly used in water treatment equipment. Depending on the specific process and needs, other types of valves may also be used.
