Tips: Are diaphragm valves manual?

Diaphragm valves can be operated manually or automatically, depending on the specific application and the design of the valve.

Manual Operation: In many cases, diaphragm valves are designed to be operated manually. This involves turning a handwheel or lever to control the position of the diaphragm, which in turn regulates the flow of the fluid through the valve. Manual diaphragm valves are often used in situations where precise control of flow is not critical, and they are relatively simple to operate.

Automatic Operation: Diaphragm valves can also be automated using various mechanisms such as pneumatic or electric actuators. Automated diaphragm valves are commonly used in industrial processes where precise and remote control of fluid flow is required. These valves can be controlled by computers or other control systems, and they can be integrated into larger automated systems.
