Sanitary Diaphragm Valve
Diaphragm valves are so powerful in controlling fluid flow that they are widely used in a variety of industries, especially in applications that require a high level of sanitation and contamination control.
These valves are appreciated for their simplicity, reliability and ability to handle abrasive and corrosive media. There are two common types of diaphragm valves and they are are manual welded diaphragm valves and pneumatic welded diaphragm valves.
Next we will introduce these two types and learn more about sanitary diaphragm valves in terms of their features, benefits and typical applications.
Manual Welded Diaphragm Valve
A manual welded diaphragm valve is a basic, simple design that requires manual operation to regulate fluid flow.
It consists of a valve body, a diaphragm and a handwheel or lever for manual control.
The valve body connection is welded so it can be easily connected to the piping system.
The diaphragm, usually made of a flexible or thermoplastic material such as EPDM (ethylene propylene diene rubber) or silicone, is used as a sealing element to prevent direct contact between the process fluid and the valve body.
Advantages of Manual Welded Diaphragm Valve
- Simple design
Manual welded diaphragm valves are easy to operate and maintain, so choose them for applications that don't require automation.
- Cost-effective
Manual diaphragm valves are more cost-effective than pneumatic diaphragm valves in terms of cost and maintenance due to their simple design and lack of fear of failure.
Manual welded diaphragm valves are used in industries where precise flow control is not required but sanitation and contamination control are still critical.
Pneumatic Welded Diaphragm Valve
Pneumatic welded diaphragm valves are advanced valve bodies that incorporate automation for fluid flow control.
These valves are equipped with a pneumatic actuator, driven by compressed air or gas, to open and close the valve.
Advantages of Pneumatic Welded Diaphragm Valve
- Automatic Operation
If you need to make frequent adjustments or precisely regulate fluid, then choose pneumatic diaphragm valves because the pneumatic actuation of these valves allows for precise and automatic control of fluid flow.
- Remote Operation
Integration with automation systems enables remote monitoring and control, increasing operational efficiency and reducing the need for manual intervention.
Pneumatically operated welded diaphragm valves are ideally suited for automated process industries that require precise flow control and remote operation.
