A Weir type diaphragm valve is a simple device that is used in many processing and manufacturing industries. The Weir type diaphragm valve gets its name from the weir orifice plate that is used to create the differential pressure across the membrane.
With KDV’s multiple options for lined valves, the weir types are benefiting from a resurgence in popularity as more and more engineers and end users have been reminded of the benefits of the diaphragm valve capabilities. Our recent stock takes highlights these valves are not being kept too long on stocks as we receive a volume of quotes for it.
These valves can be used for a wide range of applications such as:
- General purpose on/off, control and even relief functions
- Corrosive, abrasive or inert liquids and gases
- High purity liquids and gases
- Slurries or particle-laden fluids
The advantage of the weir diaphragm valve is that it can be used with a wide range of fluids, including those that are corrosive or abrasive. The valve is also able to handle pressures and temperatures others valve types cannot compete with on certain process media, the diaphragm valve can be made from a variety of materials, offer a wide range of lining options and diaphragm grades depending on the application on hand.
