Cutaway Diaphragm Valves
There are two main types of diaphragm valves: one seals over a weir (saddle) and the other (sometimes called a "full bore or straight-way" valve) seals over a seat. The weir or saddle type is the most common in process applications and the seat-type is more commonly used in slurry applications to reduce blocking.
Diaphragm valves can be manual or automated. Their application is generally as shut-off valves in process systems within the industrial, food and beverage, pharmaceutical and biotech industries.
The CVA-DI series of cutaway weir diaphragm valves uses new industrial weir diaphragm valves that are cut away to clearly show the inlet, outlet, diaphragm, weir and actuator, allowing students to easily visualise valve operation and identify the main valve components.
