Valve Advantages: Along with the advantages of the spring-loaded diaphragm valves, tied-diaphragm valves incorporate features which provide additional benefits. A major benefit of the tied-diaphragm design is that it has a much lower internal volume, less surface area, and less complex surfaces in the gas path than other designs. These attributes make the tied diaphragm valve more appropriate and successful for corrosive gas service. In all services, the tied-diaphragm valve is the most easily purged, particle-free valve design now in use. Anti-extrusion stem tips and anti-inversion diaphragm configurations are incorporated in this design, eliminating those potential problems.
