Diaphragm shut-off and control valves Richter diaphragm valves are easy to use and reliable. They are reasonably priced and are therefore some of the most widely used shut-off, control and throttling valves. • PFA/PTFE lined diaphragm valves are used for corrosive, pure and ultrapure liquids, gases and vapours in chemical, pharmaceutical, food and industrial processes. • Hermetically tight • FDA-compliant, wetted PFA and PTFE materials • Soft-sealing, gas-tight • Operating pressures from -30 to +150 °C • Rated pressure: PN 16 (up to DN 50 or 2“), PN 10 (DN 80 or 3“ and larger); for...

© Diaphragm made of modified PTFE The quality and functionality of the diaphragm are crucial for the reliability and durability of the valve. Top priority is given to these aspects in Richter diaphragm valves. • Greater fatigue strength under reversed bending stresses and dimensional stability even after many switching cycles and at fluctuating temperatures • Higher density and lower permeability • All-round sealing bead limits the medium chamber exactly and thus prevents residues in sealing gaps which are difficult to flush • Thick-walled, more permeation-resistant than diaphragms made of...
