Diaphragm valves
Diaphragm valves
The answer to problems of: corrosion, abrasion, clogging, contamination, vacuum & gas handling
G&O Diaphragm valves do not incorporate any stuffing box and are leaktight on all liquids, slurries, granular materials, powders, pastes, gases, acids, etc…
Diaphragm (internal membrane) is supported during opening and closing, and is easily replaceable without any special tools. The wide range of available elastomer materials enable an appropriate selection for each application and is a guarantee of perfect resistance to corrosion and abrasion.
Sanitary type valves are recommended for ultimate sterility in pharmaceutical and biotechnology industries. Using perfectly contoured self-draining stainless steel bodies and PTFE faced diaphragms, resulting in valves totally free of bacteria traps.
PERFORMANCE FEATURES
• Long diaphragm life: no metallic inserts to strain the elastomers• Low pressure loss• Diaphragm supported during opening and closing: hence the possibility of under vacuum operation• Quick and easy replacement of diaphragm• Epoxy painted, valve bodies protected with an anti-acid varnish
