Seal-less bypass valves
05 July 2013
Wanner International has introduced a range of heavy duty, seal-less diaphragm bypass valves that are reported to provide accurate, repeatable smooth response without causing "chatter" in bypass lines.
The Hydra-Cell C62/C63/C64 Series offers accurate, repeatable, smooth operation with minimal pressure surge and "chatter-free" bypass. Available in a choice of 316 stainless steel, Hastelloy or brass body with PTFE or Viton 'O' rings and PTFE diaphragm, the valves are suitable for use in systems pumping corrosive or dirty liquids. They can be used with any positivedisplacement pump with flows up to 151lpm.
The Hydra-Cell Valve design is simple: a tapered plunger with an attached diaphragm. When excess pressure overcomes the adjustable spring pressure onthe plunger, the plunger lifts off the valve seat, allowing fluid to bypass and reduce system pressure.
