Series VVXA31/32For Air, Gas, Vacuum and Oil

Compatible with a wide varietyof fluids.Application can be matched by simply choosing the correct seal material (NBR, FPM or EPR).

It is possible to replace valvewithout changing existing piping.Configuration can be changedfrom N.C. to N.O., and from N.O.to N.C. easily.Weight-saving aluminium baseand body.(Not applicable to water or steam.)
