1 Direct Operated Port Valve Series A1/2 For Gas Vacuum Water and Oil Variations Proper selection of body and sealing materials permits application of a wide variety of fluids. Application can be matched by simply choosing body material (Brass or Stainless steel) and seal material(nbr FPM or EPR). C.O. style easy to use; operatable as either N.C. or N.O. Easy to disassemble and reassemble in a short time. Compatible with high viscosity fluids (500cSt). Common (C.O.)
