Valvola ad angolo - BAV 35" ANSI

Valvola Angolare ISO-K ISO-F

The DN250 to DN1000 and ANSI 10 to 35 are right-angle valves with an electropneumatic drive. The double-acting piston transfers the pneumatic through the piston rod to the valve disc. The pneumatic drive of the piston is controlled by a 5/2 way pilot valve.

Features and Benefits

• The bellow sealed valves operate free of hydrocarbons as the piston rod is sealed off completely against the atmosphere by bellow in the direction of the vacuum process. A groove provided at the pneumatic drive equalizes the pressure in the bellow. It also acts as a sniffer bore for helium leak testing. The valve may be easily disassembled by removing the bonnet plate from the body which will provide easy access to the bellow and the poppet.
