plug cocks are manufactured from Aisi 304L and Aisi 316L stainless
steel and are made with sections complete with couplings, press-forged
or hot-rolled and solution heat-treated.
Plugs are coated in a galvanic bath with very hard
and thick chrome deposit. There is a high degree of taper in the
couplings to reduce specific rotation pressure of plugs.
The standard finish is 120 grit (Ra 1.01-1.14 µm
The maximum operating pressure is 4 bars.
