Bolted cover construction.
Piston design is fully guided thereby ensuring there is
no chatter on seat face during closure.
Integral satellite seats eliminate galling and withstand
on-line erosion and corrosion thereby
increasing valve
life.
Body/cover gasket is fully encapsulated thereby
eliminating chances of direct line pressure acting on
the same. This increases gasket life and eliminates chances of body/cover
leakage.
Testing as per API 598 using kerosene.
End preparation socket weld as per ANSI B 16.11. |
