The main features of these valves are :
- through conduit type
- no retention area
- enabling pigging of the line
- metal-to-metal seating or lamellar seats
- seating surfaces protected from process medium during opening/closing strokes
Main optional arrangements
- hard faced seating surfaces for a better resistance
- removable bottom for body cleaning
- additional connections for draining or steam sweeping
- spring loaded seats
Operation
- handwheel or manual gear
- pneumatic, electric or hydraulic actuator
Materials These valves can be manufactured in a wide choice of stainless steels and special alloys available for fabricated (welded) construction.
