Bolting
The body-cover bolting conforms with ANSI B.1.1
The nuts are manufactured conform with ANSI B*8.2.2
Cover
The cover material is identical to the body.
Depending on the valve size and pressure class, either a casting or
a forging is used.
Hinge Pin
The hinge pin is inserted into the valve and held in position by
plug.
The larger size valves are provided with bolted flanges instead of
plugs.
Arm
The arm material is identical to the body.
Hinge bushing is provided in the larger valve sizes to minimize
friction and eliminate seizing.
Seat Ring
The bottom seated type seat ring is screwed into the body.
The seating surface is finished by lapping.
The forged seat ring is heat-treated to deliver the best mechanical
properties and required hardness.
Disc
The disc has a sufficient seating surface area which is ground
and lapped to a mirror finish.
It is of one-piece construction and is heat treated to deliver the
required mechanical properties and hardness.
Body
The cast steel body is designed with a wall thickness which is
greater at any point than the minimum requirement provided by API
Std.**0 or API 6D. Port and seat passage dimensions conform to ANSI
B*6.5 Pipe Fitting. The welded-in type seat ring is standard to
allow interchangeability.
The standard body-bonnet joint is male-fernale, and the flange is
round for all valves.
