■ BOLTING

The body-cover bolting conforms with ANSI B.1,1 The nuts are manufactured to confirm with ANSI B18.2.2

■ 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. 600 or API 6D. Port and seat passage dimensions conform to ANSI B16.5 Pipe Fitting the welded-in type seat ring is standard to allow interchangeability. the standard body-bonnet joint is male-female, and the flange is round for all valves.
