Body

:

Thebodyis robust and designed with smooth lines to allow a better stress distribution. This allows an obstruction- free flow with minimum turbulence. The seat ring housing is machined for a very smooth finish, which guarantees a metal seal in body- ring area. The Threading depth depends on the depth required to secure the ring in place.

Cover

:

The Cover is designed to be used under the same pressure and temperature as the body of the valve. In rating 150 and 300 the upper flange has a machined section to place the gasket . For the rating 600 and above RTJ joint to tongue and groove.

Disc

:

The Disc is normally manufactured from the same material used for the body, but welded with the same trim material , on the seat surface., The hinge’s mounting bolt is part of the clapper to guarantee a hermetic seal.

Seat Ring

:

They have a thick wall as well as a long threaded section to secure the ring to the body of the valve. Once set in the place, it is grinded to guarantee a total seal with the clapper and eliminate the possibility of any deformation. Manufactured from the same material specified for the Trim or the same Trim material in the sealing area.

Hinge

:

The hinge is normally manufactured from the same material as the body. Designed to resist the violent slams of the clapper generated when the fluid flows back.

Hinge Pin

:

Generally made of stainless steel or the same material used for Trim . Its primary function is to maintain the clapper-hinge set in the correct position function is to maintain the clapper-hinge set in the correct position inside the valve, allowing free rotation.
