For Cast Carbon Steel | For Stainless Steel | Product Range | Special Specification |
The upper potion of the Yoke Sleeve is hexagonally tapered to fix the handwheel. The standard material is Nodular Ni-resist D2 with over 1150 degree dissolution point in accordance with API Std. spec. | |
The Body-bonnet bolts are manufactured in accordance with API Std. 600 spec. The nuts also strictly confirm with ANSI B1.1 The stud-bolt nuts, hexagonal, rigid and got-forged, bear material notation as well as do the bolt nuts made according to ANSI B18.2.2 | |
The bonnet and valve body have the same wall thickness. The body- bonnet flange drilling is spot-faced to exactly meet stud-bolt nuts. The bonnet back seat bushing guarantees packing replacement even when the valve is fully opened. The stem packing dimensions of the stuffing box are in accordance with API specifications. | |
The machined forged stem comes with a T-shape head, which connects the slot of the wedge. The Spherically shaped contacting surface of the head gives greater strength and durability. The stem dimensions are in accordance with API Std. 600 Specifications. The heat treated stem delivers adequate mechanical properties as well as excellent surface hardness. Further, opening/shutting friction is minimized by accurate machining and lapping. | |
Bottom seated type seat rings are welded or screwed into the body. They are forgings that have been heat treated to delived the best mechanical properties and required hardness. The difference in hardness between seats and wedge is in accordance with API specifications. | |
The standard disc of our valves is a one-piece flexible wedge. Slots are machined on both sides of the wedge to allow it to travel correctly in the integrally cast body guides. The wedge seating surfaces have been accurately machined, grind and lapped to a mirror finish to prevent leakage and eliminate galling. | |
The cast steel body is designed to insure a wall thickness which is greater at any point than the minimum specified by API Std. 600. Special care has been taken with the design of the Class 150 valve body so that the elliptically shaped center section is free from intensified stresses in the critical area. The body of above Class 300 are made circular in shape as much as possible to minimize distortion even under extreme operating conditions. Inlet and outlet port dimensions conform with ANSI B16.5 Pipe Fitting. The welded-in type seat ring is standard to insure interchangeabillity. Except for class 150, the standard body-bonnet joint is male and female. |
