Characteristics:

BODY AND BONNET:

The gate valve body has a straight through port without recesses except at the seat area. This ensures minimum turbulence, erosion and resistance to flow. Bonnet castings are of one-piec design, where the yoke is integral with the bonnet for gate valves of sizes up to 12 inch.

STEM

Non-piece construction Stem, ACME threaded and precision-machined with polished sur-faces to reduce friction, minimize leakage and exntend stem life.

SEAT RING:

A seal-welded seat ring that offers a leakproof design as it sliminates the leakage path between the seat ring and body. Threaded seat rings are optional.

FLEXIBLE WEDGE:

Oneipiece cast flexible wedge that minimizes stress concentration.Wedge flexibility ensures tight seating over a wide range of differential pressures and temperatures.It also adusts to slight misalignments caused by pipeline deflections and thermal deformation.
