Product Information
Gate Valves
Bodyand Bonnet
The bodv is constructed with uniform sections and generous radius fillets to prevent stress on all sides. The body has a straight through port without recess except between the seats to achieve minimum turbulence, erosion and resistance to flow. The bolted bonnet is Silted with a back seat ring to guide the stem and provide a back seat when the valve is fully open. The yoke is cast in tegrated with the bonnet. The body-bonnet joint for ASME Class 150 valves is oval in shape and plain faced. In ASME Class 300 and 600 valves, the bonnet joint is circular in shape and male-female type. Any kinds of gasket materials can be supplied according to customer's requirement
Wedge
One piece flexible wedge ensures tight seating over a wide range of differential pressures and temperatures. Stress concentrations are minimized due to one piece flexible wedge of which the cross section of the wedge is a tapered H in shape. In addition, the flexible wedge adjusts the movement of body seat.
Seat Ring
Seal welded seat rings are designed to achieve minimum pressure drop and prevent damage by corrosion. Leakage through the path between the seat rings and the body is also eliminated.
Stem
The sten has the 'T' head engaging with the T-slot in the wedge. Its surface is precisely machined and ground to reduce friction to extend stem packing life and ensure perfect tightness. The stem also has a back seat shoulder to match with the back seat ring in the bonnet.
Yoke
The yoke, when not integral with the bonnet, is exactly machined to match the bonnet and insure perfect with the backseat bushing and stem
YokeSleeve
The yoke sleeve Has the long thread to ensure accurate alignment of the stem. The yoke sleeve is mounted on thrust bearings to facilitate easy operation for 14" or over in ASME class 150~300, and 6" or over in ASME class 600
Gland
The gland is self-aligned and comprises a gland flange in cylindrical shape. A shoulder prevents it from pressing the gland packing and getting pushed into the stuffing box.
Stuning Box
The stuffing box is designed to extend the life of packing rings.Class 300 and above valves are equipped with a lantern ring between the packing rings.
End Connections
The standard flange ends have a raised face serrated finish type which conforms to ASME B16.5 RF. ASME class 600 valves ave supplied with RTJ end flanges on request.
Operation
All valves are offered with hand wheel, gear operator, or actuators(electric, hydraulic, or pneumatic) according to customer's requirements.
