From the catalogue's introduction to this valve type: GATE VALVES Low operation torque design. Self aligning two piece packing gland. High quality packing for reliable tightness and low emission performance. Outside Screw and Yoke (OS&Y). Standard construction of body-bonnet connections are bolted bonnet or welded bonnet type. Back-seat design. Standard gasket design for bolted-bonnet valves is spiral wound type up to class ASME 1500. Ring Joint gaskets are standard for ASME 2500 and above. SPW/RJ are available on request for all pressure classes as option. Fully guided wedge for wear reduction of seating surfaces. GATE VALVE DESCRIPTION Gate valves are primarily designed for on-off services when a straight-line flow of fluid and minimum restriction is desired. The closure member of gate valves either stops or allows flow through the valve and acts somewhat like the opening or closing of a gate and is called, appropriately, the gate valve. The gate is also shown as a wedge, due to the shape is resembles. When the valve is open, the closure member is fully drawn up into the valve, leaving a complete opening for the flow stream. Therefore, there is little pressure drop or flow restriction through the valve. Gate valves are used in many industrial applications including the oil and gas industry, pharmaceuticals, manufacturing, automotive, and marine. Gate valves are not suitable for throttling purposes. Full die forged structure for all pressure containing parts. Flanged valves are provided with flanges integral with the body forgings. Best-in-Class CV values. Low wedge-seat friction coefficient for reliable sealing & long service life.
