GLT GATE VALVE Application & Function Gate valves are primarily used for stop valves fully opened or fully closed and are not normally considered for throttling purposes, but more for slurries, viscous fluids, etc. Gate valves are characterized by a traveling wedge that travels perpendicular to the direction of flow. Gate valves usually have a minimum pressure drop when fully open, provide tight shut-off when fully closed, and remain relatively free of contamination buildup. Construction: Cast steel gate valve, outside screw and yoke, bolted bonnet, rising stem, non-rising hand wheel, flexible solid wedge, designed according to API 600. General Information: General Design : API 6D Face to Face : ANSI B16.10 Flange Type : ANSI B16.5 Rating : Class 150, 300, 600 & 900 Sizes : 2 " through 24 " Standard Materials: Body / Bonnet : ASTM A216-WCB Stem : ASTM A182-F6A Wedge : ASTM A216-WCB+ 13Cr Seat Ring : ASTM A105 + 13Cr Packing : Graphite GLT Valves produces a wide variety of types, classes and materials of check valves.

GLT GLOBE VALVE Application & Function Globe Valves are primarily used as control valves where moderate control or regulation of flow is required. Globe valves are marked with flow direction arrows as they are recommended to be installed with flow and pressure under the disc. The amount of force to close a globe valve against pressure is much higher than gate valves but the distance the stem travels is much less. Construction: Cast steel globe valve, outside screw and yoke, bolted bonnet, rissing stem, rissing hand wheel, swivel plug disc, designed according to API-600. General Information: General Design : API 600 or BS1873 Face to Face : ANSI B16.10 Flange Type : ANSI B16.5 Rating : Class 150, 300, 600 & 900 Sizes : 2 " through 20 " Standard Materials: Body / Bonnet : A216-WCB Stem : A182-F6A Disc : A216-WCB + 13Cr Seat Ring : A105 + 13Cr Packing : Graphite GLT Valves produces a wide variety of types, classes and materials of check valves.

GLT CHECK VALVES GLT Check Valves are available in 2 types : Swing Check Valves and Wafer Check Valves available in a range of sizes and pressures. Check Valves are single-direction flow valves used to allow unlimited flow in one direction and to restrain flow in the opposite direction. Check Valves are normally designed for installation in horizontal lines but may also be used in vertical lines where the flow is upward under the disc. GLT Swing Check Valves Application & Function Swing check valves are straight through flow valves which work automaticallly. The disc swings from the seat upon exertion of fluid pressure on the upstream side. When the direction flow reserves, the reversal pressure and the weight of the disc close the disc against the seat, stopping backflow. This design allows the valves to remain closed even with no flow going through the valves.
