Some is Hard alloy stellite covered, some is 13 Cr seat. Swing check valve, in size 4″ ,6″,12″ 20″ in class 150lb, 300lb, 600lb, 900lb by carbon steel , alloy steel for water, and steam application. Together with these valves, counter flanges and bolts nuts gaskets all also supplied for some item. These valves and flanges, pipe assessarys are mainly used in Refinery of Mexico Pemex. Some of the valves might be stock for standby. These valve are manufacturered and designed by API standard, API600, API598 for inspection. The clients representive come to factory and inspected some item by random. The first lot  passed site inspection and some were shipped and on the way to oveaseas.By this SGV establish stragety relationship with Lati american valve market.

Flow direction of globe valve, down-to-up or up-to-down, Stem diameter?

Generally speaking, the flow of globe vales is from down to up. It means the medium will go through from disc downside then out by upside. Globe valves usually adopt compulsory sealed design, so close valve by offer pressure to disc against seat. So if you want to open valve, the globe valve disc must overcome resistance made by stem and packing friction, medium pressure will offer adverse pressure which help open valve. It means you can use less force than closing valve. So the stem diameter should be larger, to avoid stem bending fault.(depends on metal material physical performance of stem ). In recent years, there are more and more valve pressure seal, the medium through upper disc to down disc, so the close valve force is smaller than the open valve force, valve shaft diameter are allowed to be smaller.

About Gate Valve

The gate valve, also known as a sluice valve, is a valve that opens by lifting a round or rectangular gate/wedge out of the path of the fluid. The distinct feature of a gate valve is the sealing surfaces between the gate and seats are planar, so gate valves are often used when a straight-line flow of fluid and minimum restric­tion is desired. The gate faces can form a wedge shape or they can be parallel. Gate valves are primarily used to permit or prevent the flow of liquids, but typical gate valves shouldn’t be used for regulating flow, unless they are specifically designed for that purpose. Because of their ability to cut through liquids, gate valves are often used in the petroleum industry. Continue reading “About Gate Valve”
