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. For extremely thick fluids, a specialty valve often known as a knife valve is used to cut through the liquid. On opening the gate valve, the flow path is enlarged in a highly nonlinear manner with respect to percent of opening. This means that flow rate does not change evenly with stem travel. Also, a partially open gate disk tends to vibrate from the fluid flow. Most of the flow change occurs near shutoff with a relatively high fluid velocity causing disk and seat wear and eventual leakage if used to regulate flow. Typical gate valves are designed to be fully opened or closed. When fully open, the typical gate valve has no obstruction in the flow path, resulting in very low friction loss.Specifications:      Product Name Cast Steel DIN Standard Flanged ends Gate Valve1.

Technical Specification: 1.Design and Manufacture: DIN33522.Inspection and Test: ISO 5208、EN122663.Flanged ends dimension: EN 1092-1、DIN2544 PN25、DIN2545 PN40、DIN2546 PN644.Butt-welded ends dimension: EN126275.Face to face and end to end: DIN3202、EN558-1、ISO57526.Pressure-temperature ratings: DIN2401Technical Descriptions: Construction  The construction of steel gate valves of MSA corresponds to API 600 and BS 1414. Gate valves are yoke, flanged or welded with unnarrow flow rate and with flexible or fixed wedge. Bodies, covers and yokes are cast. Wedges could be forged or cast. All wedges are guided. Sealing seats are bolted or welded into the body. Overlays in seats depends on Trim. Valves have rising non-rotative spindle and bolted joint of body-cover. Standard spindle threads are ACME2G-LH.  Operation with a handwheel. On the basis of mutual agreement, the gate valves can be operated by angle transmission, electric actuator or pneumatic actuator. For easier control the gate valve with larger diameters are equipped with bearings. Sealing material is pressed rings from expanded graphite and graphited plaited rings. The properties of gate valve packing meet the requirements of the directive Clean Air Act, Amendment from 1990. The gate valves can be also equipped with: drainage, venting, relief from interspace and bypasses, on the special customer´s request.  Design Dimension  The dimensions of standard design are stated in the table below.  Material design  The gate valves are supplied in different material variants.  Assembly  The yoke gate valve can be assembled in any position into the pipeline.  Testing  The gate valves are subjected to pressure tests according to the standard API 598: on strength and tightness, tightness of backseat, closure tightness by low pressure, closure tightness by high pressure (on request).  Competitive Advantage: ●We are manufacturer, not a trading company, we can control every production process to guarantee the quality of our products.●18 Months warranty after delivery.●Offer free samples for testing before orders.●We have convenient shipping sea port, and standard exporting carton boxes & plywood cases.●100% leakage testing.●100% inspection & testing for every production process before delivery.●Light torque for easy operation & long service life.    Part Name GP240 GH Stainless Steel Stainless Steel Body1.06191.43081.4408Bonnet1.06191.43081.4408Wedge
