Gate valves are primarily used for stop valves fully opened or fully closed. They are not normally considered for throttling purposes, but more for slurries, viscous fluids, etc. Gate valves are characterized by a traveling wedge, which is moved with the operation of the stem nut. The wedge travels perpendicular to the direction of the 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. BODY & BONNET The design of the body and bonnet is calculated to achieve the most regular distribution of stress in all directions, as well as the minimum turbulence and resistance to flow. Valve bonnets are equipped with a backseat bushing. The yoke is integrally cast on Pressure Classes 150 and 300 up to 12” and up to 10” on Class 600 and higher ratings. BODY-BONNET JOINTStandard body-bonnet joints of gate valves are machinedas follows:PRESSURE CLASS JOINT DESIGN150 Flat Faced300, 600 Male-and-Female900* & over Ring Type Joint*Pressure Class 600 also available in Ring Type Joint.EMFLO can supply any style of gasket required by customer. GATE All gates are fully guided to the seats. As standard our valves are supplied with a solid flexible gate that has a tapered H cross-section. The flexible wedge is cast or machined with a circumferential groove to allow the seating surfaces to move independently and adjust to movement of the body seats. This design is beneficial where line loads or thermal expansion of the system is likely to distort the seat face in the valve. This design of gate is ideally suited for steam or other high temperature services and is especially useful to prevent sticking where valves are closed when hot and opened when cold. SEAT RING Seat rings are designed to greatly reduce and/or prevent any turbulence and avoid damages due to the corrosion. The seat rings are forged or rolled in one piece, and then seal welded and overlaid, if required. After welding and all required heat treating, the seat ring faces are machined, thoroughly cleaned and inspected before leaving for assembly. STEM The stem connection to the gate is a T-head design which is integral (without welding) with the stem. The accuracy in the dimensions and finishes assure a long life with a perfect tightness in the packing area, resulting in lower fugitive emissions. The stem-to-gate connection is designed to prevent the turning or the disengagement of stem from the wedge while the valve is in service. Through calculations and extreme testing, the strength of the stem-to-gate connection has proven to exceed the strength of the stem at the root of its operating thread. STEM PACKING The stem packing is designed and arranged to ensure a maximum seal along the stem during operation or while at position, thus allowing for a greater reduction in fugitive emissions. Our packings are NON-ASBESTOS types. EMFLO can supply any style of packing required by our customer. STUFFING BOX The depth of the stuffing box allows for a sufficient amount of packing, which makes the stem seal. Our standard packing arrangement and stuffing box design meets

We are Manufacturer, Exporter and Supplier of superior quality Globe Valves. Our Globe Valves are manufactured by using high quality raw materials. Our Globe Valves have been precisely designed by our manufacturing experts. Our Globe Valves are used in various industries. Globe Valves supplied by us are praised by our esteemed clients for their robust structure and high durability. Applications Used as control valves where throttling or both throttling and shut-off are requiredCan also be used for on-off service; however, because of the design, a pressure drop becomes inherentConfined to on-off applications where valve is normally closed and pressure drop is not important when the valve is openUsed with the flow and pressure under the disc Construction : Are commonly made in outside screw and yoke designs with full ports (including seat ring) and heavy-duty, conical plug type discs Minimum Order Quantity : 2 Units Range Size Range : 1 1/2" - 20"Class : Class 150 / Class 300 / Class 600 / Class 1500 Types : End Connection - Flanged / Lug / Wafer Operation : Hand Wheel , Gear Operator, Electrical Actuator Download
