1500 LB Pressure Seal Gate Valve is mainly used in the pipeline of the fire station in a variety of systems, cut off or connected piping media. Applicable medium: water, steam and other non corrosive media. Compared to the power station valves and other valve products is characterized by high temperature and high pressure, the unique self seal design, the higher the pressure, sealing more reliable. Due to the special properties of technical characteristics, conditions of formation of the products can not be replaced by other product characteristics. Compared to the power station valves and other valve products is characterized by high temperature and high pressure, if only from the pressure than the common valve low, simple from the temperature than was lower than the common valve. Due to the special properties of technical characteristics, conditions of formation of the products can not be replaced by other product characteristics.

Forged Steel Bellows Gate Valve are mainly used on the pipelines of various systems of thermal power stations, and the medium for cutting or connecting the pipeline media is suitable for: Water, steam and other non-corrosive medium forging steel valves compared with other valve products are characterized by high temperature and high pressure, unique self-sealing design, the higher the pressure, the more reliable the seal. Due to the technical characteristics of the performance, the special conditions of the working conditions make the product also form a feature that cannot be replaced by other products. Features and benefits ● A compact but extremely sturdy design for high pressure-temperature service. ● Solid CoCr alloy wedge (optional) ensures low friction and long service life. ● For Class 1500 valves and for steam service, seats are seal-welded to the body. ● Packing rings are Precompressed to 4000 psi to provide a high integrity seal. ● For welded bonnet valves, the bonnet is threaded in and torqued to an engineered torque value and the body bonnet joint is strength-welded, offering double protection against leakage. (Body/bonnet threads and strength-weld). ● Fully guided wedge reduces wear on seating surfaces. ● Repairable 2-piece stem drive. ● Parallel slide gate valves also available. ● Optional design available with double packing, leak-off connection, live-loading and a packing blowout for easy removal of old packing. Technical specification: ●Design: API 602,BS5352，ANSI B16.34 ●Connection ends: a.Scoket welded ends conform to ANSI B16.11 b.Screw ends conform to ANSI B1.20.1 c.Butt-welded ends conform to ANSI B16.25 d.Flanged ends conform to ANSI B16.5 ●Test & inspection: API 598 ●Structure feature: Bolted bonnet, outside screw and yoke. Welded bonnet,outside screw and yoke. ●Body materials: A105, F11,F22,304,304L,316,316L

24 Inch API 600 Carbon Steel Flanged Gate 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. The gate faces can form a wedge shape or they can be parallel. Typical gate valves should never be used for regulating flow, unless they are specifically designed for that purpose. On opening the gate valve, the flow path is enlarged in a highly nonlinear manner with respect to percent of opening.

The 900LB High Pressure Seal Bonnet Gate Valve is mainly used as an opening and closing device on the water and steam pipelines for cutting or connecting the medium in the pipeline. It should be fully open or fully closed during use and cannot be used as a regulating valve. Working principle of power station gate valve: Turn the hand wheel or stem nut clockwise, the valve stem drives the gate down, so that the sealing surface is matched, the channel is cut, that is, it is closed; otherwise, it is open. 900LB High Pressure Seal Bonnet Gate Valve features: 1. Pressure self-tightening seal is adopted, and the two ends of the valve body branch are welded. 2. The valve seat and valve sealing surface are made of cobalt-based hard alloy plasma spray welding, which has good wear resistance and scratch resistance. 3. The valve stem is treated by corrosion-resistant nitriding, which has good corrosion resistance and scratch resistance. Please contact our [email protected] for other materials and details.

API 600 1500 LB Pressure Seal Gate Valve is in accordance with API 600, the High Pressure Seal Gate Valves has a beautiful shape, compact structure, reliable sealing. Valve for the Class 900 lb-Class 2500 lb various tubes on the road. High-pressure self-sealing valve has the following advantages: The pressure seal valves are designed for service of high temperature and high pressure and are widely used in fossil fuel power plant. Compared with bolted bonnet joint valves, it provides absolute reliable sealing of the bonnet joint, so that the pressure seal valves are more compact and rigid as well as maintenance cost-effective at high temperature and high pressure service. This kind of gate valve is not only characterized as simple structure and reliable usage, but also able to create slight flexible deformation to compensate the deviation of the sealing face angle generated during processing, thus improving the process performance. In addition, at seat and gate disc seal surface are over-lay with iron-base alloy or Co-base alloy or carbide alloy for long duration.
