DINKONDA GLOBAL Power Plants Special High Temperature And High Pressure Main Steam/water Supply Pipeline Butt Welding Connection Power Plant Globe Valve, One-way Shut-off Valve

Product Overview
This series of power station globe valves is mainly used in high-temperature and high-pressure main steam and water supply pipelines of thermal power plants. It adopts butt welding connection and self sealing valve cover structure, which can adapt to harsh working conditions of high temperature, high pressure, and temperature difference alternation. The valve has strong overall rigidity and stable sealing performance. When the system pressure increases, the sealing force of the valve cover increases accordingly. The higher the pressure, the more reliable the sealing. It is used for cutting off and opening/closing pipeline media and is the core supporting valve for power plant boilers and turbine auxiliary systems. It can also be used for high-temperature and high-pressure process pipelines in petrochemicals and metallurgy.

Structural Composition
1. Valve body: forged/cast power station specific valve body, with butt welding groove connection form, suitable for power station pipeline welding installation; Choose heat-resistant alloy steel materials such as WC9 and F91, which are resistant to high temperatures, creep, and withstand high-pressure impacts.

2. Valve disc and seat: The sealing surface is welded with Stellite hard alloy, which has high temperature resistance, wear resistance, and abrasion resistance. When closed, it is forcibly compressed to achieve a tight seal, suitable for long-term cyclic opening and closing of steam media.

3. Self sealing valve cover component: adopting a pressure self tightening sealing structure, the higher the medium pressure, the greater the clamping force of the valve cover gasket, and the sealing is reliable under high pressure conditions; Equipped with pressure bearing parts such as clamps and four in one rings, it does not require a large number of bolts to tighten the valve cover, making it easy for internal maintenance.

4. Valve stem: heat-resistant stainless steel valve stem, surface nitriding treatment, wear-resistant and high-temperature oxidation resistant; Clear stem structure, the position of the handwheel intuitively reflects the valve opening and closing stroke.

5. Execution bracket and handwheel: Portal bracket structure, stable guidance, reasonable force distribution of transmission mechanism; The blue steel handwheel is manually operated, closing clockwise and opening counterclockwise; Electric actuators can be selected according to project requirements to achieve remote control.

6. Packing component: High temperature flexible graphite packing, suitable for high temperature steam conditions, reducing the risk of medium leakage at the valve stem.

Product Features
1. Self sealing valve cover structure: relying on medium pressure to enhance sealing performance, stable and reliable sealing under high temperature and high pressure conditions, suitable for high-pressure steam systems in power plants.
The heat-resistant alloy steel body is resistant to high temperature creep and can withstand long-term continuous operation of high temperature and high pressure steam, adapting to the temperature and pressure fluctuations caused by power plant start-up and shutdown.

2. Hard alloy overlay sealing surface, resistant to erosion, wear, thermal shock, and has a long service life.

3. Butt welding connection, integrated with pipeline welding, with high overall structural strength and no risk of gasket leakage, meeting the specifications for power station pipelines.

4. The visible opening status of the visible pole allows for intuitive judgment of the valve switch position on site, facilitating operation and inspection.

5. Configurable electric drive, compatible with remote control of power plant DCS system, to meet the needs of automation units.
