Its straight-through valve body design facilitates easy trim replacement and features column-oriented unbalanced valve trim. Specifically designed for chemical or hydrocarbon treatment scenarios, it excels in controlling non-lubricated or viscous liquids. Metal-to-metal seals ensure reliable performance across large pressure differentials and temperature variations, while an option for metal-to-PTFE seals ensures tight shutoff where needed. The valve embodies efficiency and adaptability in demanding industrial environments.
Available in port sizes ranging from DN25 to DN50 (1 Inch to 2 Inch) and pressure ratings from PN25 to PN32 (Class 1500 LB to 2500 LB), this pneumatic boiler blowdown control valve is engineered to handle water, steam, and gas mediums. It serves as an anti-cavitation multi-stage pressure reduction valve, featuring a specially designed trim that facilitates incremental fluid pressure reduction, thus controlling fluid velocity to prevent cavitation damage. The trim's separable throttling part enhances sealing face protection, while the hardened surface treatment ensures durability with a hardness of approximately HRC70. Notably, a large notch on the plug surface prevents blockage from granular fluids. With excellent erosion resistance and prolonged service life, this valve offers an optimal solution for intermittently eliminating insoluble sediments and impurities from boiler water in power plants.
Available in sizes ranging from DN15 to DN300 (1/2 Inch to 12 Inch) and pressure ratings of PN10, PN16, and Class 150 LB, this pressure reducing valve, crafted from ASTM A216 WCB material, is a precision instrument for micro (differential) pressure regulation. Operating without external energy, it harnesses the controlled medium's energy to actuate the valve, controlling the plug's position to adjust interception area. This alteration modulates upstream and downstream differential pressure and flow rate, ensuring stable downstream pressure (control downstream pressure type) or relief pressure (control upstream pressure type). Boasting sensitive response, superior sealing, and minimal pressure fluctuations, it finds extensive use in micro-pressure control applications across diverse industrial equipment.
The eccentric rotary plug control valve features a one-piece body design and connects via flanged (ASME Class 150 / PN25) or wafer type (ASME Class 150 / PN25) connections. Made of ASTM A216 WCB material, it incorporates an eccentric plug that remains slightly apart from the valve seat until near closure, allowing dynamic alignment for effective shut-off. Ideal for handling mediums like slurries, grit, or solids, these valves offer superior control accuracy and wide rangeability. They're often equipped with pneumatic actuators, digital/smart positioners, and air filter regulators for precise flow control, making them versatile solutions for various industrial applications.
The eccentric rotary plug control valve boasts a one-piece body design, adaptable for connection via flanged (ASME Class 150 LB / PN25) or wafer type (ASME Class 150 LB/ PN25) configurations. This valve type features a uniquely shaped plug that maintains a slight distance from the valve seat until near closure, enhancing dynamic alignment for optimal shut-off. Commonly referred to as eccentric plug valves, they incorporate a plug-shaped component following an eccentric path during rotation. This design ensures minimal contact between the plug and seat until just before closure, facilitating precise cutoff as sealing surfaces dynamically align. Widely employed in applications handling slurries, grit, or solids, these valves offer superior control accuracy and wide rangeability, complemented by pneumatic actuators, digital/smart positioners, and air filter regulators for meticulous flow control.
The pressure regulating valve, a crucial nitrogen sealing apparatus, consists of a control valve, actuator, pressure spring, pilot, pulse pipe, and ancillary components. Its primary function is to uphold gas pressure, typically nitrogen, atop a vessel, thereby averting material exposure to air, preventing volatilization and oxidation, and ensuring vessel integrity. Especially adept for safeguarding gas containment systems in sizable storage tanks, this product boasts energy efficiency, swift responsiveness, dependable operation, and user-friendly maintenance. Its versatility extends across various sectors including petroleum, chemical industries, among others, where it finds widespread application.
