GB Standard Cast Steel Flanged Gate Valve – YONCO PN16 to PN160
The YONCO Cast Steel Flanged Gate Valve is a heavy-duty isolation valve engineered in strict accordance with the GB/T 12234 specification. Designed for demanding applications in petrochemical facilities, thermal power plants, and industrial piping systems, this valve provides reliable connect or shut-off operations for water, steam, oil, and chemical mediums. With its optimized flow channel and robust body rigidity, it minimizes pressure drop and ensures maximum flow efficiency, making it the trusted choice for critical fluid control.
Core Features & Advantages
- Robust Structural Integrity: Features excellent valve body rigidity, a compact footprint, and a streamlined flow path to maintain an ultra-low flow coefficient and prevent pressure loss.
- Durable Sealing Surfaces: Disc and seat sealing surfaces are hard-faced with premium stainless steel or hard alloy, delivering exceptional wear resistance, anti-galling properties, and a significantly prolonged service life.
- Reliable Stem Sealing: Utilizes high-quality flexible graphite or PTFE packing to ensure a secure, leak-proof seal that prevents fugitive emissions, while keeping operation exceptionally light and flexible.
- Versatile Wedge Options: Available in an elastic wedge single-disc structure, or rigid wedge single/double-disc configurations, engineered to automatically compensate for pipeline stress and high-temperature fluctuations.
- Multiple Actuation Modes: Standard configurations accommodate manual handwheel operations, with seamless integration available for gear transmission, pneumatic, and electric actuators based on automation requirements.
