The Y-shaped bellows globe valve adopts a straight-through and direct-flow structure. This structure features low fluid resistance
○ Nominal diameter: DN15–DN200mm
○ Nominal pressure: PN16–PN200 (or Class150–Class600)
○ Applicable temperature: -29℃ to +450℃ (adjustable based on sealing and material)
○ Connection method: Flange connection (RF/FF/MFM) and welding end (BW/SW) are optional
○ Valve body material: WCB, WC6, CF8, CF8M, A105, F304, F316, etc
○ Bellows material: 316L, Inconel 625, Hastelloy C-276 (optional)
○ Sealing form: dual sealing with metal bellows and packing, zero external leakage design
○ Valve disc/seat sealing surface: build-up welding of stellite alloy or body hardening treatment
○ Operating mode: handwheel, bevel gear, electric, pneumatic (optional)
○ Applicable medium: steam, heat transfer oil, high-temperature water, corrosive chemical media
○ The Y-shaped flow channel design reduces pressure loss and enhances the efficiency of medium circulation.
○ The fully sealed structure of the corrugated pipe ensures zero external leakage, making it safe, environmentally friendly, and reliable.
○ The valve disc is guided precisely and stably, ensuring smooth opening and closing and enduring frequent operation conditions.
○ Resistant to high temperature and high pressure corrosion, suitable for a variety of harsh industrial media environments.
○ Compact structure with high strength, and long service life due to resistance to thermal fatigue and mechanical wear.
○ The main high-temperature steam pipeline requires control points with low flow resistance and high sealing performance.
○ Block valves for corrosive media in chemical plants in a compact layout.
○ Key regulating positions of boiler feedwater and bypass systems in the power industry.
○ On-off control valve for the heat transfer oil circulation heating system under high-temperature operating conditions.
○ Situations where zero leakage is required in clean pipelines in the pharmaceutical or food industry.
