Bellows Globe Valve

The Y-shaped bellows globe valve adopts a straight-through and direct-flow structure. This structure features low fluid resistance

Parameter

○ 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


Performance

○ 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.


Application

○ 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.
