Supplier product
Zhejiang Lianggao Valve Co., Ltd.
Large-diameter damper for comparatively low-pressure flue-gas piping.
This vent butterfly valve uses the supplier’s four-bar arrangement for flue-gas lines. Lianggao places it in chemical, metallurgical and mining applications rather than its slurry knife-gate selection. The catalog lists soft and hard sealing schedules and multiple drive choices, allowing the configuration to be discussed around the gas temperature and the required isolation duty.
