For adjusting the flow rate of air for gas burner combustion. Available in a "manual type" with a lockable opening and a "control type" that can be linked to a control motor.
The SHOEI Butterfly Valve Series features butterfly valves with an opening degree indicator for flow adjustment. The BVM "Manual Hand-operated" model allows the opening degree setting to be fixed with a locking screw and has a full-port design that minimizes pressure loss. The BVC "Control Valve" can be linked with control motors (compatible with various manufacturers) and offers a wide range for reduced port and handle adjustments, providing high flow control performance. 【Product Specifications】 ◇ The fluid used is air (for combustion), city gas (13A, natural gas, LNG), and propane gas (LPG). ◇ The fluid temperature is below 60°C. ◇ The fluid pressure is below 10 kPa. (Please consult us if you are considering specifications outside of the above.)

Company information
Since its establishment in 1959, Seiei Manufacturing Co., Ltd. has supplied gas burners and industrial furnaces to various fields. Leveraging the "combustion technology" and "thermal utilization technology" developed during this time, we are working on the development of "hydrogen and ammonia combustion technology" and "low-carbon thermal equipment." At the "Thermal Technology Research Institute," we can conduct combustion tests of hydrogen gas burners, as well as tests for painting drying and aluminum melting using hydrogen combustion. Additionally, we can perform various tests to solve issues related to thermal equipment. As professionals in thermal equipment, we are committed to contributing to the realization of carbon-neutral manufacturing.
