For adjusting the airflow 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℃. ◇ The fluid pressure is below 10kPa. (Please consult us if you are considering specifications outside of the above.)
