Large Air Flow Control Valve（FCVR）
Space saving: There is no need for straight pipe sections before and after the air valve, which can be directly installed downstream of elbows or tees. It can be installed horizontally, vertically, or obliquely, and the air volume measurement and control performance is not limited by the installation posture
High airtightness: The valve body leakage reaches Class A, and the valve plate meets the leakage requirements of ordinary air valves (according to JG/T 436-2014 "Building Ventilation Air Volume Control Valves" standard)
Valve body material: Made of 304 or 316 stainless steel, fully welded, fire-resistant, resistant to high and low temperatures, and corrosion-resistant
Pressure independent: measurement deviation of air volume ≤ 3%, control deviation ≤ 5%
Controller: Supports RTU485 communication mode and can be integrated with the control system
