This product is an LSA type pneumatic throttle valve that integrates air pipe connection and air flow rate pressure regulation. Adopting a throttle valve design, stepless speed regulation can be achieved by rotating the adjustment knob, smoothly controlling from fully closed to fully open. One joint only matches one type of tracheal outer diameter, using an insertable connection without the need for threaded sealing or heating tools. The release ring design allows for easy disassembly by pressing, making it convenient for maintenance. The LSA type design is compact in size and suitable for installation in narrow positions in the air path., Manufacturer: wenwendianzi
