The Pisco pneumatic needle valve seamlessly integrates airflow throttling and open/close control. One end showcases a rotatable 8 mm push-in fitting designed for efficient tube connection, utilizing stainless steel claws for a secure hold. The opposing end features a R 3/8 inch male threaded port. Withstanding pressures from -1 bar (-14.5 psi) to 9 bar (130.5 psi), this valve not only handles air flow but also excels in vacuum applications. NBR seals ensure compatibility within a temperature range of 0 to 60°C (32 to 140 °F). Precision orifice adjustment is achieved through a rotatable needle, secured by a locknut. Clockwise rotation reduces flow rate, while counterclockwise increases it. Commencing adjustment from a fully closed state is advisable to prevent actuator movement. Excessive torque should be avoided during needle adjustment to maintain optimal flow characteristics. This valve is readily available in the United Kingdom.
