Proportional flow regulator QKL-HS4 / -HS5

for gasfor airfor oxygen

QKL-HS5 is a 3-way electronic pressure regulator. It consists of a proportional solenoid, pressure transducer, intelligent electronics, and a refined spool. It features high flow rate, extremely fast pressure switching time, high accuracy, and compatibility with oxygen and hydrogen gas. Using the powerful in-house software, the control parameter can be customized, allowing users to build unique pressure profiles. It is available with analogue and digital command signals.
