PRF series gas pressure regulator with filter, through the spring setting regulation, keep the gas outlet pressure constant. When there is no gas flow, the zero flow shutdown function prevents the outlet pressure from rising.
The PRF series gas pressure regulator with filter maintains a constant outlet pressure by spring‑set adjustment and includes a zero‑flow shut‑off function. It is suitable for artificial gas, natural gas, LPG and non‑corrosive gases, and complies with EN88 standards. The regulator is offered in RP1/2", RP3/4" and RP1/6" thread sizes, with outlet pressure ranges from 10 mbar to 150 mbar.
The manual details professional installation requirements, including a 90° mounting orientation, a minimum 50 mm clearance from walls or floors, and a 400 mm space below the unit. It explains how to adjust outlet pressure using the adjustment screw, replace the filter element, and change the spring to achieve different pressure ranges. Routine inspection and leak testing are recommended to ensure safe operation. This manual is written in Chinese.
