RTJ-SQ Pressure Regulator is an indirect-acting regulator. This regulator has a built-in balance valve and a safety shut-off device. It combines pressure control and safety shut off function. RTJ-SQ pressure regulator can reduce the upstream pressure to a steady downstream pressure. When malfunctions, it can limit the downstream pressure within a safe range. It is very safe and reliable.

This product has a special noise reduction design, which can effectively reduce the noise at work. Compared with common gas regulator, it has higher regulative precision and larger flow capacity. RTJ-SQ pressure regulator has superior performance. The internal corrosion-resistant materials ensure its long service life. It has high sensitivity, good accuracy and fast response, besides, its on-line maintenance is very easy and simple. This regulator is widely applied in city gate station, regional regulator station, gas pressure regulator box and pressure regulating cabinet.
