Product Features

Precise outlet pressure control with wide application range; simple valve core maintenance. Pressure regulation and safety shutoff can be integrated into one unit. No installation or commissioning required for the actuator and valve head, facilitating on-site maintenance. The residual gas of the indicator is not discharged to the outside; simple operation and easy on-line maintenance. High-efficiency noise reduction design. Compact structure and easy installation.

Applicable Media

Natural gas, manufactured gas, liquefied petroleum gas, air and other non-corrosive gases. Suitable for city gate stations, regional pressure regulating stations, industrial furnaces, boilers and gas supply systems for large public users.
