RQJ/*/* F-QZFS* series axial flow shut-off valve
The RQJ/*/*F-QZFS series gas safety shut-off valves are axial flow structure safety shut-off valves. This series of products has a flow path direction that is consistent with the pipeline gas flow direction, featuring advantages such as high flow capacity, high precision, good sealing performance, and fast response speed. It can achieve overpressure and low-pressure protection functions. Applicable media: natural gas, artificial coal gas, liquefied petroleum gas, and other non-corrosive gases.
RQJ/*/*F-QZQS* series gas safety shut-off valve
The RQJ/*/*F-QZQS series gas safety shut-off valves are used in gas transmission and distribution systems. When the pressure of the pipeline controlled by the shut-off valve is higher or lower than the set shut-off pressure, the RQJ safety shut-off valve can urgently cut off the gas flow in the pipeline to protect downstream equipment. Applicable media: natural gas, artificial coal gas, liquefied petroleum gas, and other non-corrosive gases.
RFZ/*/0.4L-QZF* series exhaust valve
The RFZ/*/0.4L-QZF* series relief valve is a direct-acting relief valve, primarily used as a safety device in medium to low pressure regulating systems. When any abnormality in the system causes the monitored pressure to reach a predetermined warning value, this device quickly and automatically relieves the pressure, stabilizing it within a specified range. This series of products features a compact structure, fast response, reliable performance, and good sealing capabilities.
