The ZTMR6-L6-D combined pressure regulating valve is composed of two two-position three-way reversing valves and a pressure regulating valve in parallel. It is a very critical main control valve in the gas valve for oil workover rigs. It is connected to the reversing valve, and the pressure of the C port can be increased with the increase of the handle angle, and the handle can be positioned.
ZTMR6-L6-F combined pressure regulating valve is composed of two two-position three-way reversing valves and a pressure reducing valve in series. Like ZTMR6-L6-D, it belongs to the more critical valve parts for the production of workover rigs. It is used in the three-position five-way reversing valve, and the pressure of the A and B ports can be increased with the increase of the handle angle, and the handle can be automatically reset to the neutral position.

5. Outline and installation dimensions:
*The symbols in brackets indicate the handle position of ZTMR6-L6-F.
*P means that when the handle is in the corresponding position, the working air port has corresponding pressure air output.
When Pi represents the corresponding handle position, the working air port has corresponding air output of different pressures.
None: Indicates that there is no air pressure at the working air port corresponding to the handle position.
