1. Features:

The ZTMR6-L6-D combination pressure regulating valve is composed of two two-position three-way reversing valves and a pressure regulating valve in parallel. Through the reversing valve, and the pressure of C port can be increased with the increase of the handle angle, and the handle can be positioned.

The ZTMR6-L6-F combination pressure regulating valve is composed of two two-position three-way reversing valves in series with a pressure reducing valve. It is the same as ZTMR6-L6-D and belongs to the more critical valve parts produced for workover rigs. 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 automatically return to the neutral position.

 *The symbols in parentheses indicate the position of the ZTMR6-L6-F handle.

Function table:

*P indicates that the working air port has corresponding pressure air output when the corresponding handle position.

Pi indicates the corresponding handle position, the working air port has corresponding air output with different pressures.

None: Indicates that there is no air pressure at the working port corresponding to the handle position.
