The ZTMR6-L6-D combination pressure regulating valve is composed of two two-position three-way reversing valves in parallel with a pressure regulating valve. It is a very critical main control valve in the gas valve for oil workover rigs, which is equivalent to five-position six-position valve. Open the reversing valve, and the pressure of port C can increase 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, the handle can automatically return to the neutral position.
