Needle Instrument Valve

The CJ123 type is mainly composed of measuring valve, sampling valve and relief valve. Close the sampling valve and pressure relief valve, open the measuring valve medium counterclockwise to enter the pressure measurement. Open sampling valve, sampling and discharge. The outlet joint of the sampling valve can connect 12 nylon tubes or other process lines, such as changing the pressure gauge, closing the measuring valve and sampling valve first, because there is still pressure in the valve body, it is necessary to open the pressure relief valve gently to make the pressure meter slow down to zero, then unload the pressure gauge and avoid the operation. The spray of the medium is not only labor-saving, but also prolongs the service life of the pressure gauge. The CJN123 multi-function pressure gauge cut-off valve is the increase of the internal thread G1/2 "of the medium outlet pipe on the CJ123 series. The other functions are the same, and the entrance medium passes through the measuring valve from the outlet of the medium to the pipe as the cut-off valve, and the pressure, sampling, release, pressure relief, etc. are measured.

Multi-function pressure gauge cut-off valve features:

Small size, many functions.

It is easy to install, easy to operate, save investment and extend the life of pressure gauge.

It is stable in measurement and good in sealing performance.
