Plug 3-way valve 11b38bk for pressure gauge with flange Pn 16

Three-way valves 11b38bk with a pressure rating of 1.6 MPa (16 kg/cm2) are used to connect a pressure gauge to a pipeline. These valves are made of brass with a nominal diameter of DN15. They have a 1/2" G thread at the inlet and M20*1.5 metric thread at the outlet for connecting a pressure gauge without an adapter. The 11b38bk valves allow you to release excess pressure and shut off the pipeline when removing the pressure gauge. The sealing of the cone plug is provided by tightening the nut on the lower part of the valve.

The flange is used to check the installed pressure gauge using another (known to be correct) pressure gauge.

The absence of a handle is not always a disadvantage and can prevent inappropriate actions by outsiders if the valve is installed in a public place.
