NPT Needle Valve Introduction

The sealing materials of internal thread needle valve include tetrafluoro seal, red copper seal and cemented carbide seal. Special structure and corresponding seal can be adopted according to different pressure and temperature. 

The pressure test adopts 1.5 times of the working pressure to ensure that the valve will not leak under the working pressure and that the seal will not deform under the corresponding temperature, No loose sealing will occur.
