601 Outer screw steel handle gas single nozzle valve

Product parameter: Specification (mm): Q21F-16T-15

Dunyun gas valves are strictly implemented according to the technical requirements and performance requirements of CJ / T 180-2014 Manual Gas Valves for Construction, and implement standardized management on the whole process from material testing, production control to performance testing, etc., which ensures that the quality of the whole manufacturing process is controllable and traceable, meeting the market requirements and national laws and regulations.

Product performance:

The main material of the valve adopts high quality brass national standard (HPb59-1 brand) to ensure the reliability of the material. Blank molding uses forging process for uniform density with no abscess, and it has long service life which is different from casting products. After fine finishing of the valve body and valve cover, high temperature annealing process should be adopted to effectively remove the internal stress caused by machining and improve the strength and corrosion resistance of the valve body. After many tests, it is proved that Dunyun brand valve has completely exceeded the torsion performance and bending performance requirements stipulated in the national standard.

Valve is equipped with EPDM O ring seal for high temperature and low temperature resistance, which can withstand-20℃ ~80℃ working temperature for a long time. The valve stem uses national standard HPb59-1 extrusion brass bar processing, and the sealing ball uses brass chrome treatment to maintain strong connection without leakage. Its good performance can be better reflected when in high temperature, low temperature, strong acid and alkali, oil and other harsh use environment.
