Hastelloy Plug Valve

The GMK Hastelloy plug valves have exceptional anti-corrosion properties in environments with both high oxidative erosion and reductive acidic environment. GMK Hastelloy plug valve is utilized extensively within the chemical processing field. Plug valves are an outstanding product for a broad range of commercial and light industry sectors. Some of these applications include directional access controls, the ability to handle gas or liquid fuel sources, the regulation of liquids with dissolved particles, such as cement slurry, and the management of low-pressure, low-temperature offerings. Plug valves are also an excellent choice for many other applications. GMK Plug valves are used in a wide variety of industries and system configurations because of their smooth design, continuous service possibilities, leak-tight service, minimum resistance to flow, and multi-port layout choice availability.

  • Plug valves provide several benefits in addition to their small size and reduced profile, including the following:
  • Stream Regulation provides a secure shut-off, a rapid reopening, and a limited pressure decrease.
  • Because the real plug and the body seating surface are not accessible to the line fluid, there is a lower risk of rust or erosion occurring. This contributes to the longevity of the product.
  • It has Superior resistance to cracking caused by stress and corrosion.


The valve seat may be easily replaced in the event of damage. It’s anti-static and helps avoid fires.


The steam from the valve is utilized to keep things from going awry, and the valve also includes a safety lock feature to keep anything from escaping. Used in acetic aid, chemical engineering, aircraft, and any other corrosive media imaginable.
