Overview

Soft seal plug valves are often used in harsh environments such as corrosive, highly toxic and high hazard media, where leakage is strictly prohibited, and where valve materials will not pollute the media. According to the working medium, the valve body can be made of carbon steel, alloy steel and stainless steel.

Features

  1. 1.The friction coefficient of the sealing pair is small, the plug body functions flexibly, the service life is long.
  2. 2.There are window design and double-track groove sealing ring structures at the inlet and outlet of the valve body. The sealing pair reaches zero leakage.
  3. 3.Double-track groove sealing ring can not only make the bushing firmly located in the valve body without displacement, but also absorb the slight deformation of the bushing caused by changes in temperatures. Meanwhile, there are strong frictions between the bushing and the plug, which has the effect of automatic cleaning, improving the service life of the sealing surface.
  4. 4.It’s suitable for highly scouring medium of gas phase and liquid phase, such as PVC, urea, anhydride, and caustic soda production plant. Or, the medium that has a high requirement of external leakages, such as HF, phosgene, and so on.
  5. 5.The medium can flow in both directions, the installation direction is not restricted. Online maintenance can be achieved. It’s more convenient to use.
  6. 6.The unique design can prevent static electricity. It’s fireproof and thus is safe to use.
