Rubber

Rubber sealed gas gate valve

Nominal pressure:≥PN1.6
Nominal diameter:DN100~300mm

Application characteristics

It can only be fully opened and fully closed, and can not be adjusted and throttled. The dark rod elastic seat seal gate valve uses the whole valve package to produce deformation compensation to achieve a good sealing effect, which overcomes the phenomenon of poor seal, leakage medium and rust of the general gate valve, and more effectively saves installation space. The valve plate is fully coated and fully vulcanized with oil and gas resistant NBR synthetic rubber due to the compression resilience of the rubber, the double-layer bonding vulcanization process and the robust valve plate design, these characteristics give the valve excellent durability. The triple-safe stem seal system can be replaced with pressure, ultra-high strength stem and comprehensive anti-corrosion properties ensure unmatched valve reliability.


Elastic seat seal

The main sealing part is the integral ram covered by rubber, which produces a small amount of adaptive elastic deformation under the action of operating force and medium pressure, and forms an excellent sealing effect with the precision cast valve seat.
