Concentric Resilient Seated Butterfly Valve

GMK is a rising manufacturer of valves. The most fundamental kind of GMK butterfly valve is the resilient seated butterfly valve, which is also sometimes referred to by the name concentric butterfly valve. Because the head is positioned such that it is positioned in the center of the valve plate, it makes a significant amount of contact with the rubber seat to create a seal. Seats may be joined to the body in a variety of ways, the most common of which are dovetail connection seats, cartridge seats, and bonding seats. Valves are always constructed with the utmost attention to detail by our company.

GMK Butterfly valves with durable seats are of the negligible offsetting kind, meaning there is no offset towards the head. They are responsible for handling both liquid and gas applications. The GMK concentric resilient seated butterfly valve with loose liner is suitable for a broad variety of applications, including those involving the purification of sewage, as well as those involving the use of fluid in manufacturing environments.


In comparison to the sphere, globe, gate, and plug valves, GMK butterfly valves have several benefits that make them the superior choice for valve operations.

  • GMK concentric resilient seated butterfly valve is affordable, suitable in size, and lightweight.
  • They have a low number of moving components the required amount of care may be reduced to the barest essentials.
  • In addition to providing precise control over the flow of fluid, GMK butterfly valves are also very good at regulating pressure.
  • Throughout functioning, they suffer just a little decrease in pressure, and the fluids regain their momentum almost immediately after passing through the valve.


  • The centered variety, sometimes known as the middle line, has a hermetically sealed bubble.
  • Rapid setup and little upkeep. Mounting options are flexible.
  • Compact design, simple on/off switch at 90 degrees, low torque, high efficiency.
  • The disc’s two-way bearing means it may pass a pressure test with no leaks.
  • Cover flange ISO5211 as an alternative to
  • Anti-aging, corrosion-resistant, long-lasting, etc. Sealing materials are also brushed and washing resistant and may function in harsh environments.
  • Durability with time
