single seat type control valve

GMK has the best sanitary single-seated valves. Because it offers a secure seal and has a lower chance of leaking, the single-seat valve manufactured by GMK is the most suitable option for modulating service. When compared to other types of valves, a single-seat valve’s ability to control the flow of fluid through it is far simpler. The carbon steel, stainless steel, and other types of steel used in their construction are of the highest grade. It has specialized cages that can be given with noise reduction and anti-cavitation functions according to the requirements of various service situations.

GMK’s sanitary single-seated valves come standard with a positioner that can perform either the role of a position controller (PD) or a process controller (PID). It is able to flow, has a modest pressure loss, and has a performance that has been regulated. Pneumatic diaphragm actuators and pneumatic piston actuators are the types of actuators that are used in the construction of these valves. It comes with the normal bonnet type, as well as the heat dissipation type, the cryogenic type, and the bellows type.



  • It is also able to handle circumstances involving slurry polymer crystals and high-temperature fluid, making it suitable for usage in high-pressure scenarios.
  • This control valve has the benefits of simple construction and is easy to operate, making it an efficient and cost-effective choice.
  • It is both lightweight and compact, and it has a compact structure.
  • It is very useful for managing fluids that have a high viscosity, as well as granules and suspended materials, and it has the ability to prevent coking, bonding, and blockage.
