The BZD series valves are semiconductor-grade butterfly valves that are based on conventional industrial butterfly valves but were perfected by applying KITZSCT’s original cleaning technology.

• Features :
  • The valve body and the parts in the wetted area are a wafer-shaped industrial butterfly valve made of stainless steel. The parts in the wetted area are polished and undergo oil-free processing in order to minimize particle accumulation and adhesion.
  • Because the valves adopt a double eccentric structure in which the stem’s center of rotation deviates slightly from the disk seal surface as well as the center of the disk (pipe), there is no contact between the disk and seat ring when the valve is fully open, which prevents deformation of the seat and excessive abrasion to ensure a high level of sealing capability.
  • Giving more width to the disk and seat ring seal surfaces improves the sealing capability, and the valves can be operated with a small opening/closing torque because excess swaging is not necessary.
  • The seat material is durable PTFE. In addition, cracking, peeling, or excessive abrasion will not occur in the seat ring because it has a double eccentric structure with fully uniform seal contact pressure, appropriate swaging force, etc., forming a structure that will withstand long-term use.
  • Use of the gears in the actuation mechanism requires only small amount of force.It also takes up less footprint than conventional lever operated valves.
  • A pneumatic actuator can be mounted by using a bracket and connector.

• Technical characteristics :
  • Stainless steel butterfly valve.
  • The parts in the wetted area are polished and undergo oil-free processing in order to minimize particle accumulation and adhesion.
  • Size : From 50 to 400 A.
