Butterfly valves / Leakage butterfly valves - Mrt Process

Butterfly valves / Leakage butterfly valves

Butterfly valves / Leakage butterfly valves

Butterfly valves are preferably installed on panels to minimize costs and close the tank. These valves come with various connection options but can also be used as an intermediate flange. KIESELMANN's stainless steel valves offer the highest quality, dimensional balance, and surface roughness in their class. KIESELMANN's seals have a long service life due to dimensional optimization. 

  •  ► Easy installation
  •  ► Ergonomic temperature control button (Several color options available)
  •  ► Structure designed for easy maintenance
  •  ► Flow/leakage protection to prevent costs (Butterfly valve leakage)
  •  ► Choice of automation
  •  ► Three different actuator options - Suitable for PDA75 / PDA 100 / PDA 125 connections
  •  ► High torque actuator options
