Features
- High cycle stainless steel piston actuator Type 217.30 with double piston
- Compact design, the outside diameter of the actuator is the same size as the bonnet flange connecting diaphragm and body
- Advantages in multiport bodies and manifold valve assemblies
- Low control air volume, high switching speed
- High repeatability
- Control air connection on the top, away from the process product line
- Direction of control air connection is mountable in 90° rotations
- CDSA sealing concept
- Flexible diaphragm suspension
- Clean and polished exterior design ideal for sterile wash downs
Optional
- Available with a wide range of control equipment and accessories
- Autoclavable
