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

Technical Data

Control function (Cf.):

217.30:

217.25:

Pneumatically operated

Fail safe close (NC): Cf. 1 & 4

Fail safe open (NO): Cf. 2 & 5

Double acting (DA): Cf. 3 & 6
At control function NO/DA higher control
pressure than required may affect
the lifetime of the working diaphragm.

Direction Control connection:At Cf. 4, 5 & 6 in flow direction, standard
At Cf. 1, 2 & 3, 90° to flow direction

Max. working pressure:

217.30:

 

217.25:

Unidirectional (delta p = 100%)

Cf: Fail safe close
EPDM diaphragm 8 bar (115 psi)
PTFE diaphragm 7 bar (100 psi)

Cf: Fail safe open and double acting
EPDM diaphragm 8 bar (115 psi)
PTFE diaphragm 7 bar (100 psi)

Higher working pressure may be achieved with different actuator.
Please consult a SED factory representative for working pressure above the indicated maximum.

Max. working temperature:160°C (320°F) dependent on application

Control pressure:

217.30:

217.25:

Cf. 1 & 4 4 - 7 bar (60 - 100 psi)
