Optional adders upon Customer" request

Ambient temperature:

Standard range: - 30 .. + 100 °C

Low temperature design: -40 .. + 100 °C

Extreme low temperature design: -60 .. + 100 °C

High temperature application even up to 160 °C

Deviations from choices listed above can be checked upon Customer' request

Manual Override options for single-acting actuators:

By Mechanical Jackscrew - marked M (visible jackscrew)

By Mechanical Jackscrew - marked MH (jackscrew + protection pipe)

By Mechanical Jackscrew - marked MHD (jackscrew + protection pipe+ declutchable handwheel)

Hydraulic type solutions - for details ask for the relevant factory catalouge sheet

Type Code designation:

G - type by scotch-yoke mechanism for proper adaptation to valve torque characteristic

P/H- Working fluid classification - P for pneumatic/ H for hydraulic type

Based on the size of center body:

085/ 100/ 130/ 160/ 161/ 200/ 201/ 270/ 271/ 350 are available

- For further details and examples ask for the relevant factory catalouge shee 

Design of scotch-yoke mechanism:

Symmetrical yoke design - Torque peaks values are similar in both end positions (close/ open valve)

Canted yoke design - Actuator torque output has only one peak in one of the end position

- canted type can REDUCE: actuator size/ weight/ cost at some valve application

Size of working cylinder (e.g.: 100)

Seals for GP and GH range: 

NBR - 30 .. +100 °C

Viton  -20 .. + 100 °C

Fluorosilicone  -40 .. + 100 °C/ OR down to -60 °C  - by different code marking either at GP or GH 

(e.g. GP by NBR seal is marked as "A" / GH by NBR seal is marked as "F")

Cylinder/ Spring Canister Configuration:

Spring Return - fail to CLOSE 

Spring Return - fail to OPEN 

Double acting actuators:

D1 - DA actuator by 1 pc of cylinder

D2 - DA actuator by 2 pc of cylinder 

Comprehensive Control System:

Set of equipment as a full control package (soleonid valves, positioners, connection piping and fittings, exhaust valves, pneumatic-hydraulic manifolds etc.)

Equipment are mounted in cabinet or panel

Cabinet or panel on the actuator surface

Cabinet or panel in a remote location from distance of actuator
