Attention:
At strokes between two values use the next higher linear unit (e.g. 24 mm stroke = LIN-30).
Limitation of resolution at YF-actuators with strokes < nominal (motor blockade)!
Note the maximum force of the actuator to prevent damage to your valve!
Info:
Details about suitable actuators with spring return see here
Nominal force (N) at spring of actuator in relation of max. stroke of LIN at temperatures between −20…+40 °C

Attention:
Blocking force in motor is round about 3 to 4 times larger than nominal force.

Attention:
Blocking force in motor is round about 1,5 to 2 times larger than nominal force.
Note valve dimensioning!
Above mentioned values are nominal trusts with performed self adjustment drive!
The maximum trusts can read values which are up to three to four times higher than values of tables! Without performed self adjustment drive there can occur much higher trust values, which can cause damages on the mentioned valve or linkages!
Delivery
- Linear unit, suitable for all ..Max-..-F actuators size S or M
Special models painted (coated) – ExMax-...-CTS / CTM (size S or M) + LIN-...-CT
- ExMax-...-CTS / CTM: Aluminium housing with seawater proof offshore/marine coating, resistant against corrosive and maritime atmosphere, some parts nickel plated
- LIN-...-CT: Aluminium housing with seawater proof offshore/marine coating, resistant against corrosive and maritime atmosphere.
Lifting rod, connecting parts and screws in stainless steel (VA) - Suitable for e.g. for offshore or onshore applications
Valve adaptation / neccessary accessories
- To select the right valve adaptation and get the right price information
the following data are required:
1. Valve manufacturer
2. Valve type
3. Valve nominal size (diameter) DN - For adaptations which are still designed by Schischek this data are minimum requirements
- To design new adaptations we need additional details of the valve body
as well as drawings - At purchase order you have to order both parts – actuator + adaptation
