ExLin.

A mechanical conversion kit that adds a linear stroke to an ExMax/RedMax/InMax-F rotary actuator for direct operation of valves. The kit has its own IECEx certificate; power supply and control are provided by the base actuator.

Key features

Mechanical kit – no electronics, motor or control of its own
Mounts on an ExMax/RedMax/InMax rotary actuator, size S or M, exclusively the -F variant (spring return)
6 models by max. stroke: 7.5 / 10 / 15 / 20 / 30 / 42 mm
Anodised aluminium housing (AlMg4.5), stroke rod and adapter in V4A/AISI 316L stainless steel
Optional -CT variant with C5-M coating for marine environments
The valve adaptation is ordered to suit the valve manufacturer, type and nominal size DN

Applications

Globe (plug) valves 3-way valves HVAC control

ExLin is an add-on to the ExMax/RedMax/InMax actuator – power supply, control and feedback are all provided by the base actuator. Only the -F variants (spring return) are compatible, not the fast variants with a return time of 1 s (S) or 3 s (M).

Marking (IECEx)

Ex h IIC T6/T5/T4 Gb / Ex h IIIC T80/T95/T130 °C Db

ExLin is available in 6 models by maximum stroke. If the required stroke lies between two values, the manufacturer specifies that the next larger model is always used.

Model	Max. stroke
LIN-7.5	7.5 mm
LIN-10	10 mm
LIN-15	15 mm
LIN-20	20 mm
LIN-30	30 mm
LIN-40	42 mm

Designation overview

What the designation and optional suffixes mean

LIN-xx

Number = maximum stroke in mm (except LIN-40, which has 42 mm).

-F

The base actuator must be a spring return version – the kit does not work without -F.

-CT

Optional C5-M marine coating + stainless steel fittings for offshore applications.

IECEx – Ex h IIC T6/T5/T4 Gb

IECEx EPS 20.0029X

Separate certificate for the mechanical kit (no electrical circuits) – type of protection “Ex h” = constructional safety. Dust part: Ex h IIIC T80/T95/T130 °C Db.

Assembly certification

LIN + base actuator

The installed assembly is covered by both the ExLin kit certificate and the separate electrical ATEX/IECEx certificate of the ExMax/RedMax base actuator.
