Replacement of Satchwell "AL..S" series Spring Return Linear Actuator by S-E M700 Spring Return Linear Actuator due to obsolescence.(Actuator Selection)

Issue

Satchwell “AL..S” series Spring Return Linear Actuator requires replacement

Environment

Satchwell “AL..S” series Spring Return Linear Actuator installed on Satchwell MJF, MZ, MZF, VJF, VSF, VZ or VZF series Plug and Seat Valve Body.

Actuator type :- AL..S series.

Cause

Obsolescence of Satchwell AL..S series Spring Return Linear Actuator.

Resolution

  1. Replace Satchwell AL..S series Spring Return Linear Actuator with S-E M700 Spring Return Linear Actuator and Linkage Kit :
    AL..S = M700 + L7SV (880-0126-000) Linkage Kit.
    N.B.
    M700 is available with two different spring return actions
    M700 - SRSU (880-0430-000) = Spring Return Spring Up          ( M700 - SRSU will CLOSE a Satchwell Valve.)
    M700 - SRSD (880-0440-000) = Spring Return Spring Down     ( M700 - SRSD will OPEN a Satchwell Valve.)
  2. Should the Satchwell AL..S series Actuator include a wired Auxiliary Switch then the following S-E M700 Actuator specifications which include 2 independent 24 volt 4 amp AC-1 rated SPDT Auxiliary End Point Switches should be considered as appropriate:
    M700 - S2 - SRSU (880-0431-000)
    M700 - S2 - SRSD (880-0441-000)
  3. Alternatively Auxiliary Switch Pack S2 (880-0104-000) - Two independent 24 volt 4 amp AC-1 rated SPDT Auxiliary End Point Switches may be purchased separately permitting local installation. 
  4. Particular care should be taken when selecting a TAC Forta M700 Spring Return Actuator to replace an existing Satchwell ALMS, ALXS or ALES Spring Return Actuator.
