Satchwell "AMS" and "AMSH" series Spring Return Rotary Actuator requires replacement by S-E M700 Spring Return Linear Actuator due to obsolescence.
- Satchwell "AMS" series Spring Return Rotary Actuator installed on Satchwell MJF, MZ, MZF, VJF, VSF, VZ or VZF series Plug and Seat Valve Body.
- Satchwell "AMSH" series Spring Return Rotary Actuator installed on Satchwell MZF or VZF series 125mm and 150mm Plug and Seat Valve Body.
- Where a Satchwell "AMS" series Spring Return Rotary Actuator is installed on a Satchwell VV Butterfly Valve Body then NO simple Actuator replacement is available.

Obsolescence of Satchwell AMS and AMSH series Spring Return Rotary Actuator.
- The new actuator is 24Vac and the control signal will need to be converted from 230Vac to 24Vac, this could be achieved by a transformer and 2 off 230Vac relays. The old signals switch the coils of the relays. The relay contacts switch 24Vac to the new actuator.
- Replace Satchwell AMS or AMSH series Spring Return Rotary Actuator with S-E M700 Spring Return Linear Actuator and Linkage Kit:
AMS = M700 + L7SV (880-0126-000) Linkage Kit.
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.)
- Should the Satchwell AMS 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)
- 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.
- Particular care should be taken when selecting a TAC Forta M700 Spring Return Actuator to replace an existing Satchwell AMS Spring Return Actuator.
