About Actuator Controls & Spare Parts
Actuator controls and spare parts keep existing valve actuators running and let them connect to plant control systems. Seven Star LLC, an independent supplier in Muscat, supplies actuator controls, electronics and spares from AUMA, Masoneilan and ABB to maintenance teams in Oman and the GCC.
Types of actuator spare part in this category
Integral controls such as the AUMA MATIC AM, the explosion-proof AMExC and ACExC and the AC 01.2-SIL add local operation, fieldbus and functional safety to AUMA actuators, and FQM fail-safe units move part-turn valves to a safe position on power loss. Masoneilan spares include diaphragms for Type 87/88 and 37/38 actuators, standard, extended and ultra-low temperature kits, 50 series soft goods kits, and handwheel and limit stop options. ABB electronic units serve Contrac actuators.
How to select a actuator spare part
Identify the actuator model, size and serial number first, since spares are specific to each size and generation. For controls specify supply voltage, control interface, Ex rating and SIL requirement. For soft goods choose the temperature range kit that matches the service.
Data needed for a quotation

Frequently Asked Questions
Why does the serial number matter when ordering spares?
Actuator parts change between sizes and production series. The serial number lets the correct part be identified.
What is a fail-safe unit?
A module such as the AUMA FQM that stores energy and drives a part-turn valve to a defined safe position if power fails.
What does SIL mean for actuator controls?
Safety Integrity Level, per IEC 61508 and IEC 61511. SIL-rated controls such as the AC 01.2-SIL are used in safety instrumented functions.
How often should actuator diaphragms be replaced?
It depends on service conditions. Replace them during planned maintenance or when cracks, hardening or leaks are found.
What should I send for a quotation?
The actuator model, size, serial number and part number, or the control specification and quantity.
