This assembly is based around a Sirca International AP06S08BH2BIS pneumatic rotary actuator. It is designed to provide approximately quarter-turn movement for the automated opening and closing of industrial valves. Typical applications include butterfly valves, ball valves and other process valves requiring a rotary actuator.

The actuator uses a spring-return configuration with 8 springs. This type of arrangement provides a mechanical return action when pneumatic pressure is removed, allowing the valve assembly to be configured for a defined fail position depending on the valve and mounting arrangement.

The actuator nameplate specifies a maximum pneumatic pressure of 10 bar / 145 psi and an operating temperature range of -20°C to +80°C. The identification plate gives traceability code 20003500, year 2020 and mounting variation A.

The actuator carries CE, EAC and hazardous-area markings. A SIL 3 / IEC EN 61508 marking is also shown on the actuator identification label, making the unit suitable for applications where specified functional-safety requirements are relevant, subject to correct system design and installation.

Mounted on the actuator is an HKC APL-510N valve position monitor. This unit provides visual and electrical monitoring of the actuator or valve position and is fitted with a prominent dome-style OPEN / CLOSED position indicator. This allows the valve position to be checked locally while also providing a housing for electrical position feedback.

The HKC APL-510N is marked for use in hazardous locations and carries both ATEX and IECEx certification information. The nameplate shows ATEX certificate EPS 14 ATEX 1764X and IECEx certificate IECEx EPS 14.0094X. The enclosure is marked IP67 and the stated ambient temperature range is -20°C to +60°C.

Hazardous-area markings shown on the position monitor include II 2G Ex d IIC T6 Gb for gas atmospheres and II 2D Ex tb IIIC T85°C Db IP67 for dust atmospheres. Corresponding IECEx markings are also shown on the identification plate.

The assembly also includes the visible pneumatic and electrical connections required for integration into a valve automation system. The combination of a spring-return pneumatic actuator and certified position monitor makes this unit suitable for process-industry valve control where automatic operation, defined fail positioning and remote position feedback are required.
