Assembly Scope Automation assemblies are supplied with actuator-mounted control components and monitoring devices suitable for site operating conditions and hazardous area classification.

Communication & Functional Capability • Communication interfaces such as Modbus or hardwired signals, where specified
• Position feedback and status indication
• Partial stroke testing (PST) capability for shutdown valves, where required
• Suitable for local and remote operation in accordance with project requirements

Compliance All automation packages are supplied in accordance with actuator manufacturer standards, project specifications, and applicable hazardous area and electrical certification requirements, with functional testing and documentation provided prior to delivery.

Controls & Accessories

Control and accessory components are supplied to enable monitoring, feedback, and reliable operation of actuated valves in field conditions.

Typical Scope • Air filter regulators (AFR) with gauges
• Solenoid valves
• Valve positioners (smart or conventional)
• Limit switch boxes and position feedback units
• Tubing, fittings, and manifolds
• Local control stations and junction boxes
• Weatherproof or explosion-proof enclosures
• Manual override systems
• Gearboxes and handwheel overrides
• Mounting brackets and couplings

Standards & Compliance

Applicable Standards • ISO 5211 actuator mounting interface
