A pneumatic actuated ball valve combines a quarter-turn ball valve with a pneumatic actuator for automated isolation, flow diversion or modulating control, depending on the valve configuration. Speciality Valve manufactures and supplies pneumatic actuated ball valves in trunnion, floating, two-piece, three-piece and three-way configurations for process and pipeline service. Valve and actuator selection should consider valve size, differential pressure, operating torque, air-supply pressure, process temperature, material compatibility, operating frequency and required fail position. The available configurations cover different piping, pressure and flow-path requirements: Pneumatic Trunnion Forged Ball Valve – Forged-body trunnion construction selected according to pressure class, material specification and project requirements. Pneumatic Casting Trunnion Ball Valve – Cast-body trunnion design for industrial isolation duties. Pneumatic Actuated Two-Piece Ball Valve – Compact body arrangement for general process service. Pneumatic Actuated Two-Piece Flanged Ball Valve – Flanged configuration for equipment and pipeline connections. Pneumatic Actuated Three-Piece Ball Valve – Bolted body design allowing access for maintenance. Pneumatic Actuated Three-Piece Flanged Ball Valve – Three-piece construction with flanged ends for suitable piping systems. Pneumatic Actuated Three-Way Ball Valve – Used for automated flow diversion, line selection or mixing where supported by the selected L-port or T-port arrangement. Pneumatic Actuated Three-Way Flanged Ball Valve – Flanged three-way arrangement for larger pipeline connections. Three-way configurations can use suitable L-port or T-port arrangements depending on the required flow path. Connection and pressure combinations vary with valve size and construction. Pneumatic actuators are selected according to required valve torque, operating cycle, air supply and fail position. Single-Acting Actuator: Uses compressed air in one direction with spring return, allowing a specified spring-return position. Double-Acting Actuator: Uses compressed air for both opening and closing movement. Rack-and-Pinion Actuator: Rotary pneumatic actuator commonly used with compatible quarter-turn Ball Valves. Scotch-Yoke Actuator: Rotary actuator with a torque characteristic suited to selected high-torque quarter-turn valve duties. Required air-supply pressure should be taken from the selected actuator design and available plant-air conditions; typical industrial actuator packages may operate within approximately 4–8 bar. Solenoid valves, limit switches, positioners and manual overrides can be incorporated according to the automation arrangement. Material selection depends on process medium, pressure, temperature and corrosion conditions. Body, ball, stem and other wetted components should be selected as a compatible material system for the process medium, temperature, pressure and corrosion conditions. Seat construction influences leakage performance, temperature capability and media compatibility. PTFE / Reinforced PTFE – Used for compatible process fluids and general chemical service. PEEK – Selected where the required temperature, pressure and mechanical conditions exceed the limits of conventional PTFE-based seating. Metal Seat – Selected for suitable high-temperature, abrasive or severe-service duties where soft seating is not appropriate. Fire-Safe Construction – Available where the applicable project specification requires fire-tested construction. Anti-Static Arrangement – Used where static-charge dissipation is required. Fire-safe construction and anti-static arrangements are configuration-specific features and are not standard on every valve. Depending on valve construction and application, applicable standards may include: API 6D – Applicable pipeline Ball Valve designs. ASME B16.34 – Where applicable. ASME B16.10 – Face-to-face dimensions where applicable. ISO 5211 – Quarter-turn actuator mounting/interface. API 598 / ISO 5208 – Applicable pressure and leakage testing. API 607 – Fire testing for applicable fire-tested designs. ISO 15848 – Fugitive-emission requirements where specified. Testing may include: Shell pressure testing Seat leakage testing Valve cycling Actuator functional testing Torque verification Material verification Dimensional inspection Open/close functional test Full 90° travel verification Actuator torque/setting verification where applicable Air-supply and pneumatic-function check Fail-position test where applicable Solenoid and limit-switch function check where provided Positioner calibration/response check for modulating service Manual override check where provided Hydrocarbon Transfer Lines – Automated isolation of transfer and terminal piping. Compressor Systems – Automated isolation on suitable suction, discharge or bypass piping. Tank Farm Piping – Automated isolation during storage and product transfer. Chemical Process Lines – Isolation using suitable wetted materials and seats. Slurry or Solids-Bearing Service – Only selected Ball Valve and seat configurations where particle characteristics, abrasion, cavity behaviour and sealing design are suitable for the process.
