Pneumatic Butterfly Valves are high-efficiency automated solutions designed for rapid-response flow control in modern industrial processes. By integrating a high-performance butterfly valve with a pneumatic actuator, these units provide reliable quarter-turn operation powered by compressed air. Available in both double-acting and spring-return (fail-safe) configurations, they are essential for applications requiring frequent cycling, remote operation, or emergency shutdown capabilities. The streamlined disc design ensures minimal flow resistance, making these valves an energy-efficient choice for large-scale liquid and gas handling systems.

Engineered to meet international standards such as API 609 and ISO 5211, our pneumatic butterfly valves are compatible with a wide range of control accessories, including solenoid valves, limit switches, and electro-pneumatic positioners for precise modulating service. The robust actuator housing is built to withstand harsh environments, while the valve bodies—available in wafer, lug, or flanged styles—are optimized for the demanding conditions of petrochemical plants, water treatment facilities, and power stations. Whether managing utility water or aggressive chemical media, these automated assemblies offer a cost-effective and low-maintenance solution for industrial automation across Jubail, Yanbu, and Dammam.



Pneumatic Butterfly Valves Features

  • » Automated Rapid Response: Equipped with high-torque pneumatic actuators for fast and reliable quarter-turn operation, ideal for high-cycle and time-critical process loops.
  • » Fail-Safe Operational Modes: Available in Double Acting or Spring Return configurations, ensuring the valve defaults to a safe position (Open or Closed) during a loss of power or air supply.
  • » Precise Modulating Control: Compatible with electro-pneumatic positioners (4-20mA) for accurate flow regulation and integration into automated control systems.
  • » Universal Mounting Interface: Features ISO 5211 top-work standards, allowing for the seamless mounting of various actuator sizes and standardized control accessories.
  • » Compact Automated Footprint: The integrated assembly maintains a low profile and reduced weight compared to motorized gate or globe valves, saving space in tight industrial manifolds.
  • » Corrosion-Resistant Actuator Housing: Actuators are constructed with hard-anodized aluminum or stainless steel housings to withstand the humid and saline environments of coastal industrial zones.
  • » Enhanced Monitoring: Supports the addition of limit switch boxes and visual indicators for real-time remote feedback of the valve's position to the central control room.
  • » Low Air Consumption: Optimized rack-and-pinion or scotch-yoke mechanisms provide maximum output torque with minimal instrument air requirements for improved energy efficiency.

Pneumatic Butterfly Valves Detailed Specifications

Valve Type Specifications/Description
Pneumatic Operated Butterfly Valve - Wafer Type Compact valve designed for installation between flanges, actuated by a pneumatic system. Ideal for tight spaces and offers efficient shut-off for fluid control in industrial applications.
Pneumatic Operated Butterfly Valve - Lug Type Features lug connections allowing for removal of one side without affecting the other. Actuated by a pneumatic system, this type is used in dead-end services and systems requiring ease of maintenance.
Pneumatic Operated Butterfly Valve - Double Flanged Designed with flanges on both ends for more secure and robust connections. Pneumatically operated for reliable control in high-pressure and high-flow industrial systems.
Pneumatic Actuator Operated Rubber Lined Butterfly Valve Rubber-lined valve for enhanced protection against corrosive media. Pneumatically actuated for efficient operation in chemical processing or water treatment systems.
Pneumatic Actuator Operated Double Eccentric Offset Disc Wafer Type Butterfly Valve Offset disc design reduces seat wear, providing improved durability and performance in high-pressure or high-temperature systems. Pneumatic actuation ensures remote operation for effective shut-off or control.
Damper Valve - Pneumatic Actuator Operated Used for regulating airflow in ducts or ventilation systems. Pneumatic actuators allow precise control of the valve’s position, providing efficient flow regulation in HVAC or industrial furnace systems.
Pneumatic Actuator Operated UPVC Butterfly Valve Constructed from UPVC for lightweight and corrosion-resistant properties. Pneumatically actuated for reliable control in chemical and water systems with low pressure.
Top-entry Triple-offset Butterfly Valve - Pneumatic Actuated Triple-offset design ensures a bubble-tight seal with minimal friction, often used in critical systems like oil and gas. Pneumatic actuation allows for remote, automated shut-off or flow regulation in high-performance applications.
Pneumatic Actuator Operated with Solenoid Valve Combines a pneumatic actuator with a solenoid valve for precise on/off control of the valve. Used in systems requiring automation and rapid response, such as process control and industrial automation.
