Air Actuated Butterfly Valves for Industrial Automation

Automation Solutions for Global Pipelines

In modern industrial process control, system downtime is never an option. As an established manufacturer, we deliver engineered pneumatic control butterfly valves that guarantee rapid cycle times, bubble-tight sealing, and long-term reliability in severe working conditions. Our robust product line is designed to streamline automated pipeline operations across water treatment, chemical processing, and power generation sectors worldwide.

Compliant with Rigorous International Standards

Engineering compliance is at the core of our manufacturing process. Every China pneumatic actuated butterfly valve leaving our facility is designed, machined, and tested to meet or exceed global engineering protocols, facilitating seamless site integration and hassle-free inspection for international projects:

Design & Testing: API 609, ASME B16.34, API 598, EN 12266-1

Flange & Connections: ANSI B16.5 Class 150/300, DIN EN 1092, GOST 12815

Face-to-Face Dimensions: ISO 5752, API 609

Technical Capabilities & Configurable Specifications

We specialize in  air actuated butterfly valves configured to your exact technical datasheets. By combining precision valve bodies with high-torque rack-and-pinion actuators, we provide reliable flow regulation and critical emergency shut-off capabilities.

Flexible Configurations: Available in Wafer, Lug, and Double-Flanged body types from DN40 to DN3000+.

Premium Material Matrix: Body options include Ductile Iron, Cast Steel (WCB), and Stainless Steel (SS304/SS316). Discs are available with Al-Bronze or mirror-polished stainless steel coatings.

Sealing Systems: Resilient EPDM/PTFE seats for zero-leakage low-temperature services, or triple eccentric metal-to-metal seating for high-pressure, high-temperature thermal media.

Automation Accessories: Fully integrated with pneumatic double-acting or spring-return actuators, limit switch boxes, NAMUR solenoid valves, and smart positioners (4-20mA) for precise modulating control.

OEM Support & B2B Supply Chain Advantages

As a preferred pneumatic control butterfly valve supplier, we offer global distributors and EPC contractors direct factory pricing without compromising on material traceability. We understand the logistical demands of international trade, providing seaworthy, reinforced plywood packaging, complete material test reports (MTRs), and agile production lead times to match your project schedule.
