Industrial Butterfly Valves: Reliable Flow Control for Diverse Industrial Applications

What is a Butterfly Valve?

A butterfly valve is a versatile, compact quarter-turn valve designed for on/off isolation and throttling flow control across industrial, municipal, and commercial pipeline systems. As a space-saving alternative to ball valves and gate valves, our butterfly valves deliver reliable performance with low operating torque, minimal pressure loss, and easy installation. We offer a full range of configurations, from economical general-purpose water butterfly valve and air butterfly valve (butterfly damper) solutions, to high performance butterfly valve models for extreme working conditions, and advanced triple offset butterfly valve for bubble-tight shut-off in critical services.

Core Butterfly Valve Configurations & Selection Guide

We provide a complete portfolio of butterfly valves to match every piping layout and application requirement:

Wafer Butterfly Valve

The wafer butterfly valve is our most economical and compact solution, designed to fit between two pipeline flanges with bolt-through installation. Ideal for general water supply, HVAC, and low-pressure industrial systems, it offers lightweight construction, easy maintenance, and space-saving design for tight piping layouts.

Lug Butterfly Valve

The lug butterfly valve features threaded lug inserts on both sides of the valve body, enabling single-side flange installation and disassembly without disrupting the entire pipeline system. It is the preferred choice for maintenance-intensive applications, water treatment plants, and petrochemical systems, offering superior structural stability and reliable isolation performance.

Actuated Butterfly Valve

For automated flow control, our actuated butterfly valve can be equipped with electric, pneumatic, hydraulic, or worm gear drive options, supporting remote control, proportional regulation, and emergency shut-off functions. From simple manual butterfly valve operation to fully automated PLC-integrated systems, we customize actuation solutions to match your operational requirements.

Triple Offset Butterfly Valve

Our flagship AeroSeal HP triple offset butterfly valve is engineered for critical isolation services, featuring a unique triple offset design that eliminates seat rubbing during operation, ensuring zero-leakage bubble-tight shut-off even in extreme temperatures and high-pressure environments. It is the industry standard for oil & gas, power generation, and chemical processing applications.

Key Features & Benefits of Our Butterfly Valves

• Wide Operating Range: Accommodates pressures from 0.25MPa to 76.0MPa, temperatures from -196°C to 816°C, and nominal diameters from DN15 to DN4000, covering all mainstream industrial application requirements.
• Superior Sealing Performance: Multiple lining and seal material options ensure zero leakage, compatible with water, oil, gas, corrosive media, and abrasive fluids.
• Compact & Lightweight Design: 70% smaller and lighter than equivalent gate valves, reducing installation space, pipeline load, and overall project costs.
• Low Operating Torque: Quarter-turn operation enables quick open/close with minimal force, reducing actuation power requirements and extending service life.
• Compliant with Global Standards: All valves are manufactured in accordance with GB, DIN, API, ANSI, JIS, and BS international standards, compatible with global pipeline systems.
• Customizable Solutions: Full customization of materials, drive types, pressure ratings, and connection standards to match your specific project requirements.
