Compact & Efficient
Butterfly Valve Solutions
Vcore butterfly valves provide efficient shut-off, flow isolation, and throttling service for HVAC, oil & gas, power generation, water treatment, and chemical processing. Compact structure, lightweight design, and quarter-turn operation for space-saving and reliable performance.
Core Features & Advantages
Compact & Lightweight
Lighter and takes up less space than globe or gate valves, making them ideal for large-diameter pipelines with reduced pipeline stress.
Quarter-Turn Operation
A simple 90° turn of the handle or actuator achieves quick shut-off and control, saving both time and energy.
Material Options
Available in cast iron, ductile iron, stainless steel, alloys, with soft or metal seats, to handle different media and environments.
High-Performance Design
Double-offset and triple-offset butterfly valves ensure zero leakage under high pressure and temperature.
Cost-Effective Solution
Compared with globe or ball valves, butterfly valves are more economical for large-diameter and low-pressure pipelines.
Customization & Delivery
Standard stock for fast delivery and custom-engineered butterfly valves for unique applications.

Frequently Asked Questions
What are Butterfly Valves commonly used for?
Butterfly valves are widely used in HVAC, water treatment, oil & gas, chemical processing, and marine industries, mainly for flow isolation, throttling, and shut-off service.
Concentric vs Double Offset vs Triple Offset?
Concentric: Standard design for low-pressure water and air systems.
Double Offset: High-performance design with reduced seat wear, suitable for higher pressure and temperature.
Triple Offset: Metal-seated design with excellent durability, ideal for critical applications like oil & gas.
Can Butterfly Valves replace Gate or Globe Valves?
Yes, in many cases butterfly valves are preferred for large-diameter pipelines, low-pressure systems, and where space-saving is crucial. However, for precise throttling, globe valves may be more suitable.
Are Butterfly Valves suitable for high-pressure service?
Yes, high-performance double-offset and triple-offset butterfly valves are engineered for high-pressure and high-temperature systems while maintaining excellent sealing performance.
What seat materials are available?
We offer EPDM, NBR, PTFE, and metal seats, depending on the application medium, pressure, and temperature requirements.
What body materials are available?
Cast iron, ductile iron, stainless steel 304/316, alloy steels, duplex — customized for your specific media and operating conditions.
