China Butterfly Valve Suppliers

A Butterfly Valve is a quarter-turn rotational Valve widely used in pipeline systems to control fluid flow, featuring a disc (or butterfly) mounted on a rotating shaft that opens or closes by turning 90 degrees. When fully open, the disc aligns with the flow direction, minimizing resistance; when closed, it seals against a seat to block flow. This compact design makes it ideal for large-diameter pipelines, offering space-saving and cost-effective flow control.

Constructed from materials like cast iron, carbon steel, stainless steel, or PVC, with seats made of rubber, PTFE, or metal, it suits diverse media—water, chemicals, gases, and slurries. Flange or wafer-style ends enable easy installation: flange connections bolt to pipeline flanges, while wafer types fit between flanges, often paired with a Flange Adaptor for compatibility with varying specs.

In system integration, it works synergistically with components: a Bellow Expansion Joint handles thermal displacements near the valve, while a Rubber Expansion Joint absorbs vibrations from pumps. A Flexible Metal Hose adds routing flexibility around the valve. For maintenance, a Dismantling Joint simplifies access, and a Duckbill Check Valve prevents backflow, enhancing safety.

Key advantages include quick operation, low pressure drop, and ease of maintenance. It excels in on/off and throttling applications, from municipal water systems to industrial processes. The quarter-turn action allows automation with actuators for remote control. By balancing efficiency, durability, and affordability, it ensures reliable flow regulation, making it indispensable in modern industrial, commercial, and infrastructure pipeline networks.

Butterfly Valve

‌Butterfly valve, also known as flap valve, is a simple regulating valve. ‌The main components of butterfly valve include valve body, valve stem and butterfly plate. Its working principle is to realize the function of opening, closing or regulating by rotating the butterfly plate around its own axis in the valve body. Butterfly valve is suitable for controlling the flow of various media, such as air, water, steam, corrosive media, mud, oil, liquid metal and radioactive media. It is mainly used in low-pressure pipeline systems to cut off and throttle.

Product Detail

The composition of butterfly valve includes main components such as valve body, butterfly plate, valve stem, sealing ring and operating mechanism, as well as accessories such as bearings, limit devices, position indicators and flanges. These components work together to ensure that the butterfly valve can work normally and safely.

The valve body is the main structure of the butterfly valve, which supports and fixes other components of the valve. The valve body is usually cylindrical, with a cylindrical boss on the upper and lower parts for mounting the valve stem.

The butterfly plate is the opening and closing part of the butterfly valve, which rotates around the valve shaft to control the flow of the medium.

The valve seat is a key component of the valve seal, which is usually made of elastic material or metal. The valve seat and the butterfly plate fit closely to form a sealing surface to prevent medium leakage.

WHAT A CLIENT SAY?

When the butterfly valve is fully open, the effective flow area of the valve seat channel is large and the fluid resistance is small, which helps to reduce the energy consumption of the pipeline system. The butterfly valve is opened and closed by the rotation of the butterfly plate. It is easy and quick to operate and can respond quickly to changes in the system. The butterfly valve can choose a variety of operation modes such as manual, electric, and pneumatic, which is convenient for customers to choose according to actual needs. Under low-pressure conditions, the butterfly valve can achieve good sealing performance and prevent medium leakage.

FAQ

Important things you should know

What are the differences between butterfly valves and gate valves?

Gate valves are the most common opening and closing valves, while butterfly valves refer to valves with a closing part as a disc, which mainly rotates around the valve shaft to achieve the opening and closing functions. It mainly plays the role of cutting off and throttling on the pipeline. The action mode, function and purpose are different.

What is the purpose of butterfly valve?

Butterfly valve can be used for the switch control of low-pressure pipeline media. Butterfly valve refers to a valve with a closing part as a disc, which rotates around the valve axis to achieve opening and closing.

What are the classification forms of butterfly valves according to their structure?

Center seal type, single eccentric seal type, double eccentric seal type and triple eccentric test butterfly valve.

How to connect the butterfly valve?

It can realize manual, turbine transmission, electric, pneumatic, hydraulic and electro-hydraulic linkage drive forms, and can realize remote control and automatic operation.
