China Butterfly Valve Supplier

1. Types of Butterfly Valve

a) Resilient-Seated Butterfly Valves

These valves commonly are concentric butterfly valves, and use a rubber seat, providing tight sealing and suitability for low-pressure applications. Common seat materials include EPDM, Viton, and NBR. They are capable of handling different temperatures and chemical mediums.

Resilient-seated butterfly valves are ideal valves for water distribution, HVAC systems, and general industrial applications due to their cost-effectiveness and reliability.

b) High-Performance Butterfly Valves

Also known as a type of double offset butterfly valves, the purpose of their design is to handle higher pressures and temperatures compared concentric butterfly valve. The double eccentric design reduces friction between the disc and seat during operation, increasing the valve’s using life and reliability. These valves are commonly used in chemical processing, oil and gas, and power generation industries.

c) Triple-Offset Butterfly Valves

Triple-offset butterfly valves offer superior performance in demanding applications. The triple-offset design ensures zero leakage and can withstand extreme high temperatures and pressures. Triple eccentric butterfly valves are used in petrochemical, and power generation sectors.

d) AWWA Butterfly Valves


AWWA Butterfly Valves are designed according to the standards set by the American Water Works Association (AWWA). AWWA valves are known for their durable construction. They can handle high flow rates and are available in sizes ranging from 3 inches to over 100 inches.

These valves are used in municipal water systems, water treatment plants, and industrial applications.

3) API 609 Butterfly Valves

API 609 Butterfly Valves comply with the American Petroleum Institute’s (API) standard for resilient-seated and metal-seated butterfly valves for oil and gas industry use. These valves are designed to provide reliable shutoff and control in high-pressure and high-temperature environments. API 609 butterfly valves’designs ensure bubble-tight sealing, low operating torque, and long service life. They are commonly used in petrochemical plants, refineries, and pipeline applications.

f) PTFE Fully Lined Butterfly Valves

PTFE Fully Lined Butterfly Valves are equipped with a full lining of PTFE (king of plastic), making them highly resistant to corrosive chemicals and extreme temperatures. These valves are ideal for applications in chemical processing, pharmaceuticals, and food industries. The PTFE lining provides great non-stick properties, reducing the risk of media buildup. These valves are designed to handle a wide range of chemical mediums.

2. Detailed Application of Butterfly Valve

a) Water Treatment

In water treatment plants, butterfly valves can play as a shut-off valve, because they has lighter weight and thinner FTF than globe valve, beside, they provide tight seal, ensuring no contamination, making them suitable for potable water applications, especially the concentric butterfly valves.

b) HVAC Systems

Butterfly valves control the flow of air and water to maintain desired temperatures level in HVAC systems. They are used in residential and commercial buildings for heating, and air conditioning applications.

c) Oil and Gas Industry

In the oil and gas industry, three offset butterfly valves manage the flow of crude oil, natural gas, and refined products. Their stable design can handle high pressures and temperatures, make them suitable for upstream, midstream, and downstream applications.

d) Chemical Processing

Butterfly valves can control precise fluid flow, as the valves’ materials and design can withstand aggressive chemicals and high temperatures, ensuring safe and reliable operation. ZFA high-performance butterfly valves are commonly used in these applications

e) Food Industry

Stainless steel butterfly valves or with rubber seat wras-approved seats ensure no contamination of food products.
