High Performance Butterfly Valve

As an experienced China high-performance butterfly valve manufacturer, we utilize alloy steel for the valve body and disc, combined with a PTFE seat structure, ensuring stable performance in terms of sealing, corrosion resistance, and service life.

Product Details 

1. Valve Body and Disc Material Description

In terms of material selection, Zhongguan Valve's High Performance Butterfly Valve differs from ordinary butterfly valves:

Valve Body and Disc: Alloy Steel

High strength, good wear resistance

Suitable for high-pressure and frequent opening/closing conditions

More stable performance in petrochemical, power, and other applications

Valve Seat Material: PTFE

Reliable sealing performance

Corrosion resistant, low friction coefficient

Suitable for a variety of media environments

This material combination ensures reliable sealing while also considering long-term operational stability.

2. Structural Form and Performance Characteristics

High-performance butterfly valves are mainly used for industrial fluid regulation and shut-off, with an overall structural design that prioritizes engineering practicality:

• 90° rotary opening and closing structure, intuitive operation

• Optional metal hard seal or elastic seal forms

• Leakage rate meets international standards

• Low flow resistance, helping to reduce system energy consumption

Working temperature range approximately covers -40℃ to 600℃, adapting to various industrial environments.

The product complies with and meets:

GB

API

ANSI

Special sizes, special materials, and non-standard design services can be provided according to customer requirements.

5. Working Principle Description

This high-performance butterfly valve adopts a typical quarter-turn (90°) working method. The valve disc rotates within the valve body to control the opening and closing of the medium:

• When closed, the valve disc fits tightly against the PTFE valve seat, creating a reliable seal.

• It maintains a stable state even under certain pressure conditions.

• Easy to operate, with low installation and maintenance requirements.

Due to its compact structure and relatively light weight, installation can be completed by two people, making it suitable for rapid on-site construction. It is currently widely used in chemical plants, power plants, and heating pipeline systems.
