OEM PTFE Full Lined Wafer Butterfly Valve Exporter, Exporters

Fully lined butterfly valve, with good anti-corrosion performance, from the structural point of view, there are two halves and one type on the market, usually lined with materials PTFE, and PFA, which can be used in the more corrosive media, with long service life.

Product Description

PTFE-lined butterfly valves are widely used in chemical, pharmaceutical, power generation, and other industries. These valves are specifically designed to control and regulate the flow of corrosive or abrasive fluids.
Corrosion & Thermal Resistance

The PTFE lining inside the valve offers excellent corrosion and high temperature resistance, making it ideal for a variety of industrial applications.

Wafer Style Compact Design

The wafer style design of these butterfly valves makes them lightweight and easy to install between flanges, facilitating installation and saving valuable space.

Low Maintenance & High Flow

Known for their durability and low maintenance requirements. The valve's disc design reduces turbulence and enables high flow rates, making it a cost-effective solution.

In summary, PTFE lined wafer butterfly valves provide an effective method of regulating corrosive and abrasive fluids. Their reliability, durability, and efficiency make them ideal for a wide variety of industries.

Frequently Asked Questions

◆ What are the primary applications of PTFE-lined butterfly valves?

They are predominantly utilized in chemical, pharmaceutical, and power generation industries where flow isolation and regulation of corrosive, hazardous, or abrasive fluids are essential.

◆ What are the advantages of a wafer style butterfly valve?

Wafer-style butterfly valves feature an ultra-compact, lightweight body designed to fit neatly between pipe flanges. This reduces installation time, structural support requirements, and spatial footprint.

◆ How does PTFE lining enhance valve performance?

PTFE offers near-universal chemical inertness, high temperature capability, and a low friction coefficient. It isolates internal metal surfaces from aggressive media, extending service life and reducing maintenance costs.

◆ Which actuation methods are available for these valves?

They can be configured with manual hand levers, worm gear boxes, pneumatic actuators, or electric actuators adhering to the standardized ISO 5211 top mounting flange.

◆ What size ranges and pressure ratings are supported?

Available sizes range from DN40 to DN600, with standard pressure ratings covering PN6, PN10, PN16, PN25, Class 150, and JIS 5K/10K/16K flange configurations.
