OEM Double Eccentric Wafer High Performance Butterfly Valve Factories, Exporters
Product Description
High-performance wafer butterfly valve is an industrial valve for precise flow control.
Compact Construction
Wafer-type valve body construction minimizes space requirements and installation time.
Durable Materials
High-performance wafer butterfly valves are usually made of materials such as stainless steel, carbon steel or other corrosion-resistant alloys to ensure corrosion resistance and high temperature resistance.
Advanced Seat Design
The valve seat of high-performance butterfly valve is the biggest difference from ordinary double eccentric butterfly valve.
Bidirectional Sealing
High-performance butterfly valves provide bidirectional sealing, which can effectively seal in both flow directions.

Frequently Asked Questions (FAQ)
What is the primary function of a high-performance wafer butterfly valve?
It is an industrial valve engineered for precise flow control and tight shutoff across diverse liquid and gas piping systems.
What makes the seat design unique compared to standard double eccentric valves?
The seat structure is specially engineered—often incorporating welded stainless steel—to deliver enhanced sealing capability, longer service life, and reliable high-temperature resistance.
Does this butterfly valve support bidirectional sealing?
Yes, it provides reliable bidirectional sealing, ensuring tight shutoff in both media flow directions regardless of line pressure.
What size range and pressure ratings are available?
Valves are available from DN40 up to DN1800, with standard pressure ratings covering Class 125B, Class 150B, and Class 250B.
What actuation configurations are supported?
The top flange meets ISO 5211 mounting standards, enabling seamless operation via manual hand lever, gear box, electric actuator, or pneumatic actuator.
Why choose a wafer body style instead of flanged body styles?
The compact wafer design significantly minimizes face-to-face dimensions, reduces overall pipeline weight, and cuts installation labor and bolt-up time.
