Hard seal butterfly valve

Product Overview

The Bi-Directional Metal Sealed Butterfly Valve is a high-performance valve designed for reliable flow control in both flow directions. Unlike conventional unidirectional butterfly valves, this valve utilizes a robust metal sealing structure to ensure effective sealing under bi-directional flow conditions. It is ideal for demanding industrial applications that require high-pressure, high-temperature, and severe environmental resistance.

The valve’s advanced design, including a precision-engineered metal seal ring and eccentric sealing mechanism, ensures durability and long service life, even under challenging working conditions.

Key Features

Bi-Directional Sealing:Designed to handle flow from both directions, making it versatile for complex pipeline systems.
Ensures zero or minimal leakage in compliance with Class V or Class VI leakage standards.

Metal Sealing Technology:Utilizes a high-grade stainless steel or alloy metal seat that withstands high temperatures and abrasive media.
Suitable for applications with aggressive chemicals, steam, or high-pressure gas.

Triple Eccentric Design:Features a triple offset mechanism that eliminates friction between the disc and seat during operation, reducing wear and extending valve life.
Provides a tight shutoff while requiring minimal torque for actuation.

Durable Construction:Body and disc materials include carbon steel, stainless steel, duplex stainless steel, or alloy steel, ensuring superior mechanical strength.
Resistant to corrosion, thermal stress, and mechanical damage.

Wide Range of Sizes and Ratings:Available in sizes ranging from DN50 to DN1200 and pressure ratings up to PN40/ANSI 300.

Flexible Actuation Options:Compatible with manual, pneumatic, electric, or hydraulic actuators, enabling integration with automation systems for remote and precise control.

Low Maintenance Design:Frictionless operation minimizes wear on sealing surfaces, reducing maintenance frequency and costs.

Advantages

High Reliability:Bi-directional sealing ensures consistent performance even under variable flow conditions.
Capable of handling both forward and reverse pressure without compromising sealing integrity.

Versatility Across Industries:Adapts to various media, including gas, steam, oil, water, and aggressive chemicals.

Cost-Effective Solution:Long service life and minimal maintenance requirements reduce total ownership costs.

Environmentally Friendly:Metal seal eliminates the need for soft seals, reducing waste and ensuring compliance with strict environmental regulations.

Summarize

The Bi-Directional Metal Sealed Butterfly Valve is engineered for exceptional performance in the most demanding industrial environments. Its ability to provide tight shutoff in both flow directions, combined with its robust construction and versatility, makes it an indispensable solution for industries requiring reliable flow control. Whether operating under extreme temperatures, high pressures, or corrosive conditions, this valve ensures optimal safety, efficiency, and cost-effectiveness.
