Product Overview

Bidirectional metal-sealed butterfly valve is a high-performance valve with excellent sealing performance, which is widely used in piping systems of petroleum, chemical, electric power, metallurgy, natural gas and other industries. The valve is suitable for water, oil, steam, gas and corrosive media, especially suitable for high temperature, high pressure and strong corrosive working conditions. Bidirectional metal seal design ensures that the valve can maintain reliable sealing in the case of bidirectional flow to prevent media leakage, and the sealing surface is not easy to wear. Product features include superior sealing performance, high temperature resistance, corrosion resistance, compact structure, rapid opening and closing, easy to operate, suitable for large flow and high pressure environment. The valve body adopts metal sealing structure, which ensures the stability under high temperature and high pressure working conditions, and can maintain efficient sealing even in harsh environments. Bidirectional metal-sealed butterfly valve is mainly used for cutting off, regulating and controlling fluids, which can ensure the stable operation of pipeline system, especially suitable for occasions requiring high sealing and bidirectional flow. Its excellent performance makes it an indispensable key valve equipment in industrial piping system.

Product Features

Bi-directional seals: Designed to handle fluids in both directions and are suitable for complex piping systems.
Ensures zero or minimal leakage and meets Class V or Class VI leakage standards.

Metal Seal Technology: High-grade stainless steel or alloy metal seats are used to withstand high temperatures and abrasive media.
Suitable for applications with corrosive chemicals, vapors or high pressure gases.

Triple Eccentric Design: The use of triple offset mechanism eliminates friction between the valve flap and seat during operation, thus reducing wear and prolonging valve life.
Provides tight closure while requiring only minimal drive torque.

Durable construction: Body and flap materials include carbon steel, stainless steel, duplex stainless steel or alloy steel to ensure superior mechanical strength.
Resistant to corrosion, thermal stress and mechanical damage.

Wide range of sizes and ratings: sizes from DN50 to DN1200 and pressure ratings up to PN40/ANSI 300.

Flexible actuator options: Compatible with manual, pneumatic, electric or hydraulic actuators that can be integrated with automation systems for precise remote control.

Low Maintenance Design: Frictionless operation minimizes sealing surface wear and reduces maintenance frequency and costs.

Product Advantages

High reliability: Bi-directional seals ensure stable performance even under changing flow conditions.
Capable of withstanding forward and reverse pressures without compromising seal integrity.

Cross-industry versatility: Suitable for a wide range of media including gases, vapors, oils, water and corrosive chemicals.
