Metal Seated Butterfly Valve

Metal Seated Butterfly Valve is a high-performance industrial control valve designed for on-off and throttling duties in harsh working conditions.Featuring a metal-to-metal sealing structure,it integrates durability,corrosion resistance and high-temperature resistance,making it an ideal choice for demanding industrial pipelines.Different from soft-seated butterfly valves,its seat and disc are made of high-hardness alloy materials through precision grinding and surfacing processes,ensuring reliable sealing even under high pressure,high temperature and abrasive medium conditions.It is widely used in petroleum,chemical,power,metallurgy and other industries,suitable for various harsh media transportation and control.

The valve adopts a compact,lightweight design with a simple structure,facilitating installation and maintenance.Its disc is connected to the valve stem through a rigid structure,ensuring stable operation and accurate positioning during opening and closing.The metal sealing pair,made of wear-resistant and oxidation-resistant alloy,can withstand medium scouring and high-temperature erosion,maintaining good sealing performance for a long time.The manual or electric actuator(optional)is matched with a reasonable torque design,enabling labor-saving operation and precise control,with optional position feedback function for easy monitoring.

Technical specifications:Size range DN50-DN600;Pressure rating PN16-PN100,Class 150-600;Temperature range-29℃-450℃;End connection:flanged or welded,conforming to GB,ANSI,DIN standards;Applicable media:steam,crude oil,natural gas,high-temperature water,corrosive industrial fluids and abrasive media;Testing standards comply with API 598 and ISO 5208.

It boasts remarkable advantages:excellent high-temperature and high-pressure resistance,adapting to extreme industrial environments;metal seal ensures strong wear resistance and long service life;full-bore design minimizes flow resistance and pressure loss;simple structure reduces maintenance costs and failure rates;standard connection size allows direct replacement and retrofitting.Its applications cover thermal power plant steam systems,petrochemical medium pipelines,metallurgical process pipelines,natural gas transmission lines and other harsh industrial scenarios,providing reliable fluid control solutions.
