Dual-Plate Check Valves: Butt Weld End Type

Description

Dual-plate check valves with butt weld end connections are designed to prevent reverse flow in high-pressure pipelines. These valves feature a compact, lightweight design with dual plates that open and close efficiently, reducing pressure drop and water hammer effects. They are ideal for critical applications in oil & gas, petrochemical, power, water treatment, and industrial sectors.
