Name: DIN B Cast Iron Bellows Seal Globe Valve (Cut-Off Valve)
SKU: 1000959

Description

The DIN standard cast iron globe valve (cut-off valve) is engineered for high-performance isolation in industrial piping systems. It features a robust double seal design combining a metal bellows and backup packing to ensure zero stem leakage. This design is critical for handling hazardous or expensive media, preventing fluid loss, and ensuring plant safety. The valve is constructed from high-grade GG25 cast iron with advanced surface treatments for durability.
