150bl Straight Type Storm Valve
Our 150lb straight type storm valve features an advanced bellows seal design that eliminates stem leakage, making it the ideal choice for applications where fugitive emissions must be prevented. The straight-through body configuration provides a more direct flow path compared to conventional globe valves, reducing pressure drop and improving flow efficiency while maintaining precise throttling control.
Overview
Application : 150lb straight type storm valves are specified for piping systems where external leakage cannot be tolerated. Their bellows-sealed design makes them essential for handling hazardous, toxic, expensive, or environmentally sensitive media that must not escape to atmosphere.
