Valve
Air Release & Vacuum Breaker Valve
VSCSA
VSCSA is a combination model of the VSC, a vacuum relief valve, and the SA, an air release valve.
Designed for use in marine, industrial, and plant piping systems, it provides reliable protection where pressure fluctuations occur.
This valve is installed at critical points in pipelines, penstocks, or tanks, and can relieve vacuum conditions in the piping system through the rapid influx of atmospheric air, automatically protecting the pipeline from contraction, deformation, or vacuum damage.
VSCSA is a combination of a spring-loaded type and a floating ball type, designed to handle under pressure with a minimum pressure of -200 mmW.C and a maximum setting of -10,000 mmW.C.
Introduction
Automatic Pressure Protection : You can safely manage positive and negative pressure conditions without manual operation.
Vacuum Protection : VSCSA automatically injects air under vacuum conditions to prevent pipeline collapse or deformation.
Easy Installation & Maintenance : Designed with simple flange connection, VSCSA ensures a long-service life through periodic cleaning and inspection.
Overflow Prevention : Internal floating ball prevents liquid leakage, maintaining system stability.
Robust Construction : VSCSA has manufactured with durable materials to withstand harsh operating environments.
Operational Reliability : VSCSA can provide consistent performance in various industrial and marine pipeline applications.
