Surge-Suppression Air Valves are Combination Air Valves equipped with Regulated-Exhaust Devices (slow-closing devices) to limit secondary surges during column separation. The Val-Matic Surge-Suppression Air Valve provides full airflow into the pipeline during vacuum conditions to prevent a vapor pocket (vacuum) from forming.
  • Restrictor disc provides regulated exhaust to limit secondary surges during column separation

  • Ability to adjust air exhaust for greater surge suppression

  • Provides full vacuum flow port for maximum pipeline protection

  • Provides full vacuum protection for the pipeline

  • Provides controlled venting to suppress surges in pipeline
