  • Overview: The Durbin 500# series provides the rugged durability of traditional process- control valves with the added benefits of modern technology and upgraded materials.  The valve is available in normally closed or normally open (fail-safe close or fail-safe open).

  • Materials of Construction: ​​The Durbin 500# series is constructed of stainless steel to protect against the damaging effects of corrosion .  All wetted components are constructed from corrosion-resistant materials (CRAs) or are engineered plastic materials.

  • Application: This valve series is ideal for applications where a high cycle life and repeated positive shutoff is required. This 2-way valve can be used to isolate one process fluid from another, to supply fluid or to provide a fast evacuation if normally open.   Whether it is high-temperature steam, or low- temperature cooling water, the Durbin 500# series can handle the application with the reliability, durability and repeatability that customers desire.
