• Overview: The Durbin Piston Top Series (PSI) provides the rugged durability of traditional process-control valves with the added benefits of modern technology and upgraded materials. This version of the PSI family is designed to work within your existing manifold system as a direct, drop-in replacement.

• Materials of Construction: The Durbin PSI 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.  Multiple engineered plastic materials are used throughout the dynamic components as guide bushings to protect against the galling and wear typically found in this type of valve.
  
  
• Application: This valve series can be used as a supply valve, a drain valve, a redundant valve,  or anywhere simple on/off functionality is required.  This series requires less pilot air than traditional diaphragm style valves while delivering consistent and reliable performance.  Whether it is high-temperature steam, low-temperature cooling water, or simply a vent application, the Durbin PSI series can handle every application with the reliability, durability and repeatability that customers demand.
