Type 60/80 Series

Premium performance direct spring operated pressure relief valves that use special internals and soft seats to provide optimum, accurate performance

Featured :

• Soft seat design provides repeatable bubble-tight performance before and after each relief cycle.
• Leak-tight performance near set pressure allows higher operating pressure, resulting in increased process throughput and system optimization.
• Easily replaceable soft seat and seals eliminate expensive, time-consuming lapping of metal components, resulting in lower long-term maintenance costs.
• Externally adjustable blowdown on Types 81/83 allows precise adjustment of reseat pressure without affecting set pressure adjustment.
• Types 81/83 provide full lift at set pressure with no overpressure required.
