Pressure Relief Valves
Series 60/80
Premium performance direct spring operated pressure relief valves that use special internals and soft seats to provide optimum, accurate performance
Features
- 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.
Needle Valve
Series M50/H70
M50 and H70 valves are suited for severe service, instrument primary (root) type installations requiring rugged durability, reliability and safety. Both are intended to replace gate and globe valves found in traditional installations
Features
- Compact design requires minimum space for operation and installation; low weight increases connection strength and reduces gauge whip.
- In-line replaceable soft or metal seats eliminate the need for valve removal.
- Straight through bore allows rodding out.
- Non-rotating stem design eliminates packing wear and seat galling, extending valve life.
- API Firesafe 607 rated primary block provides assured reliability in severe service applications.
