Series 60 Direct Spring Safety Valve
- Description
- Specifications
- Documentation
The Types 61 and 63B are direct spring operated safety valves suitable for medium set pressure gas, vapor, and liquid or gas thermal relief applications. Brass construction offers an economical valve for carbon dioxide, natural gas, and general gas or vapor services. The Type 61 is also suitable for cryogenic and chemically active applications.
Features & Benefits:
- Soft seat design as standard. Helps provide repeatable leak-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.
- Replaceable soft seat and seals. Easy seat and seal replacement, compared to refurbishment (no expensive, time consuming lapping of metal components) results in lower long-term maintenance costs.
- Meets ASME Section VIII requirements. Provides the user third-party verification of valve capacity and performance.
