• 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.
