Type 200/400/500/700/800 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.
• Metal-to-metal seat design: Provides pilot valve performance in high temperature service.
• Bubble-tight seats near set pressure: Allows higher system operating pressure and, therefore, maximum process output; not as sensitive to vibrational and pulsating service; reduces product loss.
• Pop action available: No main valve throttling, which helps prevent freeze-ups in cryogenic or refrigerant type services.
