High-capacity gas instrumentation relief for safer overpressure protection
The Welker RV-110 Series Relief Valve is designed to protect high-capacity gas instrumentation from overpressure events. Built with ASME design standards in mind, the RV-110 provides 10% overpressure relief capacity and stainless steel construction for reliable safety performance. Available for non-hazardous gas applications where venting to atmosphere is allowed or hazardous gas applications requiring discharge to a safe area, the RV-110 helps prevent pressure from exceeding maximum allowable working pressure and protects critical pneumatic instrumentation.
