RV-2

High-pressure, low-capacity relief protection for instrumentation systems

The Welker RV-2 Relief Valve is designed for high-pressure, low-capacity instrumentation applications requiring dependable overpressure protection. With a 100–2000 psig spring range, stainless steel construction, and optional threaded port for discharge piping, the RV-2 helps protect downstream equipment from pressure excursions while supporting hazardous gas applications that require venting to a safe area. Compact and corrosion-resistant, the RV-2 provides reliable relief valve performance for natural gas, sampling, and instrumentation systems.
