American rv50nl Rv Brass Pressure Relief Valve 1/2 in Mnpt X Fnpt 75 Psi Lead-free

Product Description

The American rv50nl is a lead-free brass pressure relief valve built for reliable overpressure protection in residential and light commercial plumbing systems. Part of the RV series from American Granby, this valve is designed to automatically release excess pressure before it can damage pipes, fittings, water heaters, or other system components. When system pressure rises above the factory-set limit, the valve opens and vents the excess, then reseats once normal pressure is restored. This automatic response helps protect equipment and reduce the risk of system failure or water damage.

The rv50nl features a 1/2 inch connection size with male NPT inlet and female NPT outlet, making it straightforward to install into standard threaded pipe assemblies. The 75 psi pressure rating suits a wide range of common plumbing and hydronic heating applications where controlled pressure relief is required by code or system design. The valve body is constructed from solid brass, a material well recognized in the trades for its durability, corrosion resistance, and long service life in wet environments.

The seat material is Buna-N, a synthetic rubber compound known for its resistance to water, oils, and moderate temperature ranges. This helps maintain a reliable seal during normal operation and allows the valve to reseat cleanly after a relief event. Lead-free construction means this valve meets current federal and state regulations for use in potable water systems, making it suitable for drinking water lines and hot water supply applications.

Plumbers and pipefitters will find the rv50nl easy to specify and install. It threads directly into standard 1/2 inch NPT fittings with no special tools or adapters required. It is a dependable, code-compliant choice for water heater installations, pressure booster systems, and closed-loop plumbing configurations.

• Lead-free brass construction meets federal and state potable water regulations
• 75 psi pressure rating provides reliable overpressure protection for residential and light commercial systems
• Buna-N seat material ensures a clean, durable seal through repeated relief cycles
