About this item

The Cash-Acme 24799-0150 FWL-2 Safety Relief Valve is a compact, pressure-only bronze valve engineered to protect hot water systems from overpressure caused by thermal expansion. Designed for 3/4″ male inlet and 3/4″ female outlet connections, it mounts easily to tanks or tees—on either hot or cold-water lines.

Constructed with a durable bronze body and high-quality brass and stainless-steel internals, it features a silicone seat disc and stainless-steel spring. The valve reseats automatically after relieving pressure and offers preset factory settings of 75, 125, or 150 psi, with 150 psi available for this model. Approved to CSA (ANSI Z21.22/4.4) and ASME Section IV standards, its compact wear-resistant design ensures reliable and safe protection.
