The 4A-200 series is a reduced pressure assembly. Production began in 2008. The 1/2"-2" is available in either a leaded bronze or lead free bronze body (LF). The check covers are a threaded access style. The check components are a modular glass filled PPO plastic and can be removed from the body for repair. Spring tension is contained when the check covers are removed. Check discs are silicone. The relief valve utilizes a bolted access cover. Spring tension is contained when the cover is removed. The 2 1/2"-8" size body is fabricated from stainless steel tubing and utilizes a single access cover contained by a quick connect coupling.
