Built to keep pressure in check and performance on track, the Potter Roemer Model 4055-ACV Automatic Control Valve provides reliable downstream pressure control with flow regulation, pressure relief, and pump surge protection for demanding fire protection applications. The self-acting, pilot-operated valve reduces outlet pressure from an unregulated higher inlet pressure without pressure falloff. Featuring a ductile iron body and bonnet with stainless steel internal components, the valve is available with a globe body and grooved or flanged connections. A red RAL 3000 Fusion Epoxy Coating protects interior and exterior surfaces. UL 1739 listed in 1-1/2-inch through 10-inch sizes, it supports upstream pressures up to 300 psi with multiple downstream pressure settings.
