Apollo Valves offers the PVB 4A Series of pressure vacuum breakers featuring a unique modular check valve design, which is built around a self-contained “captured spring” check module that is easily removable for maintenance or replacement. The checks are also interchangeable in the same sizes between all three valves in the 4A Series family. The PVB 4A incorporates a standard freeze protection feature and stainless steel shutoff handles. Its all-bronze body resists corrosion for extended service life.
