Description
The Caleffi 519600A Differential Bypass Valve helps keep proper pressure in hydronic heating and cooling systems by design. Made of high quality brass, this valve works well under 2-10 PSI pressure and connects using a 1″ NPT fitting, helping move water smoothly. When pressure between two points changes more than its set value, the valve automatically opens to keep water flowing smoothly through chillers and heat pumps. It does three essentials- stops damage to equipment, keeps systems working right, and uses less power by keeping pressure at safe levels.
