Taco’s new 3350 valve automatically feeds water to a hydronic system whenever pressure in the system drops below the pressure setting of the valve. The 3350 PRV reduces incoming pressure and automatically maintains system pressure to the valve’s adjustable set point. If the system pressure drops below the valve’s set point, it automatically will add water to the system. The 3350 is suitable for systems with fill-pressure requirements between 10-50 psi and features a fast-fill button with automatic reset. The valve automatically exits the fast-fill mode once the system is full and the desired set pressure is reached.
