The Taco 463-1 tank fitting is a combination tank drain and shutoff valve for pressure tanks in hydronic systems. It allows users to regulate pressure and manage air levels in their system. By maintaining an air cushion, the 463-1 ensures that fluctuations in water levels do not adversely affect your system. It also provides gravity flow prevention for the tank, which helps to curtail air reabsorption.
Single Handle Design
The 463-1 features a single handle for both the drain and shutoff functions. Managing pressure or emptying your pressure tank is as easy as twisting the handle to one side or the other.
