Brass Threaded Ball Valves
Union Brass Ball Valve
A union brass ball valve is a brass ball valve with a removable union connection on one end. Thanks to the union, the valve or the device it connects to can be easily installed and removed without dismantling the pipe line; for this reason it is frequently preferred in manifold, boiler, pump and heat metre connections.
Straight and angle type options adapt to different mounting directions. For heat metre (calorimeter) applications, types with temperature sensor (thermocouple) outlets are also available; nickel-plated body options are available. Red and blue lever or handwheel options allow go and return lines to be easily distinguished.
