The Blakeborough® 830 & 831 valves can be used on a wide variety of process applications, including air, water, steam, oil, gases, and chemical services. The BV830 has two inlets and a common outlet branch. It is used for proportional blending of two flows into one stream, on such applications as the control of process fluid temperature downstream of feedwater heaters.
The valve can also be used as a mixing valve to control the blending of two flow streams. The flow capacity is normally constant unless the valve trim is specifically designed with two different CVs. The BV831 valves are used for proportional control on flow splitting applications. The BV831 valve has two outlets and a common inlet branch.
