Blakeborough® BV830 and BV831 Three-Way Valve

The Blakeborough BV830/831 series are popular top- and skirt-guided control valves available to customers in a variety of trims, capacities and options. The BV830 and BV831 valves are designed for either blending two different flows or dividing a flow into two proportional streams. The 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’s 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. BV831 valves are used for proportional control on flow-splitting applications. The valve has two outlets and a common inlet branch.
