In most cases, the CPVC Dual Block 3-Way Ball Valve has two modes of operation: input and output. A three-way ball valve may be recommended in some systems when more than one medium is used. Instead of just two ports (entries), 3-way ball valves have three.
This multiport arrangement can divert fluid from the primary valve input in two different directions (instead of just one) via two independent valve outputs. The primary flow line is served by two separate and alternate inlets, which is another common application of CPVC Dual Block 3-Way Ball Valves.
Flow pattern, handle direction, and the range of 90-degree spin that the handle can make are all used to classify cpvc three-way ball valves. Because of how the valve ball is drilled and the pipe design, gas and liquid flow can be diverted, mixed, blocked, or completely stopped in one direction. By reducing the need for an additional tee and valve, multiport valves save space.
PETRONTHERMOPLAST has developed a TKD DUAL BLOCK® ball valve to introduce a high reference standard in thermosplastic valve design. TKD is a
True Union diverting and mixing ball valve that meets the most stringent needs required in industrial applications.
