PPH Dual Block 3 Way Ball Valve
A PPH Dual Block 3 Way Ball Valve is a type of industrial valve made from Polypropylene Homopolymer (PPH) that is designed to control and direct the flow of fluids between three different pipeline ports. It uses a rotating ball with a drilled passage to allow, stop, or divert the flow of liquid within the piping system. The dual block design means the valve body is constructed in two separate blocks that are securely connected, allowing easy maintenance and replacement of internal parts.
The 3-way configuration enables the valve to divert flow from one inlet to two outlets or combine two inlets into one outlet, depending on the system design. Due to the excellent chemical resistance, corrosion resistance, and durability of PPH material, PPH Dual Block 3 Way Ball Valves are widely used in chemical processing, water treatment plants, and industrial fluid handling systems.
