A Side Entry Ball Valve is the most widely used ball valve design in industrial pipelines due to its simplified construction, fast availability, and ease of assembly. At Perfect Engineers, we manufacture robust, high-precision side entry valves that are ideal for oil, gas, water, chemical, and utility applications across industries.
If you need a cost-effective, full-featured valve that offers excellent sealing and is easy to inspect or repair, the Side Entry Ball Valve is the solution.
A Side Entry Ball Valve has its body split horizontally into two or three parts (two-piece or three-piece), allowing the ball and seats to be inserted from the side. This structure simplifies assembly, testing, and machining, making it one of the most economical and widely available valve types in the world.
These valves are suited for high-cycle, moderate- to high-pressure applications in above-ground piping systems.

All Perfect Engineers Side Entry Valves are:
Yes—but you will need to remove the valve from the pipeline for full servicing.
Yes. Our designs meet API 607 / ISO 10497 fire-safe certifications.
Side entry is better for general use and cost-saving. Top entry is ideal when inline maintenance is critical.
Yes. For high temperature, abrasive, or slurry applications, we offer metal-to-metal seated side entry valves.
