Side Entry Ball Valves Collection

A side entry ball valve is a simple turn-on/off device with a ball at the center of its structure. This ball controls the flow of the liquid or any other medium inside the pipe. The body of a side entry valve is divided into 2-3 parts. The main components of the valve are the stem, seat rings, and ball. These main components are held together by several smaller parts, such as bolts. The side entry ball valve is often confused with the top entry ball valve; however, these two are very different. 

A side ball valve generally has a 2-3 piece assembly and is very easy to assemble compared to other valves such as top entry ball valves. These valves also have a longer lead time because of the casting operation at manufacturing them.

We are the best top entry ball valve manufacturers and we ensure to provide only high-quality valves.

Side ball valve structure

These ball valves are generally made up of forged steel bodies. Let us have a look at their structure now:

Side Entry Ball Valve Sourcing Guide

How Does a Side Entry Ball Valve Work?

Side Entry Ball Valve

Source: Dombor

Side entry ball valves have a spherical closing unit for on/off flow control. This unit has a bore through its centre. When in an open position, the valve aligns the bore to the pipeline direction and fluid flows through it. When you rotate the valve for an angle of 90o, the bore is closed, which closes the valve and stops fluid flow.


 How to Choose a Side Entry Ball Valve When Sourcing

When purchasing from a side entry ball valve manufacturer, here are some specifications you should consider.

  • Ball type: Trunnion or floating mounted design 
  • Bore type: Reduced or full bore
  • Seating type: Metal or soft seated
  • The operating mechanism: Gear, lever, or actuated
  • Sealant injection system requirements. 
  • Locking device
  • Antistatic device
  • Size and pressure rating 
  • Materials of the valve body and other parts, such as trunnion and seals
  • Valve orientation 
  • Painting details if necessary
