Side Entry Ball Valve Overview

What Is a Side Entry Ball Valve

A side entry ball valve is a special valve. It lets you control liquids or gases by turning a handle. The ball sits inside the valve body. There is a hole in the ball’s center. When you turn the handle, the ball moves. If the hole matches the pipe, fluid flows through. If the solid part blocks the pipe, the flow stops.

This valve often has two or three pieces. The ball sits between these pieces. This makes it easy to take apart for cleaning or fixing. Many industries use this valve. It is reliable and simple to keep working.

TANGGONG VALVE has over 36 years of experience. They design and make these valves. The company uses strict checks and advanced tools. Every valve meets high standards. You can trust their side entry trunnion mounted ball valve and side entry floating ball valves. They work well in oil, gas, and chemical plants.

Key Features and Structure

You will see several important features in a side entry ball valve. The main parts are the body, ball, seats, stem, and actuator. Each part works together for strong shut-off and smooth use.

  • The body holds all parts together. Makers use carbon steel, stainless steel, alloy steel, or cast iron. These materials make the valve strong and long-lasting.

  • The ball sits in the middle. It turns to open or close the flow.

  • The seats press against the ball for a tight seal. This stops leaks, even with harsh chemicals.

  • The stem connects the ball to the handle or actuator. You use this part to turn the ball.

  • The actuator helps you use the valve fast and safely.

Here is a table showing common materials and how they work:

Tip: When picking a side entry ball valve, check the material and certifications. This helps you choose the right valve and keeps your system safe.

How Side Entry Ball Valves Work

Operating Mechanism

You use a side entry ball valve by turning the handle. The handle moves a part called the actuator. The ball inside spins. The hole in the ball matches the pipe. Fluid flows through the valve. If you turn the handle again, the solid part blocks the pipe. The flow stops right away. This makes the valve simple to use.

The main parts work together. The stem links the handle to the ball. The seats push against the ball. They make a tight seal. The body keeps all parts together. You get strong shut-off and smooth use. You can use manual levers, electric actuators, or pneumatic actuators. Each one lets you use the valve quickly and easily.

TANGGONG VALVE’s ball valves use strong materials. You find stainless steel, duplex steel, and Inconel. These materials fight rust and handle high pressure. The valves meet strict rules like API 6D and ISO 9001:2015. You get good performance in oil, gas, and chemical plants.

Tip: You can pick different ways to control your side entry ball valve. Manual levers are good for small systems. Electric or pneumatic actuators work well for bigger or automatic setups.

Flow Control Process

You control flow with a side entry ball valve by turning the handle. The ball moves inside. The hole opens or closes the path. You get full flow or shut-off. This design gives you easy flow control.

Standard ball valves can slow down flow. They do not give exact control for jobs needing careful flow changes. Control (V-Notch) ball valves are better for precise flow. You use side entry ball valves for quick shut-off and easy care. You do not use them for fine flow changes.

The side entry ball valve is known for its quarter-turn movement. You let fluid pass or block it fast. Top entry ball valves are easier to fix inside. Control (V-Notch) ball valves give you more exact flow control. You pick the right valve for your job.

TANGGONG VALVE’s ball valves give strong shut-off and low pressure drop. You get bubble-tight sealing. You can use these valves in pipelines, refineries, power plants, and water systems. The valves handle very hot and cold temperatures. You can trust their long life and good performance.

You see how a side entry ball valve works. You turn the handle. The ball spins. The valve opens or closes. You get strong shut-off and reliable use. TANGGONG VALVE’s ball valves give you quality and good performance for tough jobs.

Comparison with Other Ball Valves

Side Entry vs. Top Entry

You might wonder how side entry ball valves are different from top entry ball valves. Both types help control flow, but they are not the same. In a side entry ball valve, you put the ball in from the side. In a top entry ball valve, you put the ball in from the top. This changes how you fix and install each valve.

Here is a table that shows the main differences:

Feature

Top Entry Ball Valve

Side Entry Ball Valve

Design

Ball inserted from the top, compact design

Ball inserted from the side, requires complex disassembly

Maintenance
