2-Inch Electric Ball Valve Selection Guide

The 2-inch electric ball valve is a common size used in water treatment, automation, HVAC, irrigation, and other systems. This valve size serves as the ideal bridge between miniature valves and industrial-grade valves.

However, even among 2-inch electric ball valves, requirements for actuator torque, working pressure, switching time, and materials vary significantly across different operating conditions.

Selecting the correct 2-inch electric ball valve remains the biggest challenge for many valve procurement managers and engineers.

This article analyzes two actuator solutions for Jinfeng Valve's 2-inch ball valves to help you identify the most suitable option.

Why is the 2" ball valve the most commonly used industrial size?

1. High flow capacity, suitable for various applications including water treatment, agricultural irrigation, and chemical media.

2. Flexible installation options including internal threads, external threads, and flange connections

3. Compatible with a wide range of actuator models featuring moderate torque requirements

In low-pressure applications, low-torque actuators suffice, while large-scale water treatment plants and industrial-grade pipeline systems necessitate higher-torque actuators.

Small-bore valves: 1/4“, 1/2”, 3/4“, 1”

Product Features:

It requires minimal torque for operation, typically 1.5-2 Nm.

Lowest cost

Medium-Sized Valves:1.5",2"

Product Features:

Compatible with both miniature high-torque actuators and industrial-grade actuators.

Large-Bore Valves: 2.5“, 3”, 4"

Product Features:

High Flow Capacity

Requires a high-torque actuator for operation

Summary: How to Select the Right 2-Inch Electric Ball Valve

Three Core Questions:

1. Is the pipeline operating pressure high?

High pressure → Choose industrial-grade valves

Medium/low pressure → Choose compact valves

2. Budget and operating conditions

High budget → Industrial-grade

Low budget → Miniature models

3. Other size considerations

Small diameters (1/4“, 1/2”, 3/4“, 1”) → Satellite actuators

Large diameters (2.5“, 3”, 4") → Industrial-grade actuators
