🔍 Quick Overview
Brass valves are among the most widely used flow control components in plumbing and industrial systems—but how many types of brass valves are there, and which one is right for your application? At Vcore Valve, we regularly help buyers navigate this question. This guide explains the main types of brass valves, their structures, applications, advantages, and limitations, helping you choose confidently for water, gas, HVAC, and light industrial use.
🎬 Opening Scenario: A Common Buyer Question
“We need brass valves—but which type?”
“Ball, gate, globe, check… how different can they really be?”
In practice, choosing the wrong brass valve often leads to leakage, pressure loss, or premature wear. Let’s simplify the confusion.
⚠️ User Pain Points
1. Too Many Brass Valve Types, Too Little Clarity
Buyers often struggle to distinguish between brass ball valves, brass gate valves, and brass globe valves, especially when suppliers oversimplify specifications.
2. Misuse Causes Early Failure
Using the wrong brass valve type for throttling, isolation, or backflow prevention can shorten service life dramatically.
3. Material Assumptions
Not all brass alloys perform equally—incorrect alloy choice may lead to dezincification or corrosion.
✅ Solutions & Expert Recommendations
1. Understand Functional Categories
Each brass valve type is designed for a specific flow-control function, not interchangeability.
2. Match Valve Type to Media and Pressure
Water, gas, and HVAC systems impose different demands on brass valves.
3. Choose Certified Manufacturing
At Vcore Valve, our brass valves are produced with controlled alloy composition, CNC machining, and pressure testing.
