How To Choose Right Gate Valve

Time: 16-July 2025 | Source: I-FLOW| Share

First Off, What’s a Gate Valve

A gate valve works like a sliding door inside your pipeline. When you open it, the “gate” lifts completely out of the way, allowing full flow. When it’s closed, it shuts off everything completely. No leaks. No halfway stuff. Just full-on or full-off.That’s why it’s great for isolation—not for flow control.

What to Look For

①What’s It Flowing
Water, gas, steam, or something sticky like slurry? Different gate valves are made for different stuff. Stainless steel or bronze for corrosive fluids. Cast iron for general water. Carbon steel for oil pipelines.
②Space: Tight or Roomy
If you’re installing in a tight space (like underground), go with a non-rising stem valve. If you want to see whether it’s open or closed, a rising stem is perfect.
③Is This Valve a Tough Guy
Will it face high pressure or heat? If so, make sure to check the PN or ANSI rating. A weak valve in a strong system is a recipe for disaster.
④Manual or Motorized
Small valves = turn by hand. Big or remote ones = use electric or pneumatic actuators. (Your wrists will thank you.)
⑤Don’t Forget the Certifications
Look for things like API, ASME, ISO, or CE. They’re your assurance that the valve’s built to perform.

Pro Tip

Never use a gate valve to throttle flow. Partially open gates can vibrate, wear out, or break down fast. Go for globe valves or control valves if you need to regulate flow.

Where Will You Use It

  • On a city water supply main
  • In a fire suppression system
  • On a marine ballast line
  • In an oil pipeline
  • At a power plant’s steam line

Why Globe Valve Is Unidirectional

The globe valve is one of the most common and versatile valves used in industrial and commercial piping systems. Known for its excellent throttling performance and reliable shut-off capability, it is designed with a unique flow path that makes it unidirectional — meaning fluid should only flow in one direction through the valve.
