Understanding the Basics

To install, it’s important to understand “perplexity” and “burstiness,” which impact writing quality. These factors play a significant role in determining the effectiveness of the written content.

Perplexity gauges the intricacy of the text, while burstiness examines the variety in sentence structures. Human-generated content often exhibits greater burstiness, incorporating both intricate and concise sentences. In contrast, AI-generated content tends to be more uniform. We’ll strive to incorporate these textual elements to convey the following information effectively.

Installation Guidelines

Here’s a way to get the test valves flowing smoothly—proper from the start! These 3 pipe layout regulations are your non-negotiable roadmap to a continuing test valve installation, making the highest quality overall performance and operation of check valves:

Pipe Design Rules

1. Install Check Valves in Non-turbulent (Laminar) Conditions
   1. Designing pipes connected to check valves with straight, smooth, and non-turbulent (laminar) flow is imperative for optimal performance.
   2. Generally, you should have five times the standard pipe size (NPS) of straight pipe. However, You can put some check valves on pipes that aren’t perfectly straight.
2. Properly Calculate Valve Size
   1. Sizing check valves differs from sizing on-off and control valves. It’s essential to determine the appropriate valve size for each application.
   2. Avoid assuming that nominal valve and pipe sizes match, and perform sizing calculations for minimum, maximum, and normal flow conditions.
3. Install in the Proper Orientation
   1. The orientation of valve installation plays a significant role in its smooth operation. The valves don’t have to deal with gravity in horizontal lines, so they work better most of the time.
   2. Many valves can be used in lines across the room, but quiet axial flow check valves work best in lines that go up and down.

Installation Guides

Improper installation can lead to check valve failure and potential damage to the entire system. Installation methods may vary depending on the type of check valve. However, here are some best practices for flapper-type swing check valves:

• Inspect the valve to ensure that you have removed all transport and storage materials.
• Verify that the flapper operates freely on the seating surface and back.
• Ensure no obstructions at the valve’s edges might hinder proper sealing.
• Install the valve with the direction of the flow arrow and provide a 3-diameter straight pipe upstream.
• In vertical installations, ensure the flow direction opposes gravity (up-flow).
• Horizontal installations require a cover on the top of the valve.
• Always inspect and test-run the valve post-installation to prevent premature swing check valve failure.
• The swing check valve should be free of any packaging or shipping debris when purchased from reliable swing check valve manufacturers. If you use this method, the valve might work better every time.

Professional Installation

For installing industrial check valves, we strongly recommend enlisting the expertise of qualified and licensed professionals. These people have put in valves before, so they know to ensure they are installed correctly. It’s less possible that something will go wrong now.

Check Valve Seat Replacement Guide:

Valve seats are critical components of check valves, responsible for sealing against the closure element to maintain proper shutoff. These seats may require replacement due to the following:

• Wear and tear from friction or aging.
• Misalignment during installation with the check valve closure element.
• Pieces and pieces on the closing element’s surface or inside the valve can damage the seat.

Neglecting the replacement of damaged valve seats can result in leakages, backflow, and non-return valve failure. Follow these steps for a successful replacement:

• Drain the fluid from the pipeline.
• Loosen connecting belts and nuts and, if necessary, remove the valve from the pipeline.
• Remove the cover bolts and the valve cover.
• Take out the gasket and closure element.
• Uncouple and replace the damaged seat with a new one.
• Reassemble the valve with the new seat part.
• Return the valve to its operational state.
• By testing it, please verify that the valve seat no longer has a problem.

Check Valve Handle Replacement Guide:

While most check valves operate automatically and do not require handles, stems, or actuators, stop-check valves are the exception. It is possible to control and isolate fluid flow with these valves externally. Handles on stop check valves may need replacement from time to time. Follow these steps:

• Drain the fluid from the pipeline.
• Turn the valve to the closed position.
• Loosen connecting bolts and nuts.
• Uncouple and remove the valve handle.
• Replace the old valve handle with a new one.
• Reassemble the valve with the new handle part.
• Return the valve to its operational state.
• If the problem persists, test the valve handle.

The Most Common Causes and Symptoms of Check Valve Failure

A failing check valve can be a disaster when you’re operating any liquid handling equipment. By understanding why valves fail and how to detect the early warning signs of valve failure, you’ll be able to prevent them from failing in the first place and avoid costly downtime and repair.

Causes of valve failure

If you’re running a system that transports any type of fluid through piping, it’s likely that you rely on check valves as a system safeguard. For guidance on selecting the right valve for your system, check out our blog post on 5 Great Ways to Think About Choosing a Valve. Check valves allow fluid to flow in one direction, preventing backward flow by opening and closing in response to hydraulic pressure. Here are the top reasons for this type of valve failure:

1. Incorrect installation and assembly
By incorrectly installing or assembling valves, you are setting yourself up for problems further down the line. It is crucial to select the right check valve, sized for the application, and install it correctly. By installing the correct check valve, you’ll prevent premature valve failure. Our tip? Remember to take note of flow capacity and the positioning and orientation of the valve during installation.

2. Insufficient maintenance
Regular maintenance is a sure-fire way to safeguard against failing valves. Look out for any signs of wear and check the pipeline for debris, which can get stuck in the valve and cause damage to the internal mechanisms. If you see any signs of deterioration, replace your valves as soon as possible.

3. Reverse flow
Reverse flow occurs when water flows upstream of the check valve. This can be extremely costly and dangerous when it occurs at the pump discharge, causing the pump to spin backwards, which damages the pump over time. Prevent this problem by ensuring your valve is working correctly (fast-closing and tight shutoff).

4. High temperatures
You should be aware that any application which runs at high temperatures can cause valves to fail early. Make sure that you keep an eye on your check valves and replace them if you see any sign of wear and tear.

Symptoms of valve failure

Valves emit warning symptoms when something isn’t right. For example, check valves that are starting to fail will vibrate or make a noise indicating that the valve has broken.

A strange noise can also be a sign of ‘water hammer’ which is a high-pressure surge that occurs when the fluid comes to a stop or changes direction, often causing the disc to slam into the valve. Valves can also start to ‘chatter’ with repeated opening or closing due to oversizing. If a valve is sticking or leaking, this could be a sign of wear and tear, or that debris or other contaminants are in the pipeline.
