Globe valves sit at the heart of many plants, yet they are often the first to get ignored when a schedule gets tight. A missed inspection can turn a simple leak into a costly shutdown. That’s why a clear, step‑by‑step checklist, much like the guidance on [choosing the right valve for high‑pressure applications](/globevalvegazette/how-to-choose-the-right-globe-valve-for-highpressure-applications-a-stepbystep-guide), is worth its weight in steel.

## Why a Checklist Matters

When I was a junior engineer, I once walked into a control room and found a valve that had been running dry for months. The seal was cracked, the body corroded, and the whole line had to be taken offline for a week. The lesson was simple: a little routine work saves a lot of emergency work. A checklist keeps the job consistent, makes training easier, gives you a paper trail for audits, and helps you follow best practices when [sizing globe valves for high‑pressure process systems](/globevalvegazette/stepbystep-guide-to-sizing-globe-valves-for-highpressure-process-systems).

## The Core Checklist

Below is the list I use on most of my projects. It works for stainless steel, carbon steel, and even exotic alloys. Feel free to adapt it to your own specs.

### 1. Visual Inspection (Monthly)

- **Look for leaks** – any drip around the bonnet, stem, or body is a red flag.
- **Check the packing** – the soft material around the stem should be clean and evenly compressed.
- **Inspect the handwheel or actuator** – make sure it turns smoothly without wobble.
- **Note corrosion or scaling** – rust spots, white deposits, or pitting need attention right away.

### 2. Stem and Packing Check (Quarterly)

- **Measure stem play** – the amount the stem can move without turning the valve should be within the manufacturer’s tolerance (usually a few millimeters).
- **Adjust packing** – tighten or replace the packing gland until you have a good seal but still can turn the handwheel without excessive force.
- **Lubricate the stem** – use a grease approved for the temperature and pressure of your system. A thin layer reduces wear and keeps the valve from seizing.

### 3. Seat and Disc Examination (Every 6 Months)

- **Remove the bonnet** – follow lock‑out/tag‑out procedures first.
- **Inspect the seat material** – look for cracks, erosion, or hard spots. Soft seats (like PTFE) wear faster than metal seats.
- **Check the disc** – it should sit flat on the seat when closed. Any tilt or uneven wear can cause leakage.
- **Clean both parts** – use a soft brush and a solvent that won’t attack the material. Avoid metal scrapers that can gouge the surface.

### 4. Bolts and Fasteners (Annually)

- **Torque all bolts** – use the valve maker’s torque chart. Over‑tightened bolts can stretch the body; under‑tightened bolts can let the bonnet shift.
- **Replace worn washers** – a thin washer can become a source of vibration and eventual leak.
- **Check for thread damage** – stripped threads mean you need a new bolt or a thread insert.

### 5. Pressure Test (Every 2 Years)

- **Hydrostatic test** – fill the valve with water, pressurize to 1.5 times the design pressure, and hold for 30 minutes. Look for pressure drop.
- **Air test (if water not possible)** – use a lower pressure and a leak detector spray. Never exceed the valve’s maximum rating with air.

### 6. Documentation (Ongoing)

- **Log every activity** – date, technician name, findings, and corrective actions. This makes future troubleshooting faster.
- **Update the valve’s “as‑found” condition** – if you replace a seat or packing, note the part numbers. It helps when you need a spare later.

## Tips for Making the Checklist Work

- **Assign a champion** – one person should own the schedule and remind the team when a task is due.
- **Use simple forms** – a printed sheet with checkboxes works better on the shop floor than a complex spreadsheet.
- **Train the crew** – walk them through each step at least once. A short video of you opening a valve and checking the stem can be a handy reference.
- **Keep spare parts handy** – the most common items are packing glands, seals, and a few standard bolts, and for high‑pressure systems you should also review [high‑pressure globe valve selection](/globevalvegazette/how-to-choose-the-right-globe-valve-for-highpressure-applications-a-stepbystep-guide). Having them in the maintenance closet cuts downtime dramatically.

## Common Pitfalls and How to Avoid Them

| Pitfall | Why It Happens | Fix |
|---|---|---|
| Skipping the seat check | Belief that seats last forever | Schedule the seat exam at least twice a year, even if the valve looks fine |
| Over‑tightening the packing gland | Trying to stop a small leak quickly | Follow the torque spec; a little leak is better than a seized stem |
| Using the wrong grease | Picking the first grease you see | Check the valve data sheet for temperature limits and chemical compatibility |
| Ignoring documentation | “It’s just a routine” | Treat the log as a legal record; auditors will thank you |

## A Quick Anecdote

Last winter I was called to a plant where a globe valve had frozen shut. The crew had tried to force the handwheel with a pipe wrench – not a good idea. When I finally got the valve open, the stem was bent and the packing shredded. A simple monthly visual check would have caught the early ice formation, and a proper winter‑grade grease would have prevented the freeze. The repair cost us three days of production and a new stem. Lesson learned: a few minutes of inspection beats a week of repair.

## Bottom Line

A globe valve is a simple device, but its reliability depends on disciplined care. By following the six‑point checklist – visual check, stem and packing, seat and disc, bolts, pressure test, and documentation – you can stretch the valve’s life well beyond the typical 10‑year horizon. Keep the list visible, train the team, and treat each step as a small investment in plant uptime.
