When a refinery, chemical plant, power plant, or manufacturing facility is decommissioned, the valve inventory often represents one of the most valuable asset categories. A single plant can contain anywhere from 200 to 5,000+ valves worth $100,000 to $2,000,000+ on the surplus market. This guide explains how to maximize the return on your valve inventory during decommissioning.

Why Valves Are Your Most Valuable Decommissioning Asset

Unlike pipe, structural steel, and vessels (which typically sell at scrap metal prices), valves retain significant value as functional equipment. A 6" Fisher control valve that cost $25,000 new can still command $8,000-$15,000 on the surplus market even after 15 years of service, provided it's in reasonable condition. The key factors that preserve valve value are:

• Brand recognition: Fisher, WKM, Cameron, Velan, and other tier-1 brands hold value
• Material specifications: Exotic alloys (Inconel, Monel, duplex SS) are always in demand
• Size and pressure class: Larger valves (8"+) and higher pressure classes (600#+) command premiums
• Standardization: Common sizes and configurations are easier to resell

Step-by-Step Liquidation Process

Phase 1: Inventory Assessment (Week 1-2)

Before removing any valves, create a comprehensive inventory. For each valve, document:

1. Manufacturer and model number (from nameplate)
2. Size, pressure class, and end connections (flanged, BW, SW)
3. Body and trim materials
4. Actuator type and model (if applicable)
5. Visual condition assessment
6. Photograph of nameplate and overall valve

Phase 2: Categorization and Valuation (Week 2-3)

Sort your inventory into value tiers:

Tier	Description	Typical Value	Examples
Tier 1 — Premium	High-value control valves, large bore, exotic materials	40-60% of new replacement	Fisher ET 6" 600# Alloy, Cameron 24" ball valve
Tier 2 — Standard	Common brands, standard materials, good condition	20-40% of new replacement	Fisher EZ 3" 150# WCC, WKM 370 8" gate valve
Tier 3 — Commodity	Generic brands, small sizes, or poor condition	10-20% of new replacement	Generic 2" 150# gate valve, corroded check valves
Tier 4 — Scrap	Damaged beyond repair, obsolete, or unknown brand	Scrap metal value only	Cracked bodies, missing internals, severely corroded

Phase 3: Sell to a Surplus Buyer (Week 3-4)

Case Study: Gulf Coast Refinery Decommissioning

A 50,000 BPD refinery in Texas recently decommissioned and contacted ValveBuyer.com with an inventory of 847 valves. The breakdown:

• 142 Fisher control valves (ET, EZ, V150 models) — valued at $380,000
• 215 WKM/Cameron gate and ball valves — valued at $290,000
• 180 Velan forged steel valves — valued at $95,000
• 310 miscellaneous (check valves, small gate valves, relief valves) — valued at $85,000

Total purchase price: $850,000 — compared to an estimated scrap metal value of only $45,000 if the valves had been cut up for recycling.

Common Mistakes to Avoid

1. Don't scrap high-value valves: Many demolition contractors cut up valves for scrap without realizing their equipment value. Always get a surplus quote first.
2. Don't remove nameplates: A valve without a nameplate loses 30-50% of its resale value because the buyer cannot verify specifications.
3. Don't store outdoors uncovered: Even a few months of weather exposure can significantly reduce value through corrosion.
4. Don't wait too long: Valve technology evolves. Older models depreciate as newer replacements become available.
