What Affects Knife Gate Valves Value?

Brand & Manufacturer: Premium brands (Fisher, WKM, Cameron, Velan) command higher prices than generic or lesser-known manufacturers.
Size & Pressure Class: Larger valves and higher pressure ratings generally mean higher value. A 12" Class 600 valve is worth significantly more than a 2" Class 150.
Material: Exotic alloys (Inconel, Hastelloy, Monel, duplex stainless) are worth far more than standard carbon steel due to raw material costs.
Condition: New surplus (never installed) commands the highest prices. Functional used valves are next, followed by repairable units, and finally scrap-value items.
Certifications: Valves with current certifications (API, ASME, NACE) and full documentation are more valuable than uncertified units.
Market Demand: Current industry activity levels affect pricing. When oil & gas or construction is booming, valve prices rise.
