The Farab metal seated O-ring gate valve model GVO16 is an industrial-grade valve engineered for on-off flow control in water, steam, and process pipelines. The body is made of ductile iron GGG40 with a nominal pressure rating of PN16, and the stainless steel gate is precision-machined to provide tight sealing. O-rings made of NBR or EPDM are used for bonnet and stem sealing, offering excellent resistance to temperature, pressure, and abrasion. Flanged ends conform to EN 1092-2, and installation dimensions follow DIN 3202. The valve operates within 0–200°C temperature and up to 16 bar pressure.
The Farab GVO16 gate valve features a straight-through flow path to minimize pressure drop and enhance hydraulic efficiency. The stainless steel stem ensures durability, and the bolted bonnet allows easy maintenance and inspection. Multiple O-ring sealing layers are employed in critical zones to prevent leakage under variable pressure conditions. Precision-machined metal seats provide bidirectional leak-tight performance. Each valve is hydrostatically and leakage tested in accordance with API 598 standards to ensure safety, longevity, and consistent performance under demanding operating conditions.

The price of the Farab GVO16 O-ring gate valve depends on factors such as the GGG40 ductile iron body, epoxy coating quality, nominal size from 2 to 24 inches, and PN16 pressure class. The type of EPDM O-rings, machining accuracy of the stem and wedge, and sealing performance significantly influence the final cost. Other key factors include actual weight, EN 1171 compliance, flange standards, and corrosion resistance. Maintenance cost, Farab’s manufacturing quality, long service life, and reliable performance in municipal water distribution systems further enhance the value of the GVO16 compared to similar models.
