The Farab rubber seated gate valve model GSS25 is designed for full shutoff in water, wastewater, and non-corrosive fluid systems. The body is made of ductile iron GGG40 with a nominal pressure rating of PN25, and the gate is ductile iron coated with EPDM rubber for corrosion, wear, and high-temperature resistance. The sliding gate mechanism provides direct vertical movement with clear indication of open or closed position. Flanged ends comply with EN 1092-2, and dimensions follow DIN 3202 standards. Operating range is 0–80°C with a maximum pressure of 25 bar.
The Farab GSS25 gate valve features a straight-through flow path to minimize pressure drop and maximize system efficiency. The stem is stainless steel, and NBR O-rings provide reliable sealing to prevent leakage. A bolted bonnet allows easy access for maintenance and inspection. The flexible rubber gate prevents leakage and water hammer during closure. Each valve undergoes hydrostatic and leakage testing according to API 598 standards to ensure safe operation, long service life, and complete sealing under industrial conditions.

The Farab rubber wedge gate valve GSS25, with a corrosion-resistant cast iron or steel body and rubber-sealed internal disc, ensures leak-free operation and long service life in water, wastewater, and industrial networks. Proper installation, including axis alignment and use of PN16 or ANSI standard flanges, is essential for stable performance. Routine maintenance includes inspection of the disc, stem, and sealing washers, cleaning, and lubricating the internal mechanism to prevent premature wear and corrosion. Preventing hydraulic shock and excessive pressure, along with using suitable quality fluid, ensures long valve life and optimal system performance. Following these maintenance guidelines reduces operational costs and enhances network safety.
