The Farab metal seated gate valve with bronze rings model GVB16 is designed for complete flow shutoff in water, steam, and industrial medium-pressure pipelines. Its body is made of ductile iron GGG40 with a nominal pressure rating of PN16. The stainless steel gate is hard chrome plated, and sealing rings are made of corrosion-resistant bronze to ensure durability and precise sealing. Flanged ends comply with EN 1092-2 standards, and dimensions follow DIN 3202 specifications. It operates reliably from 0°C to 200°C with a maximum pressure of 16 bar, making it suitable for municipal water systems, heating networks, and process industries.
The Farab GVB16 gate valve features a straight-through flow path to minimize pressure drop and improve hydraulic efficiency. The stem is stainless steel, and sealing is achieved with heat-resistant graphite packing. Dual precision-machined bronze-seated rings ensure tight bidirectional sealing. A bolted bonnet provides easy access for maintenance and inspection. Each valve undergoes hydrostatic and leakage testing according to API 598 standards to guarantee operational safety, durability, and long service life.

When installing the Farab GVB16 metal-wedge gate valve, the pipeline must be fully depressurized to prevent sudden pressure-related hazards. PN16 flanges must be precisely aligned to avoid excessive stress on the ductile iron body. Proper gaskets and cross-pattern bolt tightening ensure safe and uniform sealing. During operation, impact forces on the handwheel or gearbox should be avoided to protect the stem and metal wedge. Regular inspection of the epoxy coating, leakage checks, smooth stem movement verification, and prevention of water hammer are essential safety measures. Adhering to approved pressure and temperature limits significantly enhances operational safety and the service life of the GVB16 valve.
