The Mahab metal gate valve with bituminous-coated disc features a cast iron body with internal and external epoxy coating, ensuring corrosion resistance up to 500 hours in salt spray testing. Its nominal diameter ranges from 50 to 1200 millimeters, with a maximum working pressure of 16 bar. The disc is made of wear-resistant steel with reinforced bitumen coating, allowing leak-free operation up to 1.1 times the nominal pressure. Flanged connections comply with EN 1092-2 standard, and the valve can handle fluid temperatures up to 80°C.
Mechanical performance of the Mahab metal gate valve with bituminous disc is guaranteed with ±0.5 mm manufacturing precision. A 300 mm valve weighs approximately 75 kg and can be installed in water, wastewater, and industrial pipelines. Hydrostatic testing is conducted at 24 bar, and leakage testing at 17.6 bar. The manual actuator is made of fatigue-resistant steel, with options for electric or pneumatic actuators. The disc’s hydrodynamic design optimizes fluid flow and minimizes pressure loss.

The Mahab metal wedge gate valve features a corrosion- and wear-resistant body and disc, offering longer service life and more stable performance than many foreign brands. Its metal-bitted coating increases resistance to chemicals and abrasive fluids, preventing leakage and premature wear. Precisely engineered flanges according to PN16 or ANSI standards ensure easy and secure installation in existing pipelines. Smooth and fast opening/closing mechanism, operating pressure tolerance up to 16 bar, and minimal flow pressure drop are other key advantages. Using Mahab gate valves enhances safety, reduces maintenance costs, and improves performance in water, wastewater, and industrial networks compared to similar alternatives.
