The Mahab drain valve features a ductile iron GGG40 body with an electrostatic epoxy coating, ensuring resistance to corrosion, abrasion, and high pressure. It is manufactured in nominal diameters from 100 to 1600 millimeters, with a working pressure of up to 16 bar. The gate is made of stainless steel AISI 304 with EPDM or NBR rubber sealing, providing complete sealing under variable pressure conditions. The valve can be operated manually, via gearbox, or with electric actuators. The flanged design complies with EN 1092-2 standard, and the maximum operating temperature is 80°C.
The Mahab drain valve is designed for discharging water, sludge, or suspended solids from tanks, basins, and pipelines. All moving components are machined with ±0.3 mm precision to ensure smooth, vibration-free operation. Hydrostatic testing is performed at 1.5 times the nominal pressure, with allowable leakage below 0.1% of rated flow. The 600 mm model weighs approximately 120 kg. A 250-micron powder epoxy coating provides durability exceeding 20 years. This valve is widely used in water, wastewater, power plant, and treatment facility applications.

The Mahab drain valve is designed to control and quickly discharge water and wastewater in urban, industrial, and agricultural networks. These valves are made of corrosion-resistant cast iron or steel and can withstand working pressures up to 16 bar. Its simple and stable mechanism allows fast opening and closing of flow, preventing pressure buildup and hydraulic shocks in pipelines. Easy flanged installation according to PN16 ensures compatibility with existing lines. The Mahab drain valve in municipal sewage systems, industrial water transmission lines, and pressurized irrigation networks optimizes flow, reduces clogging risk, and extends network lifespan.
