Wafer Butterfly Valve

Farab lever-operated wafer butterfly valve model BVW16

The Farab lever-operated wafer butterfly valve model BVW16 is designed for regulating and isolating flow in water, air, and non-corrosive fluid systems. Its body is made of ductile iron GGG40 with a nominal pressure rating of PN16, and the disc is manufactured from aluminum bronze or stainless steel for superior wear and corrosion resistance. The seat is made of EPDM for tight shut-off, and the stainless steel shaft is supported by bronze bushings. The wafer-type body complies with EN 1092-2 and fits between various flange standards. The operating range covers -10°C to 120°C and pressures up to 16 bar.

The Farab BVW16 butterfly valve features a lever-operated mechanism with a locking position handle, allowing precise adjustment of the disc angle. The wafer body design reduces overall weight and simplifies installation in confined spaces. The smooth disc surface ensures minimal pressure loss during flow, while the replaceable seat provides reliable sealing under high pressure. Each valve is tested for hydrostatic pressure and leakage in accordance with API 598 standards to guarantee safe operation, long service life, and accurate performance in industrial flow systems.

Farab gear-operated wafer butterfly valve model BWG150

The Farab gear-operated wafer butterfly valve model BWG150 is designed for flow control and isolation in water, steam, and industrial fluid pipelines. The body is made of ductile iron GGG40 with a Class 150 pressure rating, and the disc is stainless steel or aluminum bronze for high corrosion and wear resistance. The seat is EPDM or NBR, and the steel shaft is supported by bronze bushings. The wafer-style body allows easy installation between standard flanges and reduces overall valve weight. Operating temperature ranges from -10°C to 120°C, with a pressure rating according to Class 150.

The Farab BWG150 butterfly valve features a gear-operated actuator that reduces the torque required to rotate the disc in high-pressure pipelines. The gearbox provides precise control of disc opening and closing, with a locking lever for position adjustment. The disc and seat surfaces are precision-machined to ensure minimal pressure drop. The replaceable seat guarantees tight sealing even under high Class 150 pressures. Each valve is hydrostatically and leakage tested according to API 598 standards to ensure safety, durability, and accurate performance in industrial applications.

Wafer butterfly valve

The wafer butterfly valve features a disc-shaped structure installed at the center of the pipe, allowing easy control of fluid flow. These valves are designed in a wafer style to fit between two pipe flanges, making their installation very simple and quick. One of the key advantages of the wafer butterfly valve is its ability to operate with minimal required force and to open and close rapidly, which enhances the efficiency of fluid transfer systems.
