The Farab lever-operated lug butterfly valve model BVL150 is designed for flow control and shutoff 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 lug-style design allows installation between existing flanges, and the manual lever includes an angle lock for precise disc positioning. Operating temperature ranges from -10°C to 120°C, with pressure rating according to Class 150.
The Farab BVL150 butterfly valve features a lever mechanism with angle lock for precise control of disc opening and closing. The lug body provides high mechanical strength and facilitates installation in industrial pipelines. Precision-machined disc and seat surfaces minimize pressure drop and ensure smooth flow. The replaceable seat guarantees reliable sealing throughout the valve’s operational life. Each valve is hydrostatically and leakage tested according to API 598 standards to ensure safety, long-term durability, and accurate performance in industrial flow systems.

Before installing and using the Farab lever butterfly valve BVL150, system flow and pressure must be fully shut off and released. The valve must be aligned precisely with the pipeline axis to prevent excessive stress on the body and lever mechanism. Avoid applying lateral forces or hydraulic shocks during operation to protect internal components. Routine maintenance includes inspection of the disc, stem, sealing washers, and control lever to prevent leakage and premature wear. Following manufacturer instructions, using proper handling equipment, and monitoring valve performance ensures long service life and stable operation of the Farab lever butterfly valve while enhancing safety in water, wastewater, and industrial networks.
