SVL is a gate valve designed for unidirectional pressure, offering full bore flow with no flow resistance. A self-cleaning pocket prevents blockages during closure. The top of the valve is removable for easy inspection and maintenance, and on larger models, the O-ring seal against the steel seat can be replaced. SVL is operated manually with a push rod that can be locked in the open position. The valve can be connected using mechanical or electrofusion couplings, flanges, or butt welding. It is made from corrosion-resistant materials and is suitable for direct burial in the ground without additional protection. Applications: Surface water, wastewater, industrial water, as well as aquaculture and agriculture.Operation: Manual with push rod (lockable in open position).
