RVM-TG is a gate valve designed for bidirectional liquid pressure, featuring a full bore with no flow resistance.Dual lip seals and O-rings ensure a tight seal in both directions. The top section of the valve is removable for inspection and maintenance, and the valve is manually operated by default using a handwheelwith low torque for smooth and easy operation.RVM-TG features a non-rising stem and can be connected using a socket, electrofusion socket, flange, or by butt welding. The valve is suitable for direct installation in the ground or in manholes, even without additional protection.The materials used are corrosion-resistant, ensuring long service life even in demanding environments.Applications: Surface water, process water, clean water, and aquaculture.Actuation options: Manual, electric, pneumatic, or hydraulic.A special flange for wall and manhole installation is available as an option.
