Main Feature
The two sealing faces of a slab gate valve are perpendicular to the pipeline axis, its closing member have double discs, valve equipped with a stretching mechanism. The gate valve is widely applicable for transmission pipeline system of natural gas,oil products and chemical engineering.
The valve obturator have two parts, the seal surface are parallel each other, and with wedge-shape joint surface. The obturator parts are separated from each other, it can ensure the sealing performance even when the temperature changes caused by deformation, and can avoid leaving the gate due to heat expansion choked open. At sealing surface using hard alloy material of corrosion and wearing resistance, so it can ensure the sealing performance and extend the service life. Fully enclosed structure design, keep the valve fine protection, can be used at all weather.
