Guocheng Valve Group Co.,LTD. is one of the leading China API 6D SLAB & EXPANDING GATE VALVE manufacturers, welcome to wholesale cheap API 6D SLAB & EXPANDING GATE VALVE from our factory.
API 6D THROUGH CONDUIT SLAB & PARALLEL EXPANDING GATE VALVE
OVIKO produces a full line of API-6D Through Conduit Gate valves in both slab and expanding gate design. We offer a full range of materials and classes from standard to high and low temperature service based on customer requirements for performance in critical and primary isolation, bubble tight shutoff in liquid pipeline applications.
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 in good protection, can be used at all weather.
