API 6D Parallel Expanding Gate Valve
Categories：API 6D Parallel Expanding Gate Valve
FYV manufactures the most dependable Parallel Expanding Gate Valves in the industry. The full port bi-directional flow capability minimizes pressure drop and turbulence. The valve obturator have two parts, the seal surface are parallel 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.
API 6D Expanding gate valves are typically suitable for wet, sour, liquid or gaseous hydrocarbon services. It is widely applicable for transmission pipeline system of natural gas 、oil products and chemical engineering.
