Product Introduction：PFT expanding gate valve with non-rising design, to ensure the safety when working pressure from 2,000 to 5,000psi. Available bore sizes from 2-1/16" to 7-1/16", covering threaded end and flanged end connection. The trims of expanding gate valve can be used in various oilfield environments, including extreme sour gas.
Design Features
·Three types of sealing structure valves are available: double-side soft sealing structure, single-side soft sealing structure and metal-metal sealing structure.
·Split gate design provides an effective mechanical seal between gate and seat, regardless of pipeline pressure.
·Guide plate can effectively reduce the loss of lubricant in the valve chamber.
·The upper/lower thrust bearing space is isolated from the medium to effectively reduce the torque.
·Stem packing can be sealed by grease injecting under pressure.
·Non-rising stem design effectively reduces valve installing space.
