Product Introduction：PFT gate valve with balance stem, rising stem design, to ensure the safety when working pressure from 2,000 to 20,000psi. Available bore sizes from 1-13/16" to 7-1/16", covering threaded end and flanged end connection. The trims of this gate valve can be used in various oilfield environments, including extreme sour gas.
·Metal-to-metal sealing between gate-to-seat;
·Bi-directional upstream sealing makes double bleed available;
·Full-bore, through-conduit gate-to-seat seal maximizes valve life by virtually eliminating turbulence and pressure drop;
·Lower stem balances pressure make body no volume difference to reduce operating torque when open and close the valve;
·Wave spring provides initial sealing preload to ensure the sealing property under low pressure.
