This valve is available for 2000, 3000 or 5000 psi working pressuresand can be supplied in sizes up to 4 1 /16” flanged or threaded.Main Design and Construction Features:• Integral cast steel body and one-piece bonnet.• Non-rising stem design.• Parallel expanding gate provides a tight mechanical metal seal between the seats, protecting bodyand operating components from flow in both open and closed positions.• PTFE ring in each seat ensures an initial seal between seats and gate in addition to the metal‐to‐metalseal generated by full expansion of the gate.• Valve does not rely on line pressure for sealing.• Roller thrust bearings minimize valve operating torque.• External bearing grease fitting allows easy lubrication of stem bearings.• Packing injection fitting allows the stem packing to be energized under pressure.• Body cavity is filled with grease to allow easier operation, corrosion resistance and longer life. Twosafety-capped grease fittings are provided on the body so that grease may be added at any time.• Continuous full bore / thru conduit flow at sealing surfaces minimizes pressure drop and turbulence.<strong>Stream</strong>-<strong>Flo</strong> Industries Ltd.
