Rising Stem Full Port, Expanded Parallel Slide Gate Valve, Double Disc, Bolted Bonnet, Integral Seal Rings - Metal to Metal. Mechanically loaded seating for low and high pressure sealing. Parallel slide dual loaded discs ensure superior shut off and allow by-pass/bleed fitment (double block and bleed requires soft seat inserts). Pressure/temperature charts available on request. Available in A105N, F22, F11, F5, 316, 304 etc. Quick acting - Uniflo style lever or key operated continuous boiler blow down valves (blow off) for installation in applications such as industrial, mining and mechanical services. Suitable for super-heated steam, H.T.H.W steam condensate and water. This design consists of two discs, kept in contact with parallel body seats, using the line pressure and sprung seating action to effect tight closure. Temperature changes in the line are accommodated by the expanding disc and do not affect the action of the valve. When being opened or closed, the discs slide across the seat faces, dislodging any foreign matter. The valve operating stem is outside screw rising through the handwheel. These valves are suitable for full bore steam use, where a low pressure drop across the valve is required. Also suitable for water, oil, gas, etc. Also available in Globe style, quick acting.
