Rising Stem Full Port, Expanded Parallel Slide Gate Valve, Double Disc, Pressure Seal or Bolted Bonnet, Welded-in or Threaded Seat Rings. 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.

Suitable for super-heated steam, H.T.H.W steam condensate & 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 & 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 steam use, where a low pressure drop across the valve is required. Also suitable for water, oil, gas, etc. For superheated steam etc. consult chart.
