PRESSURE/ TEMPERATURE WCB BODY The P316H style parallel slide is the same dimensions as the P316S except has pillar & bridge type top works. The P316H has spring energised discs. 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 tension spring to effect tight closure. Temperature changes in the line are accommodated by the energised discs 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 (OSY). 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. STANDARDS COMPLIANCE: Basic Design: API 600/BS EN 1984/S 5157/ANSI B16.34 Face to Face Dimension: ANSI B16.10 End to End Dimension: ANSI B16.10 Flanged Ends: ANSI 16.5 B.W.

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