High Pressure API 602 Forged Steel Valve Hardfaced F55 F51 Full Bore Flexible Wedge Welded Flange

High pressure Forged Gate valves

High pressure Forged Gate valves provide the ideal solution to solve any application problem connected with harsh service conditions, like elevated temperature and pressure ratings.

Features & Benefits:

• gate valves are manufactured by using exclusively high quality forged materials to guarantee a superior performance and to sensibly decrease operating costs and delivery times.
• Valve design in accordance with ASME B16.34, API 600, ISO, DIN, TRD, VGB, TRB, PED standards.
• Applicable for high pressure ratings (PN 720) and for temperature up to 650° C.
• Fully in compliance with the Health, Safety and Environment requirements to avoid any risk of fugitive emissions.
• Sempell valves are in conformity with the European Pressure Equipment Directive n°97/23/EC (CE mark 100% compliance).
• Extraordinary tightness obtained by a specific gasket design and packing in pure graphite.
• Technologically advanced pressure seal bonnet design is offered as standard to ensure a perfect body-bonnet tightness and to facilitate any maintenance operation.
• Standard configuration: flexible split wedge. The wedge guide is welding-free as integral to the valve body.
• Parallel slide configuration available upon request.
• Bolted bonnet design on request.
• Special constructions and materials available to suit any customers’ request​​​​​
