HDS Manual Gate Valves
Remosa designs and manufactures manual gate valves for hydrodesulphurisation plants (HDS).
A gate valve is a linear valve that uses a flat closure element perpendicular to the process flow, which slides into the flow steam to provide shutoff.
The gate valve is designed for on-off service in either liquid or gas service (with entrained solid, granules and powders), cryogenic and vacuum service.
Valve body is made from a forged piece of Low Chrome Alloy internally lined with a first buttering layer and a second layer against hydrogen induced cracking (HIC) for a total overlay thickness of 5.5 mm. Disc and seats are hardfaced by Stellite #1 to avoid catalyst erosion.
Remosa's manual gate valves are designed in accordance with:
- American Society of Mechanical Engineers (ASME) B31.3, Process Piping;
- American Society of Mechanical Engineers (ASME) Section VIII, Division 1, Rules for Construction of Pressure Vessels;
- American Society of Mechanical Engineers (ASME) Section VIII, Division 2, Boiler and pressure vessel Code for Finite Element Analysis.
The valve can be supplied with CE stamp in accordance with the European Pressure Equipment Directive (PED: 97/23/EC) in conformity with Module G and European Directive for Equipment and Protective Systems in potentially Explosive Atmospheres (ATEX: 94/9/EC).
