Oil and gas applications can involve higher pressure, temperature, fire risk and fugitive-emission requirements than general water service. The valve design must be matched to the duty.
Valve geometry
Double-offset or triple-offset designs may reduce seat wear and support demanding shut-off conditions.
Materials
Body, disc, shaft, seat and packing are selected for the fluid composition, corrosion and temperature.
Safety requirements
Project specifications may require fire-safe design, antistatic features, emissions qualification or SIL documentation.
Actuation
Define fail position, closing time, available utilities and emergency shutdown logic.
Information to include with an enquiry
Provide nominal size, pressure rating, medium, temperature, connection standard, materials, operating method, required testing and project documentation. Greysen will review the duty and confirm the final configuration in the approved data sheet.
