Features

• All valves are equipped with high temperature Inconel® springs as standard equipment.
• Disc is fully guided and vented for accurate seat contact, smooth operation and maximum lift.
• Spring-loaded disc ensures positive closure, regardless of mounting position.
• The stainless steel disc is hardened, ground and lapped to ensure leak-free sealing over the valve’s full pressure/ temperature range.
• All internal surfaces are accurately machined to provide maximum performance.
• Seat is overlaid with stellite or equal hardfacing.
• The integral seat hardfacing is overlaid directly on to the base material, eliminating any possibility of leakage behind the seat.
• Flat, precision machined and lapped seating surfaces eliminate damage from high impact seating.
• Socket weld and butt weld ends are available as standard.
• Standard body materials are carbon steel (ASME SA 105), alloy steel (ASME SA 182 gr. F22) and stainless steel (ASME SA 182 gr. F316).
• All standard valves are made from one-piece die forged bodies.
• Bonnets and discs are machined from barstock.
