Determining the design of valves

The greatest challenge is to determine the design of the valves. Our valves are designed for a wide variety of operating conditions in order to withstand the extreme mechanical, chemical and thermal loads and assure optimum heat dissipation.
		Materials Austenistic steels Martensitic steels Types Mono-metal valves Bi-metal valves Valve seat Plasma powder facing Induction hardening Valve tip induction hardening Profile hardening Through-hardening Tip surface hardening Hollow valves: Stem size: > 6 mm Bore sealing: - Laser welding - Friction welding Sodium-filled Fillet profile Turned, ground As forged Head top surface Machined As forged With or without spherical indentation
		Valve tip geometry 1–3 grooves Special designs Valve length 80–210 mm Valve head diameter 18–65 mm Valve stem diameter 5–12 mm Surface treatment Salt bath nitrided Hard chrome plated (coating thickness: 3–35 µm)
