Stainless Steel High Vacuum Angle Valves / In-Line Valves, XMH/XYH Series (Manual/Bellows Seal) (XYH-25-XR3A)

Stainless Steel High Vacuum Angle Valves / In-Line Valves, XMH/XYH Series (Manual/Bellows Seal) XYH-25-XR3A

A vacuum valve with a pressure-balanced structure that enables an unrestricted exhaust direction.
[Features]
· Bellows type is particulate-free and cleaned.
· Low actuation torque (0.5 N·m or less).
· Spring provides a standard sealing load.
· Handle height remains the same regardless of whether valve is open or closed.
· Equipped as standard with an indicator for confirming if the valve is open or closed.
· Body material: SCS13 (SUS304 equivalent).
· Precision-cast single-piece structure which helps prevent gas accumulation.
· The XM Series is interchangeable with XL Series aluminum high vacuum angle valves.

*Refer to the manufacturer's catalog for maintenance parts.

Notes

  • *The body material is SCS13 (SUS304 equivalent), the bellows material is SUS316L and the metal material used for other vacuum parts is SUS304. The standard seal material for vacuum parts is FKM, but it can be changed for other materials (see section on part number notation). Check that the fluid in use will not damage the selected material.
  • *Select a heat resistance for the actuation pressure tubing materials and fittings that is appropriate for the given operating temperature.
  • *Refer to the manufacturer's catalog for parts other than those detailed above.
