Transfer Valve Monovat Direct (Series 022)

For load lock / process module isolation. For 200mm, 300mm and 450mm semiconductor applications.

Specifications Table

Series Number	022
Series Name	Transfer Valve Monovat Direct
Description	MONOVAT denotes a three-dimensional seal technology, which allows to close an open with a single motion. Despite the very short opening and closing time it is possible to reach lowest value for the particle and shock generation. The extremely compact and maintenance-free drive covers the entire area, which is required in the semiconductor industry for load lock and process chamber insulation (200mm to 450mm). The exchange of the dynamic elastomer seal is very simple and without loose parts. In addition, the transfer valve MONOVAT supplemented with various options, such as heat shield, enclosure cooling, surface treatment and choice of elastomer seals (FKM, FFKM)
Actuator Types	Pneumatic actuator (double acting)
Sealing Technology	MONOVAT-System
Sealing Gate	FKM (VITON®)
Sealing Bonnet	FKM (VITON®)
Feedthrough	Bellows
Leak Rate - Body	< 1 . 10-9 mbar ls-1
Leak Rate - Seat	< 1 . 10-9 mbar ls-1
Nominal inside diameters (ID) in mm (inches)	32x222 (1.25"x8.75") - 56x496 (2,2"x19,53")
Body material	Aluminum; Stainless steel
