- Standard = VFR-S
- Economy = VFR-E
- Hi. Temp = VFR-HT
- Precision = VFR-P
- Heavy duty = VFR-HD
Rotary FT has 5 variations of design; each for a specific requirement. See below table.
Housing are made of Aluminum, except Hi Temp series which are all SST.
All rotary FT comes standard with a scale. “Economy Series” is a low cost version which does not have a scale. “Precision Series” is equipped with a precision micrometer.
Torque of Heavy Duty series can be as high as 240 in-lb.
Rotary FT : VFR

|Op. temp (C )||-20 to 150||-20 to 150||-20 to 315||-20 to 150||-20 to 150|
|scale resol||5 deg||5 deg||5 deg||5 deg||2 deg|
|Max Torque||125 in-oz||125 in-oz||125 in-oz||5 ft-lb||320 in-oz|
|Leak rate||1×10-9 standard cc/s|
- Magnetic Coupled
High Temp. : VFR-HT
Identical dimension as Standard (VFR-S) except equipped with all stainless steel body and housing.
Heavy Duty: VFR-HD
- 0.375 diameter shaft
- Manual or motorized
Miniature magnetic ally coupled rotary feedthrough is UHV compatible. It is the most economical FT of all . The trade off is not suitable for fast recipricating application.
