Used in ultra-high vacuum systems or low-temperature systems where elastic sealing valves cannot be used at extreme temperatures.

The working temperature range is 450 ° C to -250 ° C

The maximum temperature baking service life is 50 times to open,

Medium baking service life ≈ 200 times of opening.

The dial gauge at the top of the valve can indicate the correct closing torque and when the seal should be replaced.

Can operate at low temperatures

Vacuum degree: 1.0 * 10-11 pallets

All metal sealing structure

Assembly of Class 10000 cleanroom

Leakage rate: ≤ 1.0 * 10-11 std. cc/sec

Provide two types of flange interfaces: CF16 and CF35

Equipped with a dial indicator for closing

We can provide 2D/3D models and accept non-standard customization. If you have any needs, please consult the sales engineer.

be careful:

1. Do not exceed the maximum torque specification.

2. It is easy to replace the seal of the lift valve with a straight screwdriver.

3. After replacing the seal, the valve must be tightened to a higher torque value than during normal operation to ensure it is in place.

4. After closing the valve to the normal torque value, loosen the positioning screw below the closing nut, rotate the indicator counterclockwise to the farthest line at the top of the valve, and then tighten the positioning screw again. The valve can be closed almost infinitely to this mark.

5. Regularly check with a torque wrench to indicate valve seat wear and correct markings for alignment. When the indicator reaches the last mark, it is recommended to replace the seal.
