Vacuum gate valves manufacturers

Htc vacuum (HIGHLIGHT TECH CORP.)gate valves are appropriate for both HV and UHV applications and can be operated in pneumatic or in manual modes. Htc gate valves can be used with Cryo-Pumps, Turbomolecular Pumps or in any applications requiring clean, high life cycle, and low maintenance processing. Htc gate valves are available in all flange configurations, KF, ISO, ANSI, JIS, and CF.

Vacuum gate valve advanced service and support

Htc vacuum gate valve are available with various options to allow you to select exactly the features you need for your applications. You can add the roughing and gauge ports on the basic valve style.

Please refer to the left photo :
we added an elbow with a CF flange on the valve body to meet the special requirement of the customer. If you have any unique inquiry please contact us, we can discuss about the details of port type, size and location.

There are some critical applications of valves in Lab and research center which need RGA (Residual Gas Analyzer) data of valves to confirm the outgassing source of the system. Htc has the integrated RGA system with Inficon MPH100M analyzer with industry-leading data collection speed, minimum detectable partial pressure and signal-to-noise ratio. Htc is able to provide customers the RGA report for the price of the fixture and norminal labor charge.
