TESCOM WEGA-SP 调压阀
连接件数量减少，从而*大程度地降低氦气泄漏率。
TESCOM WEGA-SP pressure regulating valve
The WEGA-SP (single*) pressure regulator provides an integrated purge function (including a shut-off valve and a check valve), specifically suitable for corrosive or toxic gases and gas mixtures. The integrated purge equipment can effectively remove residual moisture, oxygen, and remaining process gases.

function
Compact design, eliminating the need for external purge equipment. Reduced weight, internal volume, and installation length. Ideal for laboratory use.
*The body-type purge valve and check valve achieve effective purging with minimal consumption of purge gas, greatly reducing the risk of corrosion.
Residual moisture and external gases have been eliminated before the start-up process, thus reducing the usage of expensive calibration and test gases.
The optional integral valve membrane "positive sealing" design provides additional shut-off support for corrosive gases. Hastelloy valve internals and diaphragms are provided to reduce corrosion and extend service life.
The number of connecting pieces is reduced, thereby minimizing the helium le
