Can gate valves be used for heat transfer oil pipelines?

Reply #22017-12-16

A bellows-type stop valve is used, and the heat transfer oil has strong permeability

For oil injection and oil return, use gate valves for small pipes with a diameter of one inch or less

Globe valves should be used for the heat transfer oil circulation pipes, while gate valves can be used for other tasks such as oil injection and oil drainage.

Seal the globe valve with a bellows. Advantage: low price. The downside is high pressure drop loss. Leave more surplus.

Another point is why the pressure rating of the valve should be set one level higher; the maximum pressure is only 1.0 MPa, while the design pressure is 2.5 MPa
