A proportional valve matched to your gas line
VISLAM designs and manufactures its own gas proportional valves. Multiple orifice sizes are matched to the customer’s pressure drop, flow and shut-off leak-rate requirements.

When closed, the leak rate can be controlled to the customer’s requirement.
How are pressure drop and flow matched?
The orifice size is chosen from the inlet pressure, outlet pressure and target flow so that it fits the actual gas line.
Can the shut-off leak rate be customized?
Yes, it can be controlled to your requirement. The leak-rate figure and test conditions are agreed according to the medium, the pressure difference and the seal fit.
