What happens to the pressure in the pressure regulator when turned clockwise?

When the pressure regulator is turned clockwise, it typically adjusts the internal spring mechanism or diaphragm, which increases the tension against the incoming gas pressure. This adjustment results in an increase in the pressure on the outlet side of the regulator.

The increase in pressure occurs because the additional tension forces the diaphragm to close tighter against the inlet pressure, allowing less gas to escape. As a result, the pressure regulated at the outlet rises. Understanding how pressure regulators work is crucial in managing gas flow and ensuring that systems operate safely and efficiently, especially in contexts related to industrial gas applications, where precise pressure regulation is vital for proper functioning.
