Pressure reducing regulators

Pressure reducing regulators, also known as pressure reducing valves, are mechanical devices which achieve automated pressure control without an external power source. Pressure reducing regulators reduce a high, often variable upstream pressure to a lower, steady outlet pressure despite varying flow demand from the equipment it is supplying. To match this demand, the pressure reducing regulator valve throttles, allowing more flow when demand increases and choking off flow when demand decreases. Pressure reducing regulators can be direct-operated or pilot-operated.

Pressure reducing valves are the most common method for reducing steam pressure and controlling steam flow, because they are the most cost-effective valve arrangement.

Here you can find pressure reducing regulators for liquid, steam or gas.
