Description
Description
Upstream pressure regulators are designed for automatic maintenance of the set pressure of the working medium (cold and hot water, steam, non-aggressive liquids) in pipeline systems upstream of the protected equipment. The principle of operation is based on the balance of forces: when the pressure increases upstream of the regulator the valve closes, and when it decreases - opens, providing maintenance of the set pressure at the inlet. The device is designed in normal closed version, which ensures that the valve remains closed in the absence of pressure.
