Purpose and features:
The BR.W511 direct acting self operated pressure regulator (referred to as the pressure regulator) is a type of valve that utilizes the pressure changes of the controlled medium to drive the actuator without the need for external energy to achieve pressure regulation. It can work in situations without electricity or gas.
Pressure regulators are mainly suitable for reducing pressure and stabilizing steam, as well as pressure stabilizing devices for various gases and low viscosity liquid media.
Pressure regulators are widely used in automatic control in industrial sectors such as chemical, petrochemical, metallurgical, power plants, and textiles.
