TFU006 Pressure Regulator
Brand: Burkert Fluid Control Systems
The water pressure regulator works on the principle of pressure reduction. It is preferably for use in the provided water systems.
The pressure regulator consists of a housing, a piston or diaphragm valve with an adjustable spring and a spring cap. The inlet pressure reaches the target value, opens the piston or diaphragm against the spring force of the control valve and builds up the output pressure.
The output pressure is the controlled variable. When exceeding the nominal value the valve closes, when there is a shortfall the valve opens and thus the output pressure is kept almost constant. By changing the spring tension, the spring setpoint can be continuously adjusted.
