Pressure Reducing Valve

AKO pressure reducers without auxiliary energy refer to the force required for pressure control from the medium to be controlled. The pressure adjustment takes place with the aid of the pretensioning of a setpoint spring. The controller is designed for liquids and non-flammable gases. As a seal, depending on the application, metal bellows seals or a membrane seal are used.

The valve is controlled by means of the force compensation between the force specified by the setpoint spring and the force resulting from the medium pressure. If the set back pressure is reached, the valve closes.

Pressure Overflow Valve

AKO overflow valves without auxiliary energy refer to the force required for pressure control from the medium to be controlled. The pressure adjustment takes place with the aid of the pretensioning of a setpoint spring. The controller is designed for liquids and non-flammable gases. As a seal, depending on the application, metal bellows seals or a membrane seal are used.

The valve is controlled by means of the force compensation between the force specified by the setpoint spring and the force resulting from the medium pressure. When the set pre-pressure is reached, the valve opens.

Differential Pressure Regulator

AKO differential pressure controllers without auxiliary energy refer to the force required for the pressure control from the medium to be controlled. The pressure adjustment takes place with the aid of the pretensioning of a setpoint spring. The controller is designed for liquids and non-flammable gases. As a seal, depending on the application, metal bellows seals or a membrane seal are used.

The pre-pressure (P1) and the holding pressure (P2) of the medium used are fed to the inside or the outside of the control diaphragm via two lines. The resulting force acts against a setpoint spring, the pre-tensioning of which sets the desired differential pressure. If the preset value is exceeded, the valve opens until the setpoint is reached again.
