Disclosed is method for regulating pneumatic air to a pneumatic actuator (100). The method comprises the following steps: · Coupling an element (104) to the pneumatic actuator (100), wherein a first force acts of the element (104) and the pneumatic actuator (100) provides a second force on the element (104) opposite the first force; and · Providing a proportional actuator valve (110) wherein, the proportional actuator valve (110) controls the supply of air to and from the pneumatic actuator (100). The proportional actuator valve (110) comprises one or more grooves with non-uniform cross sectional areas, wherein the cross section areas. The cross sectional areas that open for air flow is determined by a change in the first force acting on the element (104).
