Pneumatic actuator with a position control and position adjustment

A method for forming a proportional actuator valve, said method comprising:

• providing a valve housing;
• separating said valve housing into at east two chambers using a plurality of sealing members;
• positioning a valve slider within said valve housing;
• forming one or more bores in said proportional actuator valve;
• and
• forming one or more grooves in the proportional actuator valve, wherein said one or more grooves communicate with said one or more bores and with said at least two chambers.

A method for regulating pneumatic air to a pneumatic actuator, said method comprising:

• coupling an element to a pneumatic actuator, wherein a first force acts on said element and said pneumatic actuator provides a second three on said element opposite the first force;
• providing a proportional actuator valve, wherein said proportional actuator valve controls a supply of air to and from said pneumatic actuator;
• and
• wherein the proportional actuator valve comprises one or more grooves, wherein a cross sectional area open for air flow is determined by a change in the first force acting on said element.
