This type of product has five main elements:

■ a machined body with pressure connections

■ a piston which slides within the body and regulates the flow of fuel

■ springs to control the movement of the piston

■ an electrical solenoid to move the piston

■ Limit switches to regulate the movement of the piston. 

Produce a short report explaining some of the strategies which can be used to improve the cost-effectiveness of producing a manufactured product. Use either the valve detailed above or a product with which you are familiar with; (possibly from your place of work).
