The working principle of the American MAC solenoid valve is a combination of direct-acting and pilot-operated principles. When there is no pressure difference between the inlet and outlet, upon energization, the electromagnetic force directly lifts the pilot valve and the main valve closing element sequentially, opening the valve. When the inlet and outlet reach the starting pressure difference, upon energization, the electromagnetic force actuates the pilot valve, causing the pressure in the lower chamber of the main valve to rise and the pressure in the upper chamber to fall, thus using the pressure difference to push the main valve open. When de-energized, the pilot valve uses spring force or medium pressure to push the closing element downward, closing the valve.

About MAC Valves Company:
MAC Valves was founded in January 1948 as Mechanical Air Control, with a capital of US$2,000. In 1962, the company name was changed to MAC Valves Inc.
Starting in 1964, MAC implemented an 18-month unconditional quality guarantee policy for all its products, printing this guarantee on its brochures and distributing them worldwide to emphasize the quality of MAC products. To date, no other manufacturer prints an 18-month quality guarantee on its brochures.
In 1971, MAC Valves Europe was established in Belgium as a branch of MAC Valves Inc.
In 1971, the Japanese government approved a manufacturing contract between MAC and SMC, under which MAC transferred technology to SMC and authorized SMC to produce solenoid valves in Japan. SMC also became MAC Valve's agent in the Asia-Pacific region. SMC was previously a filter manufacturer.
By 1972, MAC had sold one million valves; five years later, sales had doubled, exceeding two million by 1977.
In 1984, MAC Valves Pacific was established in New Zealand, a branch of MAC Valve, responsible for sales and service in the Asian and Australian markets.
