MAC solenoid valve 57D-81-RA (USA) in stock.
$241.05
The electromagnetic components of MAC solenoid valves from the USA consist of a fixed iron core, a moving iron core, and a coil; the valve body comprises a spool, a spool sleeve, and a spring base. The solenoid coil is directly mounted on the valve body, which is enclosed in a sealing tube, forming a simple and compact assembly. Commonly used solenoid valves in production include 2-position 3-way, 2-position 4-way, and 2-position 5-way valves. Here, let's first explain the meaning of "2-position": for a solenoid valve, it means energized and de-energized; for the valve it controls, it means open and closed.

A malfunction of a MAC solenoid valve will directly affect the operation of switching and regulating valves. Common malfunctions include the solenoid valve not operating. The following troubleshooting steps should be taken:
1. Loose or detached solenoid valve wiring. The solenoid valve will not receive power. Tighten the wiring.
2. Burned-out solenoid valve coil. Disconnect the solenoid valve wiring and use a multimeter to measure. If an open circuit is detected, the solenoid valve coil is burnt out. This can be caused by moisture in the coil, leading to poor insulation and magnetic leakage, resulting in excessive current and burnout. Therefore, prevent rainwater from entering the solenoid valve. Additionally, an overly stiff spring, excessive reaction force, or insufficient coil turns can also cause coil burnout. In an emergency, the manual button on the coil can be switched from the normal "0" position to the "1" position to open the valve.
3. Solenoid Valve Jammed: The clearance between the solenoid valve's spool sleeve and valve core is very small (less than 0.008mm), and it is usually assembled as a single piece. When mechanical impurities are introduced or there is insufficient lubrication, it can easily become jammed. A temporary fix is to insert a steel wire through the small hole at the head to make it spring back. The fundamental solution is to disassemble the solenoid valve, remove the valve core and valve core sleeve, and clean them with CCI4 to ensure the valve core moves freely within the valve sleeve. During disassembly, pay attention to the assembly sequence of each component and the location of external wiring to ensure correct reassembly and wiring. Also check if the lubricator spray hole is blocked and if there is sufficient lubrication.
4. Air Leakage: Air leakage will cause insufficient air pressure, making it difficult for the forced valve to open and close. This is caused by damaged gaskets or worn spool sleeves, resulting in air leakage between several cavities. When troubleshooting solenoid valve malfunctions in switching systems, choose an appropriate time to address the issue when the solenoid valve is de-energized. If the problem cannot be resolved within one switching interval, pause the switching system and address the issue at a later time. 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 has printed 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 Corporation of Japan, under which MAC transferred technology to SMC and authorized SMC to manufacture solenoid valves in Japan. SMC also became MAC Valves' agent in the Asia-Pacific region. SMC was previously a filter manufacturer.
In 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 Valves responsible for sales and service in the Asian and Australian markets.
MAC Valves is an employee-owned company with over 1,300 employees worldwide.
Over the past six decades, MAC's technology in designing and developing equipment has successfully created highly competitive products with superior advantages for industrial automation applications.
