Below is a list of Vacuum Switches manufacturers from Kirtland, Ohio. Vacuum switches help regulate the pressure between two closed cavities by converting a negative pressure signal to an electrical output. As a safe and cost-effective alternative to safety relief valves, vacuum switches are able to work with gas, electric current and liquid pressure situations, individually or in a combination. In addition, pressure vacuum switches will detect when a problem, such as leaking pressure during operation, is happening and will shut down the process until the trouble is fixed and an operator restarts the operation.
