Set to trip on either an increasing or decreasing control signal, the Mite 70 will vent one port to atmosphere while it locks up the pressure in a second line. The tripped position is then held indefinitely until the control signal is restored and a manual reset button is pushed. The trip point is adjustable from 1 to 100 psi with a simple screw stem. The Mite 70 can also be tripped on demand from a separate remote signal. Use the Mite 70 to open safety valves in emergency situations, trigger an alarm while locking up a valve or actuate diaphragm motor valves, air cylinders or other pneumatic actuators. The Mite 73 is similar in design and function to the Mite 70. A sensitive line monitoring diaphragm and up to four inputs allow even more versatility. When tripped by either an increasing or decreasing signal, one output is vented to atmosphere while the other is locked up. The Mite 73 can be tripped by remote and is also capable of being reset pneumatically for fully automated control.

The Mite 85 allows you to establish two adjustable trip points that control flow through a 3-way valve. An increasing signal that exceeds the high trip point will open “I†port to “Hâ€. A decreasing signal pressure that drops below the low trip point will vent port “Hâ€. This switching action is reversible and repeatable without having to manually reset. Use the Mite 85 to passively switch to a secondary controller in case the primary system fails.

High pass or low pass pneumatic selecting relay. The Super Mite 71 will automatically select the higher or lower of two pneumatic inputs and pass it downstream while blocking the other. Capable of almost instantaneous selection, the Super Mite 71 can separate pressure differentials as low as a tenth of a psi. Although ordered as either high or low pass, the Super Mite 71 can easily be converted in the field from one to the other. The Super Mite 71 can be relied on to open or close valves when a signal pressure drops or rises past a determined value. They can also be used to prevent a valve from opening or closing beyond a critical point.
