Mite Series 70/71/73/74/85 - Snap-acting, Pneumatic Relays - 1

Mite Series 70/71/73 74/85 The Mite Series of pneumatic relays offer precise control of air or gas service. Their snap-acting design automatically trips on either an increasing or decreasing signal. Mites are rugged, compact units engineered for high density applications. They are constructed to last and “make decisions” with crisp precision, cycle after cycle. Snap-acting control relay with manual reset Will either lock-up or vent control pressure to a valve when tripped High pass or low pass pneumatic selecting relay Automatically selects the higher or lower of two input signals Snap-acting air signal monitor Accepts up to four inputs and can be reset automatically Snap-acting control relay with integral 3-way or 2-way valve Combines a Mite 70 with a precision 3-way or 2-way valve Snap-acting 3-way valve with two trip points Automatically activates back up controller if primary fails Snap-acting, Pneumatic Relays Compact, rugged and precise “decision-making” switches

Built to “make decisions” with crisp precision cycle after cycle. S P E C I F I C AT I O N S M I T E 7 0 , 7 1 , 7 3 , 7 4 , 8 5 The Mite series of pneumatic relays are engineered to switch, lock or vent various ports based on either an increasing or decreasing pneumatic signal. Their passive design, as well as precise, unerring and immediate decision making abilities make them the ideal solution to critical safety and emergency process controls found in the petroleum, chemical, gas-field or pharmaceutical industries. Their rugged, simple construction provides uncompromising reliability and...

Mite Series 70/71/73/74/85 - Snap-acting, Pneumatic Relays - 3

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 74 combines the Mite 70 control relay with a precision 2-way or 3-way valve in a single compact package. Either an increasing, decreasing or remote signal can be used to channel air as needed. The...

Mite Series 70/71/73/74/85 - Snap-acting, Pneumatic Relays - 4

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 “H”. A decreasing signal pressure that drops below the low trip point will block "I" and vent port “H”. 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.
