Check, Shuttle, and Quick Exhaust Valves
Humphrey strives to provide our customers with the most complete offering of valving equipment needed for pneumatic applications. Our compressed air control valve line up includes these ancillary valve components:
Quick Exhaust Valve Features
Humphrey’s versatile, Super Quick Exhaust valves redirect the exhaust or expulsion of compressed air to a high flow piped third port. Their primary purpose is to enhance the performance and life of air cylinders and air actuators by quickly sensing upstream pressure differential and redirecting downstream exhausting air.
Humphrey Super Quick Exhaust valves feature an engineered molded rubber shuttle that outperforms/outlasts competitive rubber “sheet stock” designs. Our world-renowned Super Quick Exhaust line-up consists of six models ranging from 1/8 thru 3/4 PIPE size. A miniature 10-32 UNF port size from our TAC Miniature Air Logic Components completes the offering.
Use Humphrey Super Quick Exhaust as is, or as a rugged shuttle valve solution. Consider it for check or flow control functions with piping additions to the exhaust port.
Shuttle Valve Features
Shuttle valves allow compressed air to flow from one of two sources, delivering each path to its common out port. Typical applications include function controls from multiple locations and introducing various pneumatic media or pressure.
Shuttle valves are available from our TAC Miniature Components and from our range of “Humphrey Quick Exhaust” valves available in 1/8 thru 3/4 PIPE sizes.
Check Valve Features
Check valves allow compressed air to flow in one direction and prevent reverse flow. These one-way valves are used in applications where backflows are not permitted or must be redirected. Check valves are available in 10-32 UNF and 1/8 PIPE ports from the miniature TAC Series. Our “Humphrey Quick Exhaust” valves become excellent check valves by plugging the exhaust port.
Specialty check valves from our Classic Diaphragm-Poppet Series include an air pilot feature to override the checking function.
