Model Numbers

Model Model Number Description
Basic Valve B Can be actuated by any type of moving linkage. The spool ends are threaded for ease of adapting to your connection. Spool ends are provided with stroke adjustment nuts with "micrometer barrel" type thread which can be used to restrict spool travel so flow through the valve can be adjusted in both directions.
Spring Loaded BSL This is a spring-loaded version of the basic valve designed for straight line actuation. It comes standard with a 10 lb. spring. Two lighter weight springs and one heavier are available upon request. Spool end adaptors may be used to restrict spool travel as noted above with the basic valve.
Spring Loaded Ball Point BB The ball point, spring-loaded valve is used for actuation via a cam. The rolling ball tip provides for operation via sliding or rolling of a cam in almost any plane in addition to straight line actuation. It comes standard with a 10 lb. spring. Two lighter weight springs and one heavier are available upon request.
