Page 10: Piping
Kobelt 2588 control valves are equipped with “U” cups and “O” rings and therefore require lubrication in order to provide long service life. Unlubricated seals will have excessive friction and wear. The oil that is required for the lubricator should be a hydraulic type with a viscosity grade of 10 to 32 centistokes. -
Page 11: Brake System Plan
RAKE YSTEM Below is a piping diagram depicting how to utilize the Kobelt 2588 Driller’s valve in a hoist braking system. When implementing the two-channel 2588-D valve, it is recommended to plumb through a Barksdale 9001-M-G-D diverter valve to alternate the braking between the two discs at light loads. The diverter valve must have an open center position spool. -
