Marine CSBF type manual proportional flow direction compound valve - instructions for ordering:

Our CSBF type manual proportional flow direction compound valve is normally factory M type, middle function (normal omission), if the user needs other medium functions and special requirements, should be put forward in order to supply.

Marine type CSBF manual proportional flow direction compound valve, Lieutenant function is M type, expressed as:

When the handle of the manual proportional valve is in the middle position, each oil port (A, B port) is closed, and the oil which is removed from the oil pump is returned to the O port from the P port. At this time, the motor stops operation.

Technical requirements for marine manually operated proportional flow directional compound valves:

1, manual proportional composite valve of the main components and materials should comply with the provisions of the following table:

2, the body, the spool should be in line with the GB/T1184 7 tolerance, surface roughness is not greater than 0.8 m,

3, the sealing surface between the valve body and the valve core should not be scratched, air holes, bumps and other defects,

4, the O ring shall comply with the GB3452.1

5, the composite valve should have good cleanliness, all parts should not burr, cutting and other casting residues

6, the composite valve inlet and outlet, access flange, screw performance level should not be less than 9.8
