Manual proportional flow direction block valve for ship
Brief introduction of marine manual proportional valve manual
proportional flow direction compound valve manual proportion
composite valve:
The composite with CSBF type manual proportional flow direction
valve is a pressure compensation, flow rate regulation and safety
protection of the three position four way reversing valve,
synchronous action of CSBF type manual proportional control valve
operating handle and the flow adjusting mechanism can be stepless
speed, reversing and has good control performance, at the same time
with good reliability, convenient operation, long life and other
characteristics, the hydraulic system is widely used in ship
machinery and other machinery, the product won the national patent.
Manual replacement of CSBF type proportional flow direction
compound valve:
On board the replacement of the old ship CSBF manually proportional
flow direction composite valve, due to nameplate corrosion and
other factors, it is difficult for customers to clearly determine
the specifications of this valve. At this point, the customer can
proceed from our suggestion (the following chart) to facilitate
speculation:
model | Nominal dia.(mm) | Nominal flow(L/min) | Nominal pressure(MPa) | Scope of safety valve pressure(MPa) | Handle control force(N) | Mid-position pulley enginery |
CSBF-G20 | 20 | 120 | 25 | 5～25 | ≤40 | M O Y H K P |
CSBF-G25 | 25 | 200 |
CSBF-G32 | 32 | 300 |
CSBF-G40 | 40 | 450 |
CSBF-G50 | 50 | 700 |
CSBF-G65 | 65 | 1200 |

- 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
