Composite valve with manual proportional flow direction for ship
Proportional flow direction block valve for ship Manual
Marine manual proportional valve - Manual proportional flow directional composite valve - Manual proportional 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.
