Manual Direction Proportional Flow Control Valve
35SFRE manual proportional compound valve - manual manual reversing proportional speed regulating valve:
On board the replacement of the old 35SFRE manually proportional 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:
35SFRE manual proportional compound valve - Marine manual reverse proportional valve - Manual proportional windlass operating valve profile:
35SFRE ship with manual reversing proportional control valve is three position five way valve has excellent response characteristics and pressure compensation function; pressure compensation valve suppress load impact, flow system will not because of pressure fluctuations and volatility, and provide stable power;
The bypass compensator is used to avoid the reverse impact; in addition, the 35SFRE marine manual reversing proportional speed regulating valve has a compensator with high response characteristics, and is suitable for occasions with load impact.
35SFRE marine manual reverse proportional speed regulating valve, shipboard manual proportioning compound valve, performance characteristics:
n, stepless speed regulation, unloading and overload protection. The utility model has the advantages of simple structure and reliable operation
2, this section of 35SFRE manual proportional reversing valve, manual regulation of smooth, sensitive, reversing and stepless speed regulation synchronization
3, M type manual proportioning valve valve pump output power and motor (cylinder) load power matching, energy-saving effect is prominent, suitable for single valve or multi valve series
4, O type manual proportional flow composite valve in place without unloading, suitable for multi valve parallel connection

35SFRE manual proportional compound valve, manual proportional reversing speed valve shape and installation dimensions:
35SFRE manual proportion compound valve, manual proportional reversing speed regulating valve, maintenance notice:
1, pump displacement shall comply with the proportion of the competitors, composite valve flow requirements
2, "L" accent alone back to the oil tank
3, in accordance with the valve seat should be fixed with screws on the basis of processing, do not allow the use of piping, the valve
4. It is recommended to use No. 40 hydraulic oil with a working temperature of 20 DEG C -60 DEG C
5 the installation should check whether the system is clean and ensure good sealing at the joint
6, when the combination valve for multiple load, suitable for the series system, the series general should be less than 4, to prevent the loss of pressure is too large; if for a parallel system, please order that special specifications, in the selection of a pump without unloading valve, the pump pressure compensated variable displacement pump is recommended
