Marine manual proportional flow reversing speed regulating valve 35sfre-mo32b-h3
When referring to 35sfre, a manual proportional flow composite valve, people will think why there are two models of DN32 specification according to the selection table of this valve?
35sfre-mo32-h3 and 35sfre-mo32b-h3.
It can be seen from the above models that there is a "B" in the back, which means the code of the installation type. The difference is as follows:

With the development of the shipping industry, the old installation type has been gradually replaced by the new one, so the valve we now produce is mainly 35sfre-mo32b-h3.
Here we will give a brief introduction to this model of manual proportional flow valve:
35sfre-mo32b-h3 model meaning:

Three position five-way, the middle function is mo type (when the oil pump is in the middle position, the oil pump can unload; when the load is in the middle position, the ports a and B are fully closed), and the working pressure adjustment range is 8-20mpa.

Working principle of 35sfre-mo32b-h3 manual proportional flow compound valve:

It is a compound valve composed of a reversing speed regulating valve, a unloading valve and a pilot overflow valve. The manual control lever of the reversing speed regulating valve changes the angle, smoothly displaces the upper and lower non-polar positions of its main valve core through gear transmission, changes the direction of the load, and adjusts the speed of the load non-polar. (if the push cylinder is equipped at the control lever, remote control can be realized, which needs to be noted when ordering.).
When the control lever of 35sfre-mo32b-h3 manual proportional flow compound valve rotates to the right (or left), the main valve core moves upward (or downward), opening a (or port B), and the pressure oil enters the load to make it work in the forward direction (or in the reverse direction), and the return oil flows to the return port T through B (or a). The opening size of port a (or port B) determines the flow rate.

Precautions for use of 35sfre-mo32b-h3 marine manual proportional flow composite valve:

1. The displacement of the oil pump shall meet the requirements of the pneumatic proportional compound valve of the Institute.
2. "L" port shall be connected back to the oil tank separately.
3. When installing this manual proportional flow composite valve, the valve seat shall be fixed with screws on the processed foundation, and it is not allowed to support the valve with pipes.
4. When this 35sfre manual proportional valve is working, it is recommended to use No. 40 hydraulic oil, and the working oil temperature is 20 ℃ - 60 ℃.
5. During installation, check whether the inside of the system is clean and ensure that the connection is well sealed.
6. When the combination valve is used for multi-channel load, it is suitable to connect the system in series. Generally, the number of valves in series should be less than four to prevent excessive pressure loss. If it is used for multi-channel parallel system, please specify the special specifications when ordering, and select the middle oil pump and the non unloading valve group. At this time, it is recommended to select the pressure compensation variable displacement pump for the oil pump.

Assembly diagram of marine 35sfre-mo32b-h3 manual proportional flow valve:
From the physical appearance, this valve is very simple, but in fact, it is composed of 51 components in total (as shown in the following figure):

When none of the above conditions can be solved, we need to replace the entire proportional valve, which will bring us a problem. Because the nameplate on the proportional valve has been corroded for a long time, it is difficult to determine the exact model. At this time, we can accurately judge according to the following information:

The actual picture of the manual proportional flow reversing valve 35sfre-mo32b-h3 is as follows:

Marine manual proportional flow compound valve 35SFRE-OY25-H3

When it comes to the manual proportional valve, we all know that it is a valve that operates the windlass or steering gear on the ship. It is easy to operate and maintain.
At present, according to the development of our domestic ships, this manual proportional valve has two normal models:

Csbf manual proportional flow compound valve and 35sfre manual proportional flow directional valve
The working principle of the two models of manual proportional valves is the same, and the difference lies in the corresponding flow under the installation size and the same nominal diameter.

Here, we briefly introduce the 35sfre-oy25-h3 manual proportional flow composite valve
Model definition:

35 means this manual proportional composite valve is a three position five way type.
Sfre manual reversing proportional speed regulating valve
Oy is the middle position slide valve of this manual proportional flow valve: O means that the oil pump cannot be unloaded when the handle is in the middle position, y means that the load condition at the middle position is -port A and port B are fully open, and two-way floating is connected with port t.
25 means the nominal diameter is 25mm
H3 pressure setting range is 8-20mpa

According to the intermediate function of manual proportional valve -oy type, this series of valves can be marked as follows:

Oy is the middle position slide valve of this manual proportional flow valve: O means that the oil pump cannot be unloaded when the handle is in the middle position, y means that the load condition at the middle position is -port A and port B are fully open, and two-way floating is connected with port t.
