German SAMSON valves SAMSON models SAMSON prices

SAMSON valves are directional control valves with more than two flow patterns and more than two oil ports. They are valves that enable communication, cutoff, and reversal of hydraulic oil flow, as well as pressure unloading and sequential action control. These are directional control valves that rely on the relative motion between the spool and the valve body. There are two types: rotary valve and slide valve. They are classified into two-position, three-position, etc., based on the number of working positions where the spool stays within the valve body; they are classified into two-way, three-way, four-way, and six-way, etc., based on the number of oil circuits connected to the valve body. The methods for operating spool movement include manual, mechanical, electric, hydraulic, and electro-hydraulic types.

SAMSON valve operating principle

The six-way reversing valve mainly consists of components such as the valve body, sealing assembly, cam, valve stem, handle, and valve cover (Figure 1). The valve is driven by the handle, which rotates the valve stem and cam. The cam has the function of positioning drive and locking the opening and closing of the sealing assembly. When the handle is rotated counterclockwise, the two sets of sealing components close the two lower channels under the action of the cam, while the two upper channels communicate with the inlet of the piping system. Conversely, the two upper channels are closed, and the two lower channels communicate with the inlet of the piping system, achieving reversal without stopping.

SAMSON valve advantages

Accurate action, high degree of automation, and stable and reliable operation, but it requires additional drive and cooling systems, resulting in a more complex structure; the disc-type structure is simpler and is mostly used in production processes with smaller flow rates. In industries such as petroleum, chemical, mining, and metallurgy, the six-way reversing valve is an important fluid reversal device. This valve is installed in the pipelines of thin-oil lubrication systems that transport lubricating oil. By changing the relative position of the sealing components within the valve body, the various channels of the valve body are connected or disconnected, thereby controlling the reversal and start/stop of the fluid.

SAMSON valve functions and applications

Reversing valves, also known as Christ valves, are a type of valve with multi-directional adjustable channels that can change the direction of fluid flow as needed. They can be divided into manual reversing valves, solenoid reversing valves, electro-hydraulic reversing valves, etc. During operation, the drive transmission mechanism outside the valve rotates the drive shaft, which drives the rocker arm to activate the valve plate. This allows the working fluid to alternately flow from the left inlet to the lower outlet of the valve, or from the right inlet to the lower outlet, achieving the purpose of periodic flow reversal. This type of reversing valve is widely used in petroleum and chemical production, and is most commonly used in synthetic ammonia gasification systems. In addition, reversing valves can be made with a disc-type structure, mostly used for occasions with smaller flow rates. During operation, only the handwheel needs to be turned to change the direction of the working fluid via the valve disc.
