CD04-5/2XX-SR-RLD-G018-G018-S

AVENTICS directional control valves are directional control valves with two or more flow patterns and two or more ports. They are valves used to achieve the communication, cut-off, and reversal of hydraulic oil flow, as well as pressure unloading and sequential action control. They are directional control valves that rely on the relative movement of the valve core and valve body. There are rotary valve and spool valve types. They are classified according to the number of working positions the valve core stays in the valve body, such as 2-position and 3-position; according to the number of oil passages connected to the valve body, such as 2-way, 3-way, 4-way, and 6-way; the valve core can be operated manually, mechanically, electrically, hydraulically, or electro-hydraulic.

AVENTICS directional control valve working principle:

The AVENTICS directional control valve is mainly composed of valve body, sealing components, cam, valve stem, handle, and valve cover (Figure 1). The valve is driven by the handle, which drives the valve stem and cam to rotate. The cam has the functions of positioning, driving, and locking the opening and closing of the sealing components. When the handle is rotated counterclockwise, the two sets of sealing components close the two lower channels under the action of the cam, and the two upper channels are connected to the inlet of the pipeline device. Conversely, the two upper channels are closed, and the two lower channels are connected to the inlet of the pipeline device, realizing non-stop directional control.

(1) The valve body of the six-way valve is divided into two chambers by a partition. Each chamber has three channels, with the oil inlet in the middle and the oil outlets at both ends. The valve body is a carbon steel plate welded structure, which is small in size, light in weight, and compact in structure, improving material utilization, shortening the production cycle, and reducing costs. The sealing surface is welded with stainless steel, which is rust-proof and corrosion-resistant. After precision machining, the sealing surface is polished and ground, with a surface roughness Ra≤0.8μm.

(2) The six-way valve has two sets of sealing components. Each set of sealing components (Figure 2) consists of a valve disc, sealing ring, adjusting block, adjusting screw, clamping plate, and bolts. The valve disc is a welded carbon steel plate with reinforcing ribs, which increases the strength of the valve disc and also serves as a guide, ensuring the coaxiality between each set of valve discs. A polyurethane rubber ring is embedded on the valve disc. This material has the characteristics of oil resistance, wear resistance, stable performance, good sealing, and long service life. Under the action of the cam, the spherical surface of the sealing ring contacts the sealing surface of the valve body, generating extrusion elastic deformation to achieve the sealing effect. The adjusting block and adjusting screw can play an adjustment role when the two sets of sealing components cannot be in place synchronously, ensuring that the sealing performance of each channel is in place synchronously.

(3) The axial seal between the valve stem and the valve body partition and upper valve cover adopts an O-ring. (4) Copper sleeves are inlaid in the valve body partition and upper valve cover shaft hole areas to reduce the frictional torque with the O-ring, ensuring smooth opening and closing of the sealing assembly with low operating torque.

(5) The upper valve cover is equipped with an indicator plate and limit screws, and a pointer is installed on the valve stem to clearly indicate the connection status of each channel, facilitating operation. AVENTICS Directional Control Valve
