HAWE Directional Control Valve Introduction

The HAWE directional control valve, also known as a Kreutz valve, is a type of valve with multi-directional adjustable channels, allowing for timely changes in fluid flow direction. It can be categorized into manual directional control valves, solenoid directional control valves, and electro-hydraulic directional control valves.

During operation, an external drive mechanism rotates the drive shaft, which in turn moves the rocker arm, actuating the valve plate. This causes the working fluid to flow from the left inlet to the lower outlet of the valve, and vice versa, achieving the purpose of periodically changing the flow direction.

This type of valve has wide applications in petroleum and chemical production, and is most commonly used in synthetic ammonia gasification systems. In addition, directional control valves can also be made with a disc-type structure, often used in applications with smaller flow rates. During operation, simply turning the handwheel changes the flow direction of the working fluid through the disc.

Working Principle of HAWE Directional Control Valve

The six-way 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 the utilization rate of materials, 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 to reduce the frictional torque with the O-ring, ensuring flexible opening and closing of the sealing assembly and 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, making it easy to operate.

HAWE 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 two types: rotary valve and spool valve. According to the number of working positions the valve core stays in the valve body, they are divided into two-position, three-position, etc.; according to the number of oil passages connected to the valve body, they are divided into two-way, three-way, four-way, and six-way, etc.; the methods of operating the valve core movement include manual, motorized, electric, hydraulic, and electro-hydraulic types. BVG, BVE, and BVP type shut-off directional valves are classified into two specifications: 2/2 and 3/2 valves. Specification 1 provides the NBVP type structure with standard connection diagram (NG 6) as well as the 4/3 valve. They are designed as leak-free, sealed cone valves. Due to the internal static pressure balance, all interfaces can be loaded. Valves can be pipe-connected (BVG type), custom-made plate-connected (BVP type), standard plate-connected (NBVP type), or installed in a custom-made valve block as a screw-type cartridge valve (BVE type). Different operating methods (electrically operated BVE type only) open up a wide range of applications for this type of valve. Other components within the valve block for P, R, A, B interfaces (e.g., throttle valves, check valves, or one-way throttle valves) expand the application range for special applications.
