The German HAWE solenoid valve has a sealed chamber with through-holes at different positions, each connecting to a different oil pipe. In the center of the chamber is a piston, and on either side are two electromagnets. When the coil of one electromagnet is energized, the valve body is attracted to that side. By controlling the movement of the valve body, different drain holes are opened or closed. The inlet hole is always open, allowing hydraulic oil to enter different drain pipes. The oil pressure then pushes the piston in the cylinder, which in turn moves the piston rod, which in turn drives the mechanical device. Thus, controlling the flow of current to the electromagnets controls the mechanical movement.

HAWE German Solenoid Valve Selection Criteria:

1. Selection of Solenoid Valves Based on Pipeline Parameters: Nominal Diameter (DN), Connection Type

1) Determine the nominal diameter (DN) based on the inner diameter of the pipeline or flow requirements.

2) Connection type: Generally, flange connections are required for DN > 50; for DN ≤ 50, the choice is flexible based on user needs.

2. Selection of Solenoid Valves Based on Fluid Parameters: Material, Temperature Group

1) Corrosive fluids: Corrosion-resistant solenoid valves and all-stainless steel valves are recommended; Ultra-clean edible fluids: Food-grade stainless steel solenoid valves are recommended.

2) High-Temperature Fluids: Solenoid valves made with high-temperature resistant electrical and sealing materials should be selected, and piston-type valves are preferred.

3) Fluid State: Fluids can be gaseous, liquid, or mixed, especially for diameters greater than DN 25.

4) Fluid Viscosity: Generally, any fluid can be selected below 50 cSt; if this value is exceeded, a high-viscosity solenoid valve should be used. 3. Selecting Solenoid Valves Based on Pressure Parameters: Principle and Structure

1) Nominal Pressure: This parameter has the same meaning as other general-purpose valves, determined by the nominal pressure of the pipeline.

2) Working Pressure: If the working pressure is low, a direct-acting or step-direct-acting principle must be selected. For a minimum working pressure difference of 0.04 MPa, direct-acting, step-direct-acting, and pilot-operated valves can all be selected.

4. Electrical Selection: AC220V and DC24V voltage specifications should be prioritized for convenience.

5. Selecting Based on Continuous Working Time: Normally Closed, Normally Open, or Continuously Energized

1) When the solenoid valve needs to be open for a long time, and the continuous time is longer than the closing time, a normally open type should be selected.

2) If the opening time is short or the opening and closing times are infrequent, a normally closed type should be selected.

3) However, for some safety protection applications, such as furnace and kiln flame monitoring, normally open valves cannot be selected; a continuously energized type should be chosen. 6. Select auxiliary functions according to environmental requirements: explosion-proof, check valve, manual operation, waterproof mist, water spray, and submersible.

German HAWE Solenoid Valve Performance Requirements

1. Reversing Performance

Under specified operating conditions, can the solenoid valve reliably reverse direction after being energized and reliably reset after being de-energized?

2. Pressure Loss

The pressure loss of a solenoid directional valve consists of flow loss and throttling loss generated when the fluid flows through the valve orifice.

3. Internal Leakage

The internal leakage of a solenoid directional valve refers to the leakage from the high-pressure chamber to the low-pressure chamber under specified operating conditions and in various operating positions.

4. Reversing and Reset Time

The time required from the energization of the solenoid to the termination of the valve core reversal; the reset time is the time required from the de-energization of the solenoid to the valve core returning to its initial position.

5. Switching Frequency

The maximum number of switching operations allowed per unit time.

6. Service Life

The lifespan of a solenoid valve is determined by the failure of its main components, rendering it unable to perform normal switching and reset actions, or by the significant deterioration of its main performance indicators exceeding the specified number of switching operations.

The German HAWE solenoid valve is an electromagnetically controlled industrial device, a fundamental component of automation used to control fluids. It is an actuator, not limited to hydraulic or pneumatic systems. It is used in industrial control systems to adjust the direction, flow rate, speed, and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the desired control, ensuring both precision and flexibility. There are many types of solenoid valves, each playing a different role in the control system. Common types include check valves, safety valves, directional control valves, and speed control valves.
