Rexroth Solenoid Valve Classification

Solenoid valves, both domestically and internationally, are classified into three main categories based on their operating principle (direct-acting, step-direct-acting, and pilot-operated). They are further subdivided into six subcategories based on differences in valve disc structure and materials, as well as their operating principles (direct-acting diaphragm structure, step-direct-acting diaphragm structure, pilot-operated diaphragm structure, direct-acting piston structure, step-direct-acting piston structure, and pilot-operated piston structure).

Direct-acting Solenoid Valve:

Principle: When energized, the electromagnetic coil generates electromagnetic force that lifts the closing element from the valve seat, opening the valve; when de-energized, the electromagnetic force disappears, and the spring presses the closing element back onto the valve seat, closing the valve.

Features: Can operate normally under vacuum, negative pressure, and zero pressure, but the nominal diameter is generally no more than 25mm.

Distributed Direct-Acting Solenoid Valve:

Principle: It combines direct-acting and pilot-operated principles. When there is no pressure difference between the inlet and outlet, energizing the valve causes the electromagnetic force to lift the pilot valve and the main valve's closing element sequentially, opening the valve. When the inlet and outlet reach the starting pressure difference, energizing the valve causes the electromagnetic force to actuate the pilot valve, increasing the pressure in the lower chamber of the main valve and decreasing the pressure in the upper chamber, thus using the pressure difference to push the main valve open. When de-energized, the pilot valve uses spring force or medium pressure to push the closing element downwards, closing the valve.

Rexroth Solenoid Valve Features: Reliable operation even at zero pressure difference, vacuum, or high pressure, but requires higher power and must be installed horizontally.

Pilot-operated solenoid valve:

Principle: When energized, the electromagnetic force opens the pilot orifice, causing a rapid drop in pressure in the upper chamber. This creates a pressure differential around the closing element, with lower pressure at the top and higher pressure at the bottom. The fluid pressure pushes the closing element upward, opening the valve. When de-energized, the spring force closes the pilot orifice. The inlet pressure quickly passes through the bypass orifice, creating a pressure differential around the closing element, with lower pressure at the bottom and higher pressure at the top. The fluid pressure pushes the closing element downward, closing the valve.

The Rexroth solenoid valve contains a sealed chamber with through-holes at different positions. Each through-hole connects to a different oil pipe. A piston is located in the center of the chamber, flanked by 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 orifices are opened or closed. The inlet orifice 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 on/off state of the electromagnet controls the mechanical movement.

Rexroth solenoid valve selection should first follow four principles in order: safety, reliability, applicability, and economy. Secondly, it should be based on six aspects of the on-site operating conditions (i.e., pipeline parameters, fluid parameters, pressure parameters, electrical parameters, actuation method, and special requirements).

Rexroth solenoid valve selection criteria:

1. Selecting the solenoid valve based on pipeline parameters: nominal diameter (DN) and connection type

1) Determine the nominal diameter (DN) based on the on-site pipeline inner diameter or flow requirement;

2) Connection type: Generally, >DN50 requires a flange connection; ≤DN50 can be freely selected according to user needs.

2. Selecting Solenoid Valves Based on Fluid Parameters: Material and 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 when the diameter is greater than DN25, these must be clearly distinguished.

4) Fluid viscosity: Generally, any viscosity can be selected below 50 cSt. If it exceeds this value, a high-viscosity solenoid valve should be selected.

3. Selecting Solenoid Valves Based on Pressure Parameters: Principle and Structural Types

1) Nominal pressure: This parameter has the same meaning as other general-purpose valves and is 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 valve must be selected; when the minimum working pressure difference is above 0.04 MPa, direct-acting, step-direct-acting, and pilot-operated valves can all be selected. 4. Electrical Selection: AC220V or DC24V voltage specifications should be prioritized for convenience.

5. Selection Based on Continuous Operating Time: Normally Closed, Normally Open, or Continuously Energized

1) When the solenoid valve needs to be open for a long time, and the duration 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, a normally open type cannot be selected; a continuously energized type should be chosen.
