Parker solenoid valves are electromagnetically controlled industrial devices, fundamental components of automation used to control fluids. They are actuators, not limited to hydraulic or pneumatic systems. They are 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. The most common are check valves, safety valves, directional control valves, and speed control valves.

Parker Solenoid Valve Selection Considerations

Selection Basis

Parker 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). Selection Criteria:

1. Selecting 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, for DN > 50, a flange connection should be selected; for DN ≤ 50, the connection type can be freely selected according to user needs.

2. Selecting 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 should be chosen.

3) Fluid State: Fluids can be gaseous, liquid, or mixed, especially when the diameter is greater than DN 25, it is essential to distinguish between these states.

4) Fluid Viscosity: Generally, any choice is acceptable 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 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.

The Parker 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. Controlling the movement of the valve body opens or closes different drain holes. 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 current to the electromagnets controls the mechanical movement.

1. When installing a Parker 2-position 5-way solenoid valve, ensure the arrow on the valve body aligns with the direction of media flow. Do not install in areas with direct dripping or splashing water. The Parker 2-position 5-way solenoid valve should be installed vertically upwards.

2. The Parker 2-position 5-way solenoid valve should operate normally within a power supply voltage fluctuation range of 15%-10% of the rated voltage. 3. After installation, the Parker 2-position 5-way solenoid valve must not have a reverse pressure differential in the pipeline. It needs to be energized several times to allow it to reach the set temperature before being put into formal use.

4. Before installing the Parker 2-position 5-way solenoid valve, the pipeline should be thoroughly cleaned. The medium introduced should be free of impurities. A filter should be installed before the valve.

5. When a Parker 2-position 5-way solenoid valve malfunctions or requires cleaning, a bypass device should be installed to ensure continued system operation.
