PARKER Solenoid Valve Selection Criteria

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 working conditions (i.e., pipeline parameters, fluid parameters, pressure parameters, electrical parameters, actuation method, and special requirements).

PARKER Solenoid Valve Selection Criteria:

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

1) Determine the nominal diameter (DN) according to the on-site pipeline inner diameter or flow requirements;

2) Connection method: 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; for low working pressure differentials 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 are preferred for ease of use.

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 continuously energized type cannot be selected; a type that can be continuously energized should be chosen.

6. Selection of Auxiliary Functions Based on Environmental Requirements: Explosion-proof, Check Valve, Manual Operation, Water-resistant (fogproof), Water Spray, Submersible.

D1VW/D1VW*EE Series Directional Control Valve

The D1VW is a directional control valve with an NG06 (CETOP 03) mounting specification, capable of high-limit flow switching performance with very small pressure drops. Soft-switching or solenoid options meeting ATEX and IECEx certifications are available.

The D1VW is a directional control valve with an NG06 (CETOP 03 / NFPA D03) mounting specification. Due to its optimized flow path design, it achieves a flow rate of up to 80 l/min with a very small pressure drop. The maximum operating pressure is 350 bar.

A variety of valve core options are available, allowing for configuration with various hydraulic circuits. A soft-switching valve is available for smooth switching. An additional damping orifice on the solenoid valve switching channel extends the switching time.

The D1VW*EE is an ATEX-certified version of the D1VW series valve. This valve not only complies with ATEX certification (explosion protection rating Ex e mb II T4 Gb for Zones 1 and 2) but is also compatible with IECEx standards (equipment class 2 G). All certified solenoids are DC coils. Valves for AC use include a rectifier.

PARKER Solenoid Valve Performance Requirements

1. Reversing Performance

1. **Reliable Switching and Reset Time:** Under specified operating conditions, can the solenoid valve reliably switch directions after energization and reliably reset after de-energization?

2. **Pressure Loss:** The pressure loss of a solenoid directional valve consists of flow loss and throttling loss caused by fluid flowing 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. **Switching and Reset Time:** The time required from energizing the electromagnet to the termination of valve spool switching. Reset time refers to the time required from de-energizing the electromagnet to the valve spool returning to its initial position.

5. **Switching Frequency:** The maximum number of switching operations allowed per unit time.

6. **Service Life:** The service life of a PARKER solenoid valve is determined by the failure of major components, resulting in the inability to perform normal switching and reset actions, or by the significant deterioration of its main performance indicators exceeding the specified number of switching operations.

A PARKER solenoid valve consists of an electromagnetic coil and a magnetic core, and has a valve body containing one or more orifices. When the coil is energized or de-energized, the rotation of the magnetic core causes fluid to flow through the valve body or be cut off, thus changing the direction of the fluid. The electromagnetic components of a solenoid valve consist of a fixed iron core, a moving iron core, and a coil; the valve body consists of a spool, a sleeve, and a spring base. The solenoid coil is directly mounted on the valve body, which is enclosed in a sealing tube, forming a simple and compact assembly. Commonly used solenoid valves in production include 2-position 3-way, 2-position 4-way, and 2-position 5-way valves. Here, we'll first explain the meaning of "2-position": for a solenoid valve, it means energized and de-energized; for the valve it controls, it means open and closed.

A malfunction of the solenoid valve will directly affect the operation of switching and regulating valves. Common malfunctions include the solenoid valve not operating. The following troubleshooting steps should be taken:

1. Loose or disconnected solenoid valve wiring. The solenoid valve will not be energized. Tighten the wiring.

2. Burned-out solenoid valve coil. Disconnect the solenoid valve wiring and use a multimeter to measure. If an open circuit is detected, the solenoid valve coil is burnt out. The causes include: Moisture in the coil leading to poor insulation and magnetic leakage, resulting in excessive current and burnout. Therefore, it's crucial to prevent rainwater from entering the solenoid valve. Additionally, an overly stiff spring, excessive reaction force, or too few coil turns resulting in insufficient suction can also cause coil burnout. In an emergency, the manual button on the coil can be switched from the normal "0" position to the "1" position to open the valve.

3. Solenoid valve jamming: The clearance between the solenoid valve's spool sleeve and valve core is very small (less than 0.008mm), and they are usually assembled as a single piece. When mechanical impurities are introduced or there is insufficient lubricating oil, jamming can easily occur. A possible solution is to insert a steel wire through the small hole at the head to spring it back. The fundamental solution is to disassemble the solenoid valve, remove the valve core and valve core sleeve, and clean them with CCI4 to ensure the valve core moves freely within the valve sleeve. During disassembly, pay attention to the assembly sequence of each component and the location of external wiring to ensure correct reassembly and wiring. Also check if the oil mist lubricator nozzle is blocked and if there is sufficient lubricating oil.
