Drain Valve Structure
- An electromagnet, valve body, plunger, seal ring, coil housing, terminals, and bracket make up our drain valve, which allows for regulated, leak-free drainage.
- Electromagnet: Produces magnetic force to actuate valve switch and control water flow accurately.
- Valve Body: Guides water flow and houses internal seals for consistent, leak-free operation.
- Coil Housing: Encloses and protects coil from dust, moisture, and mechanical impact.
- Plunger/Piston: Moves under electromagnetic force to open or block water channel.
- Seal Ring: Ensures tight sealing between parts to prevent any water leakage.
- Connector Terminals: Provides electrical connection for receiving signals from the appliance.
- Mounting Bracket: Holds the valve securely in place inside the appliance structure.

FAQ
1.How is the sealing performance of a Drain Valve ensured?
Sealing is achieved using high-quality rubber or silicone rings and precision machining to minimize leakage under different pressures and temperatures during operation.
2.What software tools are used in Drain Valve design?
CAD and simulation tools like SolidWorks or ANSYS are used to model fluid flow, magnetic fields, and stress conditions before manufacturing.
3.How does the Drain Valve meet appliance safety standards?
Designs follow certifications like CE, UL, or RoHS, using flame-retardant materials, proper insulation, and pressure testing to ensure safety and compliance.
4.How is noise reduced in a Drain Valve design?
Noise is minimized through optimized internal geometry, anti-vibration mounts, and smoother flow channels that reduce turbulence and mechanical contact sounds.
5.What testing is done during Drain Valve production?
Each unit undergoes pressure resistance, insulation, leakage, and actuation cycle testing to verify durability, performance, and compliance with quality standards.
6.What type of actuator is commonly used in a Drain Valve?
Most drain valves use solenoid actuators, which rely on electromagnetic force to drive the internal plunger or diaphragm for quick and accurate operation.
