Direct-operated solenoid valve WL0730

NONCfor water

Overview
A DC latching solenoid valve WL0730 is a bistable valve operated by short polarity-controlled pulses; once switched it holds its state without continuous power. Designed for low-energy, battery or remotely powered systems, WL0730 offers normally open (NO) and normally closed (NC) versions for fluid control of gas, water and compatible media.

Key Features

• Very low power consumption: energy only during switching pulses.
• Compact dimensions for integration in space-constrained equipment.
• Fast and accurate switching with minimal heat generation.
• Reduced thermal stress and extended component life; low maintenance.
• Suitable for battery-powered, IoT and remote applications.
• Reliable operation for liquids and gases with appropriate seals.

Product Overview and Materials
WL0730 is available in NO and NC configurations. Main materials include carbon steel housing, brass and stainless-steel internal parts and engineering plastics. Seals and diaphragms selectable (EPDM, NBR, FKM) to match media compatibility.

Applications

• Industrial automation and control systems
• Water management: smart meters, irrigation, leak detection
• Battery-powered and remote equipment
• Medical portable devices and diagnostics
• Pneumatic and hydraulic control systems
• Appliances and IoT-enabled valves

Maintenance

• Clean valve internals: remove debris, scale; fit upstream filters/strain ers.
• Inspect and replace diaphragms/O-rings when hardened or leaking; choose seal material per fluid.
• Check electrical connections for corrosion, secure wiring and correct polarity.
• Verify pulse parameters: voltage, duration and polarity must meet specifications; incorrect pulses prevent switching or damage coil.
• Inspect magnet and moving parts: ensure free plunger travel and remove corrosion/debris.
• Install and store in dry, clean environments; use rated enclosures outdoors.
• Perform fluid compatibility tests to prevent seal or body degradation.
• Cycle-test valves periodically; include electrical checks in maintenance schedules.
• Recommended inspection: cleaning/inspection every 3–6 months; replace seals based on life or leakage.

Advantages and Disadvantages

• Pros: significant energy savings (no hold current), low heat, bistable reliability and reduced wear.
• Cons: requires pulse/polarity control circuitry, typically higher initial cost, switching depends on magnetic design and correct pulse control.

Manufacturing & Quality Control (Weilong)

• Incoming material inspection: copper wire, magnets, seals, body materials.
• Precision CNC machining and automated coil winding.
• 100% electrical tests: resistance, insulation, pulse response.
• Leak and pressure testing, life-cycle/durability testing.
• Environmental tests: temperature, humidity, corrosion, vibration.
• Control-circuit compatibility checks, ISO-based quality management and final inspection with traceability.
