Direct-operated solenoid valve WL1854

2-wayfor watercompact

Product Overview
The WL1854 urinal solenoid valve by Weilong Technology is a compact, fast-response solenoid valve designed for sensor-controlled, touch-free flushing systems in commercial and public washrooms. It uses an electromagnetic actuator to control water flow and is compatible with infrared or motion sensors. Materials commonly include brass, stainless steel or reinforced engineering plastics with EPDM or NBR seals. The valve is designed for low power consumption and frequent cycling in high-usage environments such as hospitals, airports, shopping centres and office buildings.

Key Features

• Compact form factor for concealed or space-limited installations
• Fast response (PWM/response ~30 ms reported)
• Low power consumption (0.5–1 W) suitable for battery operation
• Multiple DC voltage options: DC 4.5V / 6V / 12V / 24V
• Waterproof design rated IP65 for washroom environments
• Anti-clogging filter screen to reduce blockage from debris
• Long service life: approx. 200,000 cycles (datasheet)
• Available materials: brass, carbon steel, stainless steel, reinforced plastic; seals EPDM or NBR

Product Presentation / Media
The product is presented as a compact sensor-controlled urinal solenoid valve with demonstration media available (product video and installation illustrations) to assist integration and commissioning.

Applications

• Automated urinal flushing in smart bathrooms
• Public facilities: airports, railway stations, shopping malls
• Commercial buildings: offices, hotels, hospitals, schools
• Battery-powered or low-voltage flushing systems
• Water-saving and building automation projects

Advantages / Disadvantages
Advantages

• Hygienic touch-free operation
• Accurate, metered flushing to conserve water
• Fast acting suitable for immediate flush after use
• Low power draw enables battery-powered installations
• Compact design simplifies retrofit in modern fixtures

Disadvantages

• Requires electrical supply; operation affected during power outages unless battery-backed
• Hard water may affect diaphragm life unless anti-scale measures are used
• Continuous high-pressure or unregulated supply can shorten valve life
• Poor-quality coils or unstable voltage can cause overheating

Notes on Selection and Use
When selecting the WL1854, verify required voltage (DC 4.5/6/12/24V), working pressure compatibility with site supply, required flow rates to meet local regulations, material choice for corrosion resistance, IP rating for the installation, and sensor-control compatibility. For hard-water locations, prefer valves with anti-scale diaphragms and reliable filter screens.
