Diaphragm valve WL2862

electrically-actuatedmanualflow control

Product Overview
A urinal flush valve designed for commercial and public restroom systems to control flushing cycles, reduce water consumption and provide reliable performance across variable inlet pressures. Available in manual, sensor-operated and solenoid-controlled versions, the WL2862 is engineered for longevity and easy maintenance.

Main Features

• Controlled flush volume for water savings.
• Fast response: on ≤ 0.15 ms, off ≤ 0.5 ms.
• Low-noise operation suitable for high-traffic environments.
• Corrosion-resistant materials: stainless threads, POM components, brass solenoid housing.
• Leak-tight sealing and simple serviceability (filters, diaphragms replaceable).
• Available modes: manual, sensor (automatic), solenoid.

Advantages & Disadvantages (summary)

• Advantages: consistent flush performance, improved hygiene with sensor models, water savings, configurable settings, robust for commercial use.
• Disadvantages: higher initial cost for automatic/sensor variants, periodic maintenance required, dependence on power or batteries for sensors, misconfiguration may cause over-flushing.

Troubleshooting (common issues & remedies)

• No water flow: check supply valve, inlet filter and system pressure.
• Continuous flow: inspect and replace diaphragm/seal, clean internal debris, test/replace solenoid if needed.
• Weak flush: increase supply pressure if possible, adjust flow regulator, check piping for clogs.
• Leaks: tighten fittings, replace O-rings or damaged parts, replace valve body if cracked.
• Sensor faults: verify power/batteries, clean sensor lens, replace sensor module if defective.
• Loud operation: check pressure regulator, secure internal components.
