Flush valve SIAMP OPTIMA 50 universal, dual flush 3/6 L, pull-cable actuation

SIAMP OPTIMA 50 universal flush valve with dual flush 3/6 L is designed for use in cisterns where a compact, water-saving discharge mechanism is required. The unit operates via pull-cable actuation and provides selectable flush volumes of approximately 3 liters for a reduced flush and 6 liters for a full flush. Its construction includes an adjustable sealing system intended to facilitate maintenance and reduce the risk of leaks, making it suitable for a range of residential and commercial toilet installations.

Advantages

The OPTIMA 50 offers dual-flush control that helps reduce water consumption through clearly defined reduced and full flush volumes. Its pull-cable actuation enables flexible installation in cisterns with remote or ceiling-mounted actuators. An adjustable sealing mechanism simplifies commissioning and routine maintenance, while the universal design fits many common cistern geometries, supporting straightforward replacement or retrofit projects.

Suitable for

• Residential toilets requiring a compact dual-flush solution
• Commercial or public restrooms where remote cable actuation is needed
• Retrofit projects replacing older flush valve mechanisms
• Installations prioritizing reduced water consumption and reliable sealing

Key specifications

• Dual flush volumes: 3 L (reduced) and 6 L (full)
• Actuation type: pull-cable operation
• Universal cistern compatibility for compact and standard installations
• Adjustable sealing system for maintenance and leak prevention
• Designed for use with gravity-fed cisterns

How to use

Install the flush valve into the cistern following the manufacturer's installation orientation and connect the pull cable to the external actuator according to the required routing. Adjust the sealing mechanism to ensure watertight closure when the valve is in the rest position, then set the reduced and full flush volumes as needed within the product's adjustment range. Test both actuation positions to confirm reliable operation and check for any leaks around the seal and mounting points before placing the cistern back into regular service.

Usage recommendations

For consistent performance, inspect the sealing surfaces and cable connection periodically and perform adjustments or replacements if you observe dripping or inconsistent flush volumes. Use the reduced 3 L flush for liquid waste to maximize water savings and the 6 L flush for solid waste. When installing in commercial settings, ensure the pull cable path is protected from abrasion and excessive bending to maintain long-term reliability.
