Rubber Disc Check Valve

ROBO Rubber Disc Check Valve (DCV) is an industrial valve specially designed to prevent backflow in pipeline systems. The product features a robust ductile iron body, an EPDM-coated rubber disc that provides excellent sealing, stable operation, and long service life. With standard BS/DIN/JIS flange connections, ROBO valves are easy to install in water supply and drainage systems, pump stations, fire protection systems (FIRE-FIGHTING), and wastewater treatment applications. This is a reliable choice for projects requiring safety, durability, and long-term performance.

Outstanding Features of the ROBO Rubber Disc Check Valve

ROBO check valves are trusted by many engineers and contractors thanks to their superior advantages:

• Durable construction: The body and cover are cast from ASTM A536 ductile iron, offering excellent pressure resistance and impact protection, ensuring outstanding durability in harsh working environments.
• Tight sealing disc: Coated with elastic EPDM rubber, providing smooth operation, reduced vibration and noise, and minimising water hammer.
• Anti-leak gasket: Equipped with high-quality NBR O-rings for enhanced sealing and reduced leakage.
• Standardised connection: Flange design compatible with international standards (BS4504/DIN/JIS), making installation and replacement quick and easy.
• Easy maintenance: The top-cover structure allows inspection, cleaning, and gasket replacement without removing the valve from the pipeline.
• Clear identification: Products are available with optional blue (B) or red (R) coatings for easy recognition by application.

Practical Applications of ROBO Check Valve

Thanks to its solid design and effective backflow prevention, the ROBO swing check valve is widely used in:

• Urban water supply & drainage systems
• Pump stations and water treatment plants
• Fire Protection (FIRE-FIGHTING): Installed on pump suction/discharge lines to prevent pressure loss and backflow
• HVAC and industrial systems: Suitable for central air-conditioning, wastewater treatment, food & beverage industry, etc.
• Infrastructure & civil projects: Used in water distribution pipelines in residential areas, high-rise buildings, and industrial zones

Economic Benefits for Businesses

Choosing the right valve brings not only technical advantages but also significant economic value:

• Protects equipment & reduces repair costs by preventing backflow that can damage pumps, meters, and auxiliary devices
• Minimises water hammer, extending pipeline lifespan
• Optimises operating costs with smooth operation and minimal leakage
• Easy maintenance, reducing downtime and production losses
• Long-term investment value thanks to durable ductile iron and stainless steel components

Installation Guide for ROBO Swing Check Valve

Installation Steps

1. Prepare the pipeline: Clean flanges and remove debris.
2. Position the valve correctly: Ensure the arrow on the valve body aligns with the flow direction.
3. Align the flanges: Prevent misalignment that may affect disc movement.
4. Install gaskets: Use EPDM or PTFE gaskets as required.
5. Tighten bolts in a crisscross pattern to ensure even pressure distribution.
6. Check operation: Test the valve at low pressure before full operation.

Maintenance Guide

• Inspect the valve every 3–6 months
• Clean the EPDM disc surface to maintain sealing
• Replace NBR O-rings if leakage appears
• Lubricate bolts to prevent corrosion
• Do not exceed PN10/PN16 pressure or temperature limits

With proper installation and maintenance, the ROBO swing check valve will operate reliably and contribute to system efficiency and safety.
