Non-return valve, check valve, flanged, DN 150, PN16, lead-free, class EA RV283S-150A

Non-return valve, anti-pollution, flanged, with a nominal diameter of DN 150 and a nominal pressure of PN16, manufactured in lead-free technology (Pb-free), classified as EA according to PN-EN 1717. The product is designed to protect water supply systems from backflow, both in internal installations (e.g., behind water meters) and in transmission networks of drinking water.

This type of valve is widely used in residential, industrial and commercial buildings, wherever protection of the water supply installation against back contamination or undesirable backflow is required. Thanks to its versatility and reliability, it performs well in various operating conditions.

Construction and materials:

The RV283S valve is characterized by a solid construction. The body is made of gray cast iron with an internal and external powder coating, which ensures high corrosion resistance and durability. Internal elements, such as the valve disc, spring and seals, are made of stainless steel and EPDM, guaranteeing long-term tightness and no impact on the quality of drinking water. The replaceable disc, spring and seal design facilitates servicing and extends the life of the device.

Advantages and benefits:

• Drinking water safety: The lead content in all materials is less than 0.1%, which meets the stringent standards for health protection.
• Versatility: Can be used in various types of installations – domestic, industrial or public utility.
• Durability: The use of high-quality materials and powder coating ensures corrosion resistance and long-term operation.
• Low pressure drop: The valve design minimizes flow resistance, which translates into efficient operation of the installation.
• Easy servicing: Replaceable elements facilitate maintenance and repairs.
• No water hammer: The valve design eliminates the risk of undesirable water hammer in the installation.
• Compliance with standards: Meets the technical requirements of PN-EN 1717 and has approvals from DVGW, KIWA and BELGAQUA.

The valve has a PZH hygiene certificate confirming its safety for human health and compliance with applicable sanitary regulations. The manufacturer's warranty is 5 years from the date of manufacture.
