Quick coupling / shut-off connector SU R3/4" with drain valve, for expansion vessel 7613000

Quick connector for expansion vessel – safety and installation convenience

This quick connector / shut-off coupling SU R3/4” with a drain valve, designed for mounting with expansion vessels, is a key element of every heating and cooling installation. It allows for safe isolation of the medium during maintenance, repairs or dismantling of the expansion tank, minimizing the risk of uncontrolled fluid leakage. The drain valve allows for effective removal of residual medium from the installation, which is particularly important before starting service work.

The connector made of brass is characterized by high corrosion resistance and long-term reliability. It is fully compatible with the PN-EN 12828 standard, which guarantees its safety and compliance with applicable regulations. Designed to operate at a pressure of PN 10 and a temperature of up to 120°C.

Practical benefits for the installer and user:

• Safety: Provides safe isolation of the installation during servicing of expansion vessels, eliminating the risk of flooding or damage to system components.
• Convenient installation and dismantling: Allows for quick and easy removal of the expansion vessel without the need to drain the entire installation.
• Installation draining: The drain valve facilitates the removal of residual medium from the installation before starting service or maintenance work.
• Durability: Brass construction provides corrosion resistance and long-term reliability in harsh operating conditions.
• Compliance with standards: Meets the requirements of PN-EN 12828, guaranteeing the safety and proper functioning of the system.
• Versatility: Designed for use in heating, cooling and solar installations.

The SU R3/4” connector is an ideal solution for both professional installers and end-users looking for a reliable and easy-to-use element to protect their heating or cooling system. Thanks to it, service work becomes safer, faster and more efficient. In addition, the ability to drain the installation before dismantling expansion tanks minimizes the risk of damage and ensures cleanliness in the workplace.
