Check Valve - DISCONNECTOR - Series ECO 3T - 6/4 inch; L=357mm BRA.ECO 3T

Product detailed description

This check valve is commonly used in industrial and commercial fluid systems where unidirectional flow control is required. It is suitable for applications such as heating, plumbing, and irrigation systems. The device prevents backflow of liquids and ensures system integrity under varying load conditions. It is typically found in closed-loop systems and is compatible with piping configurations requiring reliable sealing and flow regulation.

The ECO 3T model is often integrated into systems where liquid purity and flow direction are critical. It is installed in locations where backflow could damage components or compromise system performance. The device is particularly useful in systems where maintenance and isolation of sections are necessary for serviceability.

Technical parameters

Installation and connection

Installation requires precise alignment of the threaded connections, which are sized from 1/2 inch to 2 inch according to ISO 228-1 standards. The device must be fitted with a filter upstream to prevent clogging and ensure smooth operation. The DISCONNECTOR must also be connected to a drainage system to manage waste fluids. During installation, the direction of flow must be verified to match the design requirements, and all connections should be tightened to the recommended torque to avoid leaks. Common mistakes include incorrect orientation, insufficient filtration, or failure to connect to a drainage system.

Compatibility and accessories

This check valve is compatible with standard piping systems using threaded connections within the specified size range. It is intended to be used in conjunction with a filter to protect against particulate contamination. Additional components such as filters and drainage connections must be ordered separately. The device is not interchangeable with non-threaded or flanged models and is specifically suited for systems that require threaded fittings.

Technical background for designers

The ECO 3T operates using a diaphragm mechanism that opens under forward flow and closes to prevent reverse flow. The body is constructed from brass or bronze, offering durability and resistance to corrosion. The EPDM diaphragm provides flexibility and sealing effectiveness. The valve is designed for integration into closed-loop systems and is suitable for use with fluids in class 4. The service life depends on factors such as fluid composition, temperature fluctuations, and the presence of particulates in the system.

Service and operation

Regular inspection of the filter and drainage system is essential for maintaining operational efficiency. There are no specified service intervals, but periodic checks for wear and leakage are recommended. The device should be isolated from the system during maintenance, and any signs of damage or blockage should be addressed immediately. The diaphragm and internal components should be inspected for deformation or degradation, especially after prolonged exposure to high temperatures or aggressive media.

Frequently asked questions

Can the ECO 3T DISCONNECTOR be connected to a non-threaded system?
No, the model is designed exclusively for threaded connections according to ISO 228-1 standards. Non-threaded systems require alternative fittings or adapters.

Is a filter required before the DISCONNECTOR?
Yes, a filter must be installed upstream to prevent particulate matter from entering the valve and causing blockages or damage to the diaphragm.

Can the ECO 3T handle aggressive media?
The EPDM diaphragm and brass/bronze body offer resistance to many common media, but compatibility with aggressive chemicals must be verified according to the manufacturer's technical data sheet.
