Horizontal Flanged Check Valve - Series M6 Stainless Steel with Spring - DN 100; L=23.5mm BRA.M6.623 PR

Product detailed description

Horizontal flanged check valves are essential components in systems where unidirectional flow is required to prevent backflow. These valves are commonly installed in HVAC (heating, ventilation, and air conditioning) systems, water distribution networks, and industrial applications involving compressed air, oils, and hydrocarbons. Installers and technicians working in commercial and industrial buildings often use these valves to ensure system integrity and prevent damage from reverse flow. The valve is designed for installation between flanges and is compatible with a range of system pressures and temperatures.

Proper selection and installation are critical to ensure the valve functions correctly and maintains system efficiency. The valve must be sized to match the flow rate and pressure conditions of the system, and its materials must be compatible with the media being transported. The spring-loaded closure ensures reliable sealing even under low backpressure conditions, making it suitable for a wide range of applications.

Technical parameters

Installation and connection

This valve is installed between two flanges and requires proper alignment to ensure a secure and leak-free connection. The flange dimensions must match the PN rating (PN 6) specified in STN EN 1092-1. The installer should verify that the flange surfaces are clean and free of debris before tightening the bolts. Common installation mistakes include misalignment of the flanges, over-tightening of the bolts, and failure to check the sealing surfaces. These errors can lead to leaks or premature failure of the valve.

Compatibility and accessories

This valve is compatible with a range of flanged piping systems and is suitable for use with water, glycol solutions, oils, and hydrocarbons. It is not recommended for steam applications. When installing this valve, it is important to ensure that the flanges and gaskets used are compatible with the system pressure and temperature. No additional accessories are required for standard installation. The valve can be integrated into larger systems alongside other flanged components such as pumps, filters, and control valves.

Technical background for designers

The valve operates on a simple principle: the spring-loaded disc allows flow in one direction and closes to prevent backflow. The PTFE sealing material ensures a tight closure and reduces friction during operation. The valve's performance is influenced by factors such as the media viscosity, temperature, and pressure. Designers should consider these factors when selecting the valve for a specific application to ensure optimal performance and longevity.

Service and operation

Regular inspection of the valve is recommended to ensure it remains in good working condition. The installer should check for signs of wear, corrosion, or leakage around the flange connections. The spring and sealing surfaces should also be inspected for damage or deformation. If the valve shows signs of failure, it should be replaced immediately to prevent system downtime. No specific service intervals are provided in the technical data, but routine checks are advised as part of standard maintenance procedures.

Frequently asked questions

Can this valve be used with glycol solutions?
Yes, the valve is suitable for use with water containing up to 50% glycol content. The materials used in its construction are compatible with this type of media.

Is this valve suitable for steam applications?
No, the valve is not recommended for use with steam. The technical data explicitly states that it is not suitable for this type of media.

What is the minimum backpressure required for the valve to close?
The valve requires a minimum backpressure of 0.3 bar to ensure the disc closes properly and prevents reverse flow.

Can this valve be installed in a vertical orientation?
No, the valve is designed for horizontal installation only. Installing it vertically may affect its performance and sealing capability.
