Wafer J9 - stainless steel disc; FKM (Viton) - DN 50; L=43mm BRA.J9.622 FKM

Product detailed description

Wafer-style shut-off valves like the IVAR WAFER J9.622.050 are commonly used in industrial, heating, and ventilation systems where compact and reliable flow control is required. These valves are often installed between flanges in systems handling fluids such as water, oils, and gases. They are particularly suited for environments where space is limited and where frequent maintenance or inspection is not necessary. The valve’s stainless steel construction and FKM sealing material make it suitable for a wide range of media and temperatures, ensuring long-term performance in both residential and commercial applications.

When integrating this valve into a system, it is important to consider the operating conditions, including the type of fluid, pressure levels, and temperature range. The valve is not suitable for steam applications, so alternative designs must be selected for such media. The compact design of the wafer valve allows for easy installation between flanged connections, making it a preferred choice for systems with tight spatial constraints.

Technical parameters

Material	Body and disc - stainless steel AISI 316
Nominal diameter	DN 50
Nominal pressure	PN 16/PN10
Weight	5 kg
Code	J9.622.050
Brand	IVAR

The valve is rated for nominal diameters up to DN 50 and can be used with flanges rated at PN 6, PN 10, or PN 16. The pressure rating must be matched with the flange rating to ensure proper system integrity. The temperature range of -10°C to +150°C must also be considered when selecting the valve for a specific application. The FKM sealing material provides resistance to a range of industrial fluids but is not suitable for steam or high-temperature environments.

Installation and connection

The IVAR WAFER J9.622.050 is designed for installation between two flanges. The valve must be aligned with the flange bolt holes and tightened evenly to prevent misalignment and leakage. The nominal diameter of DN 50 corresponds to the internal flow passage, and the flange connections must be compatible with the PN 16 or PN 10 pressure class. During installation, it is important to ensure that the valve is not over-tightened, as this can damage the sealing material or the valve body. Common installation errors include using incorrect flange ratings or failing to align the valve properly with the flange faces.

Compatibility and accessories

This valve is compatible with standard flanged piping systems that operate within the specified pressure and temperature ranges. It is typically used in conjunction with other valves and fittings that are also rated for the same conditions. No additional accessories are required for standard installation, but it is important to ensure that all components are compatible in terms of material and pressure rating. No related products are listed for this model.

Technical background for designers

The IVAR WAFER J9.622.050 operates as a shut-off valve, allowing or blocking the flow of media through the system. The stainless steel body and disc provide durability and resistance to corrosion, while the FKM sealing material ensures a tight closure. The valve is designed to be installed between two flanges and is not intended for steam applications. The operating temperature range and pressure class must be carefully considered during system design to ensure the valve functions as intended. The compact design allows for integration into systems with limited space, making it suitable for both new installations and retrofitting.

Service and operation

The valve requires minimal maintenance due to its robust construction and reliable sealing mechanism. Regular inspections should be carried out to check for signs of wear or leakage. The FKM sealing material is resistant to a range of industrial fluids but may degrade over time if exposed to incompatible media. No specific service intervals are provided in the technical data, but it is recommended to inspect the valve periodically, especially in high-use or high-pressure applications.
