FAQ
For which pipelines are the design and connection of the EBRO CK butterfly valve suitable?
The EBRO CK is a centre-line wafer butterfly valve with a body designed for clamp connections. Its internally spherically machined contour and smooth continuous seal ring make it ideal for clamp-connected pipelines requiring easy removal and fast maintenance.
What are the applicable sizes, pressure and temperature ranges of the CK butterfly valve?
The nominal size range is DN 80 to DN 250, and the maximum operating pressure is 1 bar. The operating temperature range is -10°C to +60°C; the actually permissible temperature must be confirmed in combination with the medium and the operating pressure.
What sealing standards does the CK butterfly valve comply with?
The CK butterfly valve meets the EN 12266 Leakage rate A requirement and ISO 5208 Category 3. These ratings indicate the valve's shut-off sealing performance under specified test conditions.
What materials are used for the body, disc and stem of the CK butterfly valve?
The body is made of aluminium alloy; the disc seal is white-coated NBR with a hardness of 90° Shore A, stated to be FDA-compliant; the stem is AISI 316 (1.4401). Stem material options are available on request.
Is the CK butterfly valve easy to maintain and to fit with actuators?
The valve is designed for quick and easy removal and features a maintenance-free, low-loss construction. Its top flange complies with EN ISO 5211, allowing the fitting of actuators or manual operators matching that interface standard.
