About product
The Marine Type U Double Flange Soft Sleeve Butterfly Valve is designed to operate at two different working pressures: PN10 (Pressure Nominal 10 bar) and PN16 (Pressure Nominal 16 bar). The valve undergoes testing to ensure its reliability. During the testing process, the valve’s shell is subjected to a pressure that is 1.5 times the rated pressure, while the seat is tested at a pressure that is 1.1 times the rated pressure.
The flanged valve is suitable for a wide range of temperatures, depending on the type of sleeve used. If the valve is equipped with an NBR (Nitrile Butadiene Rubber) sleeve, it can operate within a temperature range of -10°C to 80°C. However, if it is fitted with an EPDM (Ethylene Propylene Diene Monomer) sleeve, it can withstand temperatures from -10°C to 120°C.
In terms of media compatibility, this flanged butterfly valve is designed to handle various substances. It is suitable for use with water, oil, and gas, making it a versatile option for different applications.
