Polyfast Double Check Valve - 25mm MDPE
The Polyfast Double Check Valve - 25mm MDPE is designed for reliable connections in various piping systems, featuring MDPE x MDPE Polyfast compression fittings. With blue nuts and black bodies, this valve efficiently joins MDPE (both blue and black), LDPE, and HDPE normal and heavy gauge pipes, ensuring versatility in applications.
The valve is constructed from high-quality MDPE material, providing durability and resistance to environmental factors. Accommodating copper and lead pipes, making it a flexible choice for a range of installations.
Complying with UK standards and allowing for use on blue MDPE to BS 6572 and black MDPE to BS 6730. A plastic pipe stiffener (P/N 9922-9926) is required for use with MDPE pipe to maintain a secure connection.
The valve is suitable for applications involving black LDPE to BS 1972: Class C and D, as well as normal gauge black LDPE to IS 134, with the appropriate insert adaptor sets enhancing its versatility. Additionally, adaptor sets are available for connecting copper pipes (to BS 2871 Tables X and Y) and lead pipes (to BS 602, 1085) to polyethylene pipes, further expanding the fitting's compatibility with a variety of piping systems.
The MDPE ends can be easily reduced from 63 mm to 20 mm using reducing sets, and female threads can be bushed down from 2" to 1/2" (a pressure test to 1.5 times the working pressure for a maximum of one hour is required before connecting the installation to the mains supply).
The Polyfast Double Check Valve is an ideal solution for MDPE applications, ensuring secure connections, compatibility with various materials, and adherence to industry standards, making it a reliable choice for both domestic and industrial use.
PLEASE NOTE: The polyethylene pipe systems are not suitable for use as an electrical earth. When using threaded BSP fittings, PTFE tape must be applied to ensure a proper seal.
Alternative Options available.
