Gate valves with PE pipe ends for direct welding into PE pipes
AVK's gate valves with PE pipe ends feature a DVGW approved class 1 connection which is stronger than the PE pipe itself. A piece of standard PE pipe is pressed directly onto the grooved valve end. The grooves combined with a sleeve around the valve/pipe connection ensure that the PE pipe material is firmly secured and that the connection remains tight and tensile during the entire service life of the pipeline. The connection is sealed with a shrink hose to provide corrosion protection. The full and straight bore ensures minimum pressure loss and makes under pressure drilling possible. Variants are available for water supply, gas supply and fire protection applications. Furthermore, also with flanged x PE end for water and gas supply, and steel spigot end x PE end for gas supply.
Gate valves with tensile coupling ends for maximum flexibility
AVK also offers tensile couplings with built-in valves, making it easy to turn off the water in case of repair or replacement. The Supa Maxi™ gate valve with tensile universal coupling ends make it possible to install the valve in all types of pipes, and it will often be used to connect an old cast iron pipe with a new PE pipe. The coupling ends are designed with a flexible bracket offering maximum tightness up to PN 16 in all dimensions, and which does not require retightening of the bolts. The valve is very easy to install due to a big insertion depth tolerance, deflection of ± 4° and permanent end protection caps. The Supa Plus™ gate valve is dedicated to PE and uPVC pipes. The compression type gasket allows for a deflection of ± 3.5° and makes it easy to insert the pipe end, even in the large dimensions.
Flanged gate valves to all major standards
AVK offers flanged gate valves to practically all standards, and with face-to-face dimensions according to EN 558 table 2 basic series 14 (short, DIN F4) and series 15 (long, DIN F5) as well as to GOST, SABS, AWWA, AS and BS. Furthermore, we offer gate valves with flange X PE end and flange X spigot end as well as combi-crosses with 3 and 4 outlets. Especially our flanged gate valves are available with several material configurations making them suitable for a wealth of applications within our four segments; water supply, gas supply, wastewater treatment and fire protection.
