Accessories of AVK Gate valve
AVK offers a wide range of valve accessories including extension spindles, surface boxes, handwheels, stem caps and t-keys.
Extension spindles
AVK's extension is available in two designs including fixed length and telescopic extension spindles for both gate valve and service connection valve.
- Fixed length extension spindles are used when the distance between the valve and the ground surface is known so that only minor adjustment after installation is needed. The patented AVK fixed design facilitates fast and easy shortening of the extension spindle by use of a hacksaw.
- Telescopic extension spindles are used when the distance between the valve and the ground surface can vary, and adjustment of the extension spindle may be required after installation. AVK telescopic extension spindles are designed with ears that can be fixed into AVK surface boxes and a lock spring that prevents the telescopic part from collapsing during installation.
Surface boxes
AVK offers different other designs in both ductile iron and synthetic materials, as well as support tiles for increased support surface in weak soils.
- The floating surface boxes with internal fixation of telescopic extension spindles enable height adjustment after installation.
- The Classic range comprises both fixed and height adjustable synthetic surface boxes, all DVGW approved and withstanding traffic loads according to DIN 1072.
