S-Gate Valve
S-Gate Valve is an innovative product where a gate valve can be installed without disrupting supply.
Designed and tested in accordance with Australian Standards, our high-quality valves are made of high-grade ductile iron.
DN80 - DN450 S-Gate Valve Gen II has been appraised by Water Services Association Australia to PN16.
Our Standard Compliance
The Upper component of the S-Gate Valve has been designed and manufactured in accordance with AS/NZS 2638.2 - Gate Valves for Water Works Purposes
The Lower component of the S-Gate Valve has been designed and manufactured in accordance with AS4181 - 2013 - Repair and Offtake Clamps for Water Industry Purposes
CNS Engineering have underwent rigorous development of the S-Gate valve to comply with Australian Standard. As a result, the S-Gate valve was able to comply with relevant Australian Standards.
S-Gate valve has successfully fulfilled the requirement of both standards including but not limited to
AS / NZS2638.2 - Gate Valves for Water Works Purposes
- No leaks or failure observed on the valve gate at ASTP 2000kPa Pressure
AS4181 - 2013 - Repair and Offtake Clamps for Water Industry Purposes
- No leak observed on lower clamp at a pressure of 2400 kPa for a test duration of 120 minutes
Our Unique Cutting Technology
Traditionally, the line stops involved extraction of size x size coupon extraction. However, when the coupons are vertically extracted, often coupons were not able to be retrieved and would be displaced inside the main.
To eliminate this issue, S-Gate valve as adopted a milling technology in lieu of traditional coupon extraction methodology.
As part the drilling process, shavings are released instead of coupon, where the pressure from the existing watermain extracts the metal shavings produced during the S-Gate Valve drilling.
With this technology transition, S-Gate valve removes minimal surface area of the pipe, maintaining the structural integrity.
