Introducing the

The S-Gate Valve, a pioneering and accredited innovation, offers seamless valve installation at any desired location without disrupting water supply. Specially engineered for potable water systems, this durable and resilient seated gate valve boasts a high-quality ductile iron construction. 

The S-Gate Valve not only provides temporary isolation solutions for water networks but also serves as a permanent installation once in place. Harnessing cutting-edge valve technology, this certified valve ensures an efficient and economical solution for your water system needs.

How the S-Gate Valve works

Traditionally, the line stops involved extraction of size x size coupon extraction. However, when the coupons are vertically extracted, often coupons are not able to be retrieved and would be displaced inside the main.

To eliminate this issue, the S-Gate valve has adopted a milling technology instead of traditional coupon extraction methodology. 

As part of the drilling process, shavings are released instead of coupon, where the pressure from the existing water main extracts the metal shavings produced during the S-Gate Valve drilling. 

With this technology transition, the S-Gate valve removes a minimal surface area of the pipe, maintaining the structural integrity.

Frequently Asked Questions

Is there requirement for water isolation at any point during the installation of S-Gate valve?

No. S-Gate valve can be installed on a live main, without interrupting supply during any stages of installation.

What type of pipes can S-Gate Valve be installed on?

S-Gate Valves can be installed on the following Australia Pipes. DI, CI, AC, PE, MSCL, uPVC and mPVC Pipes

What is the minimum distance between the location of the S-Gate Valve and the cut in location?

Usually, we recommend to keep minimum 9m of undisturbed ground between the isolation point and the cut in location. If this
cannot be achieved, the valve can be strapped in stainless steel and anchored as per the relevant standard. Upon the curing of the
concrete, the distance between the S-Gate valve and the cut in location can be reduced.

How long does the Installation of S-Gate Valve Take?

Under the circumstances that pipe is excavated and exposed, DN100mm to DN200mm will take around 1.5 Hours and DN250mm
~ DN300 will take around 2 Hours. All valves above DN375mm and above will take around 3 Hours excluding excavation works.

What sizes of S-Gate valve are currently available?

Currently, we have DN100, DN150, DN200, DN225, DN250, DN300, DN375 and DN450 S-Gate valve available in Australia

Can S-Gate Valves be anchored.

Yes, S-Gate valves can be anchored using the stainless steel straps. Up to (450mm)

Resources

Fully Compliant with Australian Standards

Our manufacturers have undergone 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 were observed on the valve gate at ASTP 2000kPa Pressure.

AS4181 – 2013 – Repair and Offtake Clamps for Water Industry Purposes

– No leak was observed on the lower clamp at a pressure of 2400 kPa for a test duration of 120 minute.
