Double Spade Valve (DSV)

altimg
 The Hy-Ram DSV totally revolutionises the method for making Branch Connections to existing Water Mains. For the first time ever – new works can be connected, pressure tested and 100% chlorinated by alleviating the need to ‘break-down’ in order to remove the spade or temporary fittings.Traditionally the new main is sterilised and then once again exposed to the environment to remove the spade and temporary fittings to allow ‘piping up’ the supply line to the distribution line. This method is flawed in that it leads to a substantial risk of chemical and bacteriological contamination. It is precisely this risk that the regulations governing the procedure are intended to eliminate!
 Designed as a ‘one-use only’ installation, the utilisation of the DSV mitigates any risk of contamination and provides a safe, efficient and easy method of making a branch connection. Whereas traditional methods require two lengthy separate visits to site to carry out pipe fitting operations – the DSV only requires the initial setting up and then the secondary visit just involves removing the blades and blanking off… the cost savings are significant!

The Benefits

  • Double spade design to ensure separation between supply and distribution lines
  • Alleviates the requirement to ‘break down’ mitigating the risk of chemical and bacteriological contamination
  • ‘One Hit’ new mains connector requiring only a single visit to site to carry out pipe fitting operations
  • No more ‘Hydrant to Hydrant’ or other temporary works required
  • Built in flushing, chlorination and pressure testing facilities
  • Minimal maintenance requirements due to no moving parts
  • By-pass arrangement facilitates controlled filling of distribution line and potential for future DMA flow rate monitoring to check leakage
