Materials Selection

  • Left Pipe (300mm): Hydra-Stop "Insta-Valve 250" with 304 stainless steel body insertion sleeve.

  • Right Pipe (600mm): AVT "EZ Valve" with epoxy resin coated ductile iron body. 

Key Points

  • These valve insertions allowed for new in-line valves to be installed with no disruption of service to the hot tapped pipe. 

  • Both of these valve insertion assemblies had been carefully pressure tested to assure a high-quality, leak free installation.

  • The stainless steel body of the Insta-Valve and durable coating on the EZ Valve help ensure a product life equal to that of the host pipe.
