Plast-O-Matic Valves Introduces 4-Inch RVDT

Harrington Industrial Plastics - Plast-O-Matic

Big Pipe Size with a Super Low Profile

The industry’s most versatile relief/bypass/backpressure and anti-siphon valve has broadened its application base even further, with the exciting addition of 4″ pipe sizes!

They may look different from the usual RVDT, but they have the same identical quality features and performance…

  • PTFE diaphragm with no wetted elastomers
  • Pressure/Relief settings from 5 to 100 PSI
  • High capacity flow path for maximum flow volume
  • Individually tested prior to shipment and sold with our standard True Blue Three Year Guarantee.
  • Patented Fail-Dry® early warning vent

…Most importantly, a new non-rising stem design keeps the overall height under 16″! 

4″ sizes in PVC and CPVC are available from stock but in limited quantities; lead times may vary for orders due to the complexities and time required for its custom fabrication process.
