Features/Benefits
- Epoxy lined and prime exterior
finished carbon steel pressure vessels. Non-ASME construction with 100
psig working pressure.
- Galvanized steel face-piping
assembly with cast iron, normally-open, "Y" pattern diaphragm
control valves. Filters
with service piping 6" and larger utilize flanged carbon steel
face-piping and double-acting butterfly control valves.
- Pilot stager valve controller
for automatic backwash operation. Pre-wired in a NEMA-12 enclosure with
an adjustable timeclock for backwash initiation.
- Self-adjusting flow control
to maintain accurate backwash rates.
- PVC media-retaining underdrain
distribution system in either hub-radial or header-lateral configurations
for minimal pressure drop and proper backwashing.
