DIMENSIONING OF MANHOLES Most HYDROVEX ® models may be installed in a standard 36-inch diameter manhole. All models may also be installed in a rectangular manhole with a minimum dimension of 36 inches (24 inch diameter or rectangular manhole may be used for smaller models). NOTE that in the case of a square manhole, the outlet flow pipe must be centered on the wall to ensure enough clearance for the unit. A minimum clearance "H" should be established between the floor of the manhole and the invert of the outlet pipe to install the regulator. Figure 4 gives the various dimensions required for a given regulator. HOW TO SPECIFY THE TYPE OF HYDROVEX ® REGULATOR In order to specify a HYDROVEX ® regulator, the following parameters must be defined: • The model number (ex: 100-VHV-1) • The diameter and type of outlet pipe (ex: 6" diam. SDR 35 or 8" diam. RCP) • The desired discharge (ex: 50 l/s or 1.76 CFS) • The upstream head (ex: 2 m or 6.56 ft.) * • The manhole diameter (ex: 36" diam.) • The minimum clearance "H" (ex: 10 inches) • The material type (ex: 304 s/s, 11 Ga. standard) PLEASE NOTE THAT WHEN REQUESTING A PROPOSAL, WE SIMPLY REQUIRE THAT YOU PROVIDE US WITH THE FOLLOWING: project design flow rate pressure head chamber’s outlet pipe diameter NOTE: Upstream head is defined as the difference in elevation between the maximum upstream water level and the invert of the outlet pipe where the HYDROVEX ® flow regulator is to be installed.
