Lightweight Flanged Flow-Adjustment Valves
For Four Bolt Holes
For Eight Bolt Holes
- Valve Type: Butterfly
- For Use With: See table
An aluminum body provides strength and durability at half the weight of other metal flanged flow-adjustment valves. These valves bolt to flanges for adjusting and regulating flow in flanged pipelines. Fix the lockable lever handle in place using a padlock (not included) with a shackle diameter up to 5/16”. Valves are wafer style, so they must be sandwiched between two flanges; all have unthreaded holes or tabs to help align the valve between the flanges.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.
