Plastic Flanged Flow-Adjustment Valves
- Valve Type: Butterfly
- For Use With: Water, Oil
Often used in low-pressure water pipelines, these valves have a plastic body for the lightest weight of our flanged flow-adjustment valves. Bolt them 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 3/16”. Valves are wafer style, so they must be sandwiched between two flanges. They have unthreaded holes that do not match the ANSI flange pattern; use two of the four holes to 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.

Plastic Flanged Flow-Adjustment Valves for Chemicals
- Valve Type: Butterfly
- For Use With: Water, Carbon Dioxide, Citric Acid, Hydrochloric Acid, Isopropyl Alcohol, Kerosene, Phosphoric Acid, Salt Water
- Seat Material: Fluoroelastomer Rubber
- Specifications Met: FM Approved
In addition to fluoroelastomer seats that resist a wide range of chemicals, these valves have no metal parts to corrode, so they’re often used for chemical-processing applications in corrosive conditions. All 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 7/16”. Valves are wafer style, so they must be sandwiched between two flanges; all have unthreaded holes 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.

Flanged Flow-Adjustment Valves for Drinking Water
- Valve Type: Butterfly
- For Use With: Drinking Water
- Specifications Met: FM Approved, NSF/ANSI 61
These valves meet NSF/ANSI 61 for use with drinking water. They bolt to flanges for adjusting and regulating flow in flanged pipelines. All have seven flow-adjustment positions. The lockable lever handle can be fixed in place using a padlock (not included) with a shackle diameter up to 7/16”. Valves are wafer style, so they must be sandwiched between two flanges; all have unthreaded holes 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.

Flanged Flow-Adjustment Valves for Steam
- Valve Type: Butterfly
- For Use With: Steam
- Seal Material: PTFE Plastic
- Specifications Met: ANSI/ASME B16.34A
Rated for steam pressures up to 100 psi @ 400° F, these valves have PTFE seats for excellent temperature resistance. They bolt to flanges for adjusting and regulating flow in flanged pipelines. These valves are lug style, so they can be sandwiched between two flanges or bolted directly to a single flange for servicing one end of the pipeline without depressurizing the other side. They have threaded flange holes with a hole pattern that matches ANSI flanges of the same pipe size.
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.
