Flanged Flow-Adjustment Valves
Also known as butterfly valves, these bolt to flanges for adjusting and regulating flow in flanged pipelines.
Wafer valves must be sandwiched between two flanges; they have tabs or unthreaded holes to help align the valve between the flanges.
Lockable lever handles can be fixed in place with a padlock (not included).
Wheel handles open and close with multiple turns, providing fully adjustable flow.
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.

Extended-Life Flanged Flow-Adjustment Valves
- Valve Type: Butterfly
- For Use With: Water, Air, Argon, Helium, Krypton, Neon, Steam, Xenon
- Specifications Met: API 609, ASME B16.34, ASME B16.5, MSS-SP-25, MSS-SP-61, MSS-SP-68
For a longer service life than other flanged flow-adjustment valves, these are designed to open and close with minimal wear on internal components. They 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 grooves to help align the valve between the flanges.
316 stainless steel valves are more corrosion resistant than carbon steel valves.
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
- 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.

Flanged Flow-Adjustment Valves for Chemicals
With seats that can stand up to aggressive and corrosive solutions, these valves are often used in chemical-processing applications. They bolt to flanges for adjusting and regulating flow in flanged pipelines.
Wafer valves must be sandwiched between two flanges; they have tabs or unthreaded holes to help align the valve between the flanges.
Lockable lever handles have 10 flow-adjustment positions. The handle can be fixed in place with a padlock (not included).
Wheel handles open and close with multiple turns, providing fully adjustable flow.
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.

Flange-Mount Check Valves
- For Use With: Air, Argon, Helium, Krypton, Neon, Water, Xenon
- Disc Material: Bronze
- Seal Material: Buna-N Rubber
Sandwich these valves between two ANSI flanges for backflow prevention at a fraction of the weight of flanged check valves and a reduced pipeline footprint. ANSI flanges are sold separately. All valves open to allow flow in one direction and close when flow stops or reverses.
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.

High-Flow Flanged Air-Driven On/Off Valves
- Valve Type: Ball
- For Use With: Oil, Air, Natural Gas, Propane, Butane, Argon, Diesel Fuel, Ethylene Glycol, Fuel Oil, Gasoline, Helium, Kerosene, Neon, Steam, Xenon, Krypton
- Seal Material : PTFE Plastic
- Specifications Met: ASME B16.34
Their ball-valve design allows these valves to handle three times the flow of other flanged valves. They operate on compressed air to automatically start and stop flow faster actuation than motor-driven valves. You must control the air to the actuator using either the included electric pilot valve or a manual on/off valve (not included). These valves don’t require a minimum pressure drop between the inlet and outlet for operation. All are full port, so they do not restrict flow.
The actuator is secured to the valve body with a bracket for easy disassembly, maintenance, and repair. A visual flow indicator on the top of the actuator shows whether the valve is open or closed. The manual override allows you to operate the valve during power outages.
Single-acting actuators only require air pressure to open the valve; they automatically spring closed when the air turns off. These valves are normally closed unless actuated. Double-acting actuators require air pressure to open and close the valve. Once actuated, these valves remain actuated until air pressure is applied to close them, so they do not have a valve starting position.
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.
