Flanged Air-Driven On/Off Valves
- Valve Type: Butterfly
- For Use With: Water, Air, Argon, Helium, Neon, Steam, Xenon, Krypton, Drinking Water
- Seal Material : EPDM Rubber
- Specifications Met: API 609, NSF/ANSI 61
To automatically start and stop flow faster than motor-driven valves, these operate on compressed air. You must control the air to the actuator using either the included electric pilot valve or a manual on/off valve (not included). Valves don’t require a minimum pressure drop between the inlet and outlet for operation.
The actuator is directly mounted to the valve body to minimize movement and reduce wear. 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. Valves meet NSF/ANSI 61 for use with drinking water.
All valves are lug style; their hole pattern matches ANSI flanges of the same pipe size. They can be sandwiched between two flanges, or bolt them directly to a single flange for servicing one end of the pipeline without depressurizing the other side.
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, 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.

Flanged Motor-Driven On/Off Valves
- Valve Type: Butterfly

- Seal Material: EPDM Rubber
- Specifications Met: API 609, NSF/ANSI 61
Automatically start and stop flow in flanged pipelines with these valves that operate on electricity. All are fail in place; upon loss of power, the valve will remain in its current position.
The actuator is directly mounted to the valve body to minimize movement and reduce wear. A visual flow indicator on the top of the actuator shows whether the valve is open or closed. Two single pole, double throw (SPDT) auxiliary switches allow you to connect these valves to temperature-monitoring equipment, programmable logic controllers, or conveyor sirens. The internal heater automatically turns on when the valve is actuated to prevent motor damage caused by condensation buildup. Valves meet NSF/ANSI Standard 61 for use with drinking water.
All valves are lug style; their hole pattern matches ANSI flanges of the same pipe size. They can be sandwiched between two flanges, or bolt them directly to a single flange for servicing one end of the pipeline without depressurizing the other side.
Valves with a manual override can be operated during power outages.
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.

- 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.

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.
Lug valves 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.
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.

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.
