Also known as wafer ball valves, these combine the slim body of a butterfly valve with the high flow rates of a flanged ball valve. All have a 316 stainless steel body for excellent corrosion resistance. They are full port, so they do not restrict 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.

Attach these valves to industry-standard two-bolt flanges on circulation pumps from manufacturers such as Bell and Gossett, Taco, Grundfos, and Armstrong. They have a T-handle that resists accidental movement when snagged or bumped. All are full port, so they do not restrict flow.

Bolt these valves to ANSI flanges. A glass-filled vinyl ester body and a PTFE seal withstand aggressive and corrosive solutions in chemical-processing applications. Fix the lockable lever handle in place using a padlock (not included) with a shackle diameter up to 5/16”. All are standard port, so they slightly restrict flow.

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.

A 316 stainless steel body and a PTFE seal stand up to aggressive and corrosive solutions in chemical-processing applications. Their ball-valve design allows these valves to handle at least three times the flow of standard flanged valves. For faster actuation than motor-driven valves, they 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). These valves automatically start and stop flow and don't require a minimum pressure drop between the inlet and outlet for operation.

Their ball-valve design allows these valves to handle at least three times the flow of standard flanged valves. All operate on electricity to automatically start and stop flow. They don’t require a minimum pressure drop between the inlet and outlet for operation. All are fail in place; upon loss of power, the valve will remain in its current position. Valves 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. 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. A manual override allows you to operate the valve during power outages.

Bolt these valves to flanges to divert flow between ports in flanged pipelines. Any port can be used as an inlet or an outlet. Turn the handle to direct flow from the inlet port to either outlet port. Valves cannot shut off flow.

316 stainless steel valves are more corrosion resistant than carbon steel valves.

Full-port valves do not restrict flow.

Standard-port valves slightly restrict flow.

Automatically divert flow between ports in flanged pipelines with these valves that operate on compressed air for faster actuation than motor-driven valves. You must control the air to the actuator using either an electric pilot valve (sold separately) or a manual on/off valve (not included). Valves do not require a minimum pressure drop between the inlet and outlet for operation. Valves are standard port, so they slightly 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 which direction flow is being diverted.

Air-to-divert/air-to-return valves require air pressure to divert flow to the right-port outlet and air pressure to return flow to the left-port outlet.

Air-to-divert/spring-return valves require air pressure to divert flow to the right-port outlet. They automatically return flow to the left-port outlet when the air turns off to ensure the valve only diverts flow to the right port when air is on.
