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.

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.

The most chemical-resistant threaded valves we offer, these have a PTFE seal and an alloy body that can withstand extremely aggressive and corrosive chemicals, such as methyl ethyl ketone and toluene. They are standard port, so they slightly restrict flow.

Monel valves are more corrosion resistant than Alloy 20 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.

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.

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.

For applications sensitive to contamination, these valves stop flow without contacting the process media by pressing down on the outside of tubing. They operate on electricity to automatically start and stop flow.

These valves are normally closed unless actuated. They 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. Valves meet IP65 for resistance to low-pressure jets of water and dust.

For high-flow chemical-processing applications, these valves have a ball-valve design that provides at least three times the flow of standard flanged valves. They have a 316 stainless steel body and a PTFE seal that can stand up to aggressive and corrosive solutions. Valves 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 normally open unless actuated. 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. The manual override allows you to operate the valve during power outages.

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.

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.

Perform valve maintenance without unthreading pipe connections. These valves have a three-piece bolted body that comes apart for inline access to internal components. The fluoroelastomer seal and glass-filled polypropylene body can withstand aggressive and corrosive solutions for diverting flow between ports in chemical-processing applications. Valves are full port, so they do not restrict flow.

Valves with a center-port inlet direct flow to either side port. They cannot shut off flow.

Valves with a bottom-port inlet direct flow to either side port or shut off flow completely.

T-handles resist accidental movement when snagged or bumped.

A plastic body withstands pH neutralizing, cleaning, and plating solutions containing sodium hydroxide, methyl ethyl ketone, and other harsh chemicals. Also known as vacuum breakers, these valves have vents that open when pressure drops to relieve vacuum conditions and prevent backward suction from drawing liquid into upstream piping.
