These valves are rated for environments where hazardous material is present. Often used to extend and then retract a cylinder at different speeds, they create two actions and have two exhaust ports, which allows you to control the speed of each action by attaching a flow control valve to each exhaust port. They direct airflow from the inlet to your equipment and exhaust return airflow to create motion. Apply voltage to the electrical connection to actuate. Return actuation is by spring, so they go back to their original position when voltage is removed. Also known as 4-way valves.

5/3 (closed center) valves close all ports in the off position to stop equipment in a locked position with air pressure holding it in place.

Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve.

Hazardous location environmental ratings indicate whether manufacturers have included safety features in products to facilitate their safe use in a hazardous environment. Before selecting a product for a hazardous location, ensure it is rated for your environment.

Built with an explosionproof enclosure to meet NEMA 7 and 9 standards for hazardous locations, these switches were tested and verified by UL and CSA for use where explosive liquids, dust, and gas are present. When they reach the set pressure, they power equipment, signal controls, or trigger alarms. They’re single pole, double throw (SPDT) and can be installed to turn one circuit from off to on (normally open) or from on to off (normally closed). In addition to being UL listed and CSA certified, these switches are CE marked, so they also meet European safety standards.

All switches are IP and NEMA rated for use outdoors and protection from some corrosion, dust, and spraying water.

Designed for use in areas where flammable substances are present, these switches are CSA certified for hazardous locations. Mount them through a tank wall. All are rated NEMA 4 for protection from washdowns. All are single pole, double throw (SPDT) and can be installed to turn one circuit from “off” to “on” (normally open) or from “on” to “off” (normally closed).

Switches with stainless steel body are more corrosion resistant than switches with brass body.

These switches are UL listed for environments with flammable gases and combustible dust. They activate or deactivate equipment when the flow rate reaches your set point. All are single pole, double throw (SPDT) and can be installed to turn one circuit from “off” to “on” (normally open) or from “on” to “off” (normally closed).

Switches with a 304 stainless steel body are more corrosion resistant than switches with a brass body and meet NEC Class I, Divisions 1 and 2, Groups A, B, C, and D; and NEC Class II, Divisions 1 and 2, Groups E, F, and G.

For applications with a variable flow rate in environments with flammable gases and combustible dust, these UL-listed switches have an adjustment screw to alter the set point. They activate or deactivate equipment when the flow rate reaches your set point. All are single pole, double throw (SPDT) and can be installed to turn one circuit from “off” to “on” (normally open) or from “on” to “off” (normally closed).

Switch with a 304 stainless steel body is more corrosion resistant than the switch with a brass body. It meets NEC Class I, Divisions 1 and 2, Groups A, B, C, and D; and NEC Class II, Divisions 1 and 2, Groups E, F, and G.

Rated for use in environments where hazardous material is present. These flashlights have built-in LEDs that last longer, are more efficient, and generate less heat than other light technologies.

Flashlights with a bull’s eye beam have a bright center for long-distance illumination.

Style G can operate on either the included rechargeable batteries or standard AA alkaline batteries.

Flashlights that cannot be sold to the regions listed are restricted by local energy efficiency regulations.

Hazardous location environmental ratings indicate where manufacturers have included safety features in products to facilitate their safe use in hazardous environments. Before selecting a product for a hazardous location, ensure it is rated for your environment. See About Hazardous Location Environmental Ratings.

Note: Battery life is significantly reduced when flashlights are used at the high-beam light setting.

Small enough to keep in your shirt pocket, this penlight is rated for use in environments where hazardous material is present. It’s also rated IP04 to withstand liquid splashed from all angles. It has a long-lasting, built-in LED that’s more efficient and generates less heat than other light technologies. This penlight casts a bull’s eye beam that has a bright center for long-distance illumination. It has a knurled body for a slip-resistant grip.
