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.

IP67 and NEMA 4X rated switches seal out water from temporary submersion and have increased protection against corrosion, similar to 304 stainless steel.

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.

Designed for use in areas where flammable substances are present, these switches are CSA certified for hazardous locations. Mount them through a tank wall.

Style A meets Class I, Divisions 1 and 2, Groups A, B, C, and D; Class II, Divisions 1 and 2, Groups E, F, and G; and Class III, Divisions 1 and 2.

UL listed for use where flammable gases or combustible dusts may be present, these flow switches activate or deactivate equipment when your flow rate reaches a set point. Use the adjustment screw to select their set point. They actuate when your flowing liquid or gas pushes their paddle into a certain position determined by the set point. All are single pole, double throw (SPDT) and can either turn one device from off to on (normally open) or on to off (normally closed). Mount them horizontally. Rated NEMA 4, they also protect against weather and washdowns.

These flow switches are calibrated with water and air. You can use them with other liquids and gases, but they may not measure accurately if the viscosity is different from water or air.

Safe to use where flammable gases and combustible dust may be present, these switches activate or deactivate when your flow reaches a factory-set level. All are UL listed for hazardous environments. Because their set point is fixed, they’re ready to go, making them easy to install. They actuate when your flowing liquid or gas pushes their paddle into a set position. These switches are single pole, double throw (SPDT) and can turn one device from off to on (normally open) or from on to off (normally closed). They must be mounted horizontally to function accurately.

These switches are calibrated with water and air. They can also be used with other liquids and gases but may not measure accurately if their viscosity is significantly different.

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 F 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.

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.
