The Versa NAMUR ReBreather:ACTUATOR CONTROLS FOR HARSH OR DIRTY ENVIRONMENTS
▲A simple device used in applications where the environment is corrosive from production, plant pollutants or other environmental issues. These applications need something to protect the actuator spring chambers from sucking in external air/contaminants during the return stroke, extending valve and actuator life and reliability. The Versa NAMUR ReBreather kit prevents this from happening by redirecting the clean instrumentation air, thus preventing external dirty air from entering the control system.
●How it works
▲The ReBreather block is used on single acting actuators to prevent corrosive atmosphere from entering the actuator spring side. This add on accessory is designed to use available instrument air to fill the spring side, thus assuring only clean air enters the actuator. The instrument air it utilizes on the return stroke is the air from the exhaust cycle of the piston side of the actuator. No additional air is required to complete the cycle and keep the actuator clean.
●Low profile design
▲Available on either Versa’s C or C-316 Series NAMUR valves. The material of the main plate is engineered polymer. All fasteners and speed controls are 316 stainless steel for enhanced corrosion protection and product life.
●Options
▲The starter plate is supplied with a ¼” NPT vent port. The ReBreather may be further customized with the following options
◆Speed control provides closing speed adjustability
◆Vent screen to prevent debris and insects from entering the valve.
◆Dust excluder to prevent debris and insects from entering the valve and with its positive check is also effective in keeping out moisture
