Linear Piston Vibrators are commonly used as discharge flow aids on bins, hoppers and chutes in the chemical, foundry and concrete industries. They require a quick-acting valve to start and stop. The valve can be a manual type (activated by hand or foot), or it can be an electrically controlled solenoid type (activated by a switch or push button). Oak piston vibrators come with threaded inlet and outlet ports and exhaust mufflers. They are made of ductile iron, machined to precise tolerances. Pistons are hardened using a Nitro Fusion process for longer wear resistance, better corrosion resistance, no distortion, improved fatigue strength and excellent sliding properties. Air-cushioned piston vibrators are recommended for use in hazardous areas and are ideal for atmospheres containing explosive dust, vapour or gas. A proper explosion-proof valve to ensure safe operation in hazardous areas must activate the vibrators.
