2-Way Sensing Valve Model 4109 - Vibro-Guard Overview AMOT Model 4109 Vibro-Guard Valve is a 2-way acceleration sensing valve with optional electric microswitch. Failing bearings, broken blades, cracked, broken or bent shafts, misfiring, and accumulated deposits are a few of the items which the Vibro-Guard can detect. This unit is weatherproof and corrosion protected for salt spray atmospheres (Gulfproofed). Typical applications l Motors l Engines Model 4109 2-Way Sensing Valve l Pumps l Compressors l Fan drives l Any moving equipment Key benefits l Gulf-proofed finish l Pneumatic and electric versions available l Reliable repeatability l Pneumatic reset/override available

2-Way Sensing Valve - Model 4109 Vibro-Guard Operation Model 4109 makes use of a pivoted lever assembly with a high strength, potted magnet near the end opposite the pivot. When the unit is reset, the magnet is thrust toward the steel armature imbedded in the base and is held there by magnetic force plus the force of the loading spring until the inertia of the lever assembly exceeds the holding force of the magnet and spring. When this occurs, the lever assembly snaps to the tripped position and remains there until manually or pneumatically reset. Tripping of the lever assembly allows the...

2-Way Sensing Valve - Model 4109 Vibro-Guard Adjustment Vibro-Guard is factory set at approximately 2 G’s in the horizontal position. Should this setting not be suitable for the intended application, an adjustment will be necessary. To adjust the trip point, isolate the Vibro-Guard from the safety circuit and bring the protected machine to its rated speed and load. Remove Cover (47) and check Lever Assembly (24) to see if the unit has tripped. If it has, attempt to reset by firmly pressing the rectangular leaf spring on the lever assembly at Point B (see assembly drawing on the back page)....

2-Way Sensing Valve - Model 4109 Vibro-Guard Typical piping diagram This circuit will actuate a Master Safety Control or Pressure Operated Valve upon excessive vibration as detected by the AMOT Model 4109. The Pneumatic Indicating Relay will show the cause of the shutdown and the Model 4057 Valve can be used to remotely rest or override the 4109. PSESSUBE OPERATsD niJLllUHE IHLET AECLSSTDEHTEh I'JPJhG Properly applied and installed, Model 4109 requires practically no maintenance. An inspection of the unit at yearly intervals is adequate to detect and make provision for normal wear. It is...
