50B-5KG<br/>Pressure Relief Valve

50B-5KG Pressure Relief Valve

[50B-5KG]
The Model 50B-5KG Pump Suction Control Valve is designed specifically for Fire Pump Suction Control Service in commercial fire protection systems.  It modulates to maintain the pump discharge in relation to the suction head available, thus assuring that the suction head pressure does not fall below the pre-set minimum.  When there is a demand in the Fire System, the pump is started, delivering water from the supply source to the area of demand.  
 
By maintaining minimum pressure requirements in the supply main, the main is protected from possible damage or backflow conditions.  Also, a minimum supply pressure is provided for local fire apparatus.
 
Advantages include:
  • Adjustable Opening Speed For Pump Suction Protection
  • Pilot Control Provides Wide Flow Range With Minimal Pressure Variations
  • Controlled Closing For System Protection
  • Modulates Within 5% of Setting for Accurate Pressure Control
  • Pressure Setting Adjustable
  • Pressure Setting Not Affected by Pressure at Valve Discharge
