Features and Benefits

• Self-contained valve provides the functions of: Check valve, flow sensing element, bypass flow control valve and multi stage pressure letdown device
• Simplifies the system
• Reduces cost of Engineering,
  Administration, Installation and
  Maintenance of complex, conventional flow control valve and instrument systems
• Eliminates requirement for external source of power and/or instrument signals
• One valve replaces seven interdependent components
• Eliminates multi vendor responsibility and coordination
• Enhances system reliability
• Patented bypass flow control and pressure letdown system
• Assures fail safe operation and pump flow protection
• Eliminates cavitation, flashing, choked flow and/or damage in bypass line
  
  

Complete in-Lineaccessibility

• Allows for adjustment, inspection and/or
  maintenance of all internals without removing the valve from the line or disrupting any piping

Field adjustability

• Enables user to change main flow, bypass flow and switch point
• Accommodates changes in pump operation

True bypass flow modulation

• Assures proper minimum pump flow
• Provides a smooth transition from main flow to bypass flow, thus eliminating piping shock
• Conserves energy

Valves are completely functional tested

• Valve is certified correct for its application
• Assures reliable performance from every
  valve

One valve - four functions

• Check valve - prevents reverse flow
• Instrumentation - flow sensing and bypass activation
• Bypass flow control - assures minimum pump flow
• Pressure letdown - reduces pressure of fluid returning to its sources
