One of the most popular Edward valves is the forged Y-Pattern valve.  This valve is most sold in the 158 figure number—which is available on Petrovalve.com.  Here are 7 reasons why engineers love to specify Edward 158 Y- Pattern valves. 

  1. Improved flow characteristics
      - Y-pattern valves provide a straighter, less turbulent flow path through the valve body.    
      - This reduces fluid friction and pressure drop across the valve.    
      - The design utilizes optimized flow passages to minimize flow direction changes.
  
  2. Structural benefits
     - The Y-pattern allows for a longer, better supported valve stem, with bearings at both the top and bottom.    
     - This improves the stability and durability of the stem.    
     - The rigid body design minimizes body distortions and reduces leakage.
  
  3. High pressure and temperature applications
     - Edward Y-pattern globe valves are designed for maximum flow capacity and minimum leakage in high pressure, high temperature applications.
     - They are commonly used in nuclear power plant cooling systems that operate under extreme conditions.  

  4. Reduced material buildup
     - The straighter flow path minimizes dead spaces where substances like asphaltenes can accumulate.    
     - This helps prevent increased valve torque and line plugging issues.  

  5. Space savings
     - The compact design can reduce the overall footprint compared to using multiple standard valves.    
     - This makes Y-pattern valves well-suited for modular process units with space constraints.
  
  6. Improved sealing
     - The body-bore and hard-faced seat are machined in a single operation to ensure concentric alignment for tight seating and minimized leakage between disc and seat.

  7. Enhanced emissions control:
     - Edward Y-pattern valves can be configured with bellows-sealed or hermetically-sealed stems for minimized fugitive emissions.
