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.
