A Valve

This is the standard, round, full-size, one-piece valve that has been used successfully in columns around the world for over 50 years.  

• It is provided in several leg lengths to accommodate various tray deck thicknesses 
• It is normally dimpled to help prevent sticking to the deck, but can be flush-seated if needed 
• The orifice can be made to prevent the valve from spinning 
• Dual valve weights may be used in alternating rows to extend the already wide operating range
