Bottom Outlet Plug Valves

Midland bottom outlet plug valves are the industry standard for general service bottom outlet applications.

Features & Benefits

Spring-loaded plug ensures the valve remains closed in event of an incident
Exclusive, low-profile design eliminates the need for AAR required skids - approved for protection level A of AAR circular D.V. 2007
O-ring seals provide resilient sealing and improve valve performance compared to Teflon seated ball valves
Triple-seal design on the plug provides exceptional redundant sealing for long valve service life
A wide variety of O-ring materials are available, including PFA encapsulated O-rings which offer universal compatibility with most commodities, including ethanol and petroleum products
Clean, cavity-free design prevents entrapment or isolation of media inside the valve body
