Wheatley series 500 check valves

The Wheatley™ series 500 check valve is a fire-tested flanged-end swing check valve with full-open, through-conduit design for low pressure drop and less turbulence. It has been a staple of the oil and gas industry for years.

• Downstream of pumps and compressors to prevent reverse flow
• Gas compressor stations
• Gas storage
• Gas processing stations
• Land exploration and development drilling
• Pump stations and wellhead inspection facilities
• Hydrogen service

Wheatley series 500 check valves protect your pumps by preventing backflow. The top-entry design enables inline repairs, saving time, while the fullbore through conduit reduces pressure drop and turbulence, facilitating passage of pigs and spheres. Wear and tear is transferred to an inexpensive replaceable part, extending valve life.
