• Description 

Plug valves are forged from high quality alloy steel with heat-treatment, and can provide dependable service for applications such as cementing, fracturing, acidizing, coiled tubing and sand control, plug valves are available in three primary models in 1"×2", 2" and 3" inch bore sizes for standard and reverse flow. These valves are available from 6,000 through 15,000 psi in both Standard and H2S service and can be made in a wide variety of popular end connections including union end, male and female line pipe threaded.

The ends of the plug valve can be connected by union or LP thread connection. All technical parameters and performance meet the specifications of API Spec 6A, with the product specification level being PSL3 and the performance level being PR1. The plug valves produced by our company can be interchanged with similar products in the cementing and fracturing equipment of SPM company.

 

• Operation instructions
  • Select only appropriate plug valve for intended service and check for proper function;
  • Not to mix or assemble components, parts or end connections with different ratings;
  • Not to strike, tighten or loosen pressurized components or connections;
  • Not to exceed the rated working pressure or temperature rating of plug valves;
  • Not to use worn or eroded valves;
  • Not to replace sour gas valves with standard service components;
  • If any leakage is detected, remove plug valves from service.

 

• Maintenance 

• Grease valves after each use:

For standard temperature (32℉ to 250℉) use P/N3256666; For low temperature (0℉ to 50℉) use P/N 3251698

• Grease valve in full open position until grease can be seen through the bore of the valve, cycle valve closed to open position and pump a little more grease into valve while valve is in the full open position;
• Re-grease valves immediately after pumping solvents though them;
• Thoroughly flush valves with clean water after each use to wash any cement or acids that may have been left in the valve if applicable;
• Spray rust preventative oil over exposed threads on valve to prevent rusting during storage;
• Replace damaged grease fittings to prevent leaks and to allow proper greasing of the valve;
• Disassemble plug valves and replace worn parts on a routine basis to prevent corrosion and erosion of the valve body and remove old grease.
