V16 series Severe Service Union Bonnet Valves
  • Up to 6000psig (413 bar) Up to 648? (1200?)
  • SS316 and Alloys
  • Stem seal below actuating threads
  • Non-rotating globe pattern stem tip
  • Electra OD 1/4 - OD 1 inch
  • Pipe thread 1/8 -1 inch
  • Pipe socket weld 1/4 - 1/2 inch
  • Handle-Closurestandard S316 bar handle, optional knob, and Aluminum Bar Handle
  • External Packing Bolt-allows packing adjustment without the valve disassembly.
  • Roll threaded and hard chrome plated stem-is for long valve life.
  • Panel Mounting Nut- is standard and permits valve to panel or actuator.
  • Union Nut-prevents accidental disassembly of the valve in service..
  • Stem Packing below the threads-prevents media contamination and thread lubricant washout.
  • Back Seating Stem-is blow-out proof design in severe service.
  • Non-Rotating Stem Tip at Closure-s for maximum metal seat life and positive seal.
 
Features  
  • Pressure up to 6000 psig (413 bar) @ 37C (100F).
  • High Temperatures up to 300C (572F) with standard PTFE packing; up to 649C (1200F) with Grafoil packing.
  • Standard S316 stainless steel, optional Alloy 20, and Alloy C276 construction.
  • Valve stem back seating against the beveled edge of bonnet ensures safety in severe service, this also prevents max. leakage thru. bonnet when a packing fails.
  • Standard non-rotating stem tip and stem packing below the threads design

Packing Adjustment and Actuation Torque
  • Extreme temperature fluctuations while valve in service may require packing adjustment.
  • Valves that have not been actuated for a period of time may have a higher initial actuation torque.
 
Factory Test
  • Every valve is tested with the nitrogen @ 1000 psig (68 bar) for leakage at the seat to a maximum allowable leak rate of 0.1 scc/min. The packing is tested for no detectable leakage. Optional hydrostatic shell test with additional cost is performed with pure water at 1.5 times the working pressure.

Valve Ratings with optional Stem Packing
Valves with optional packing may affect the valve rating depending on the valve material. Please see the table below for the rating of valves with optional packing materials. To order valves with factory-assembled optional packing, use the packing material designator from the table below as a suffix.
PEEK PVX (polyetheretherketon) packing is coming with PEEK packing supports. PEEK packing is not for use with normally open or normally closed pneumatic actuating valves.
Grafoil (Flexible Graphite) is a high temperature packing material that requires a load on the material to generate a seal. Grafoil packing is not for use with pneumatic actuating valves.

Sour Gas Valves

Cracking of low or high strength materials in the presence of hydrogen sulfide and water in combination with a tensile stress is called sulfide stress cracking (SCC). For use valves in sour gas, materials for wetted components are selected to NACE MR0175.  To order, use designator - SG as a suffix to the basic ordering number.  Sour Gas valves are available for valves with male & female pipe end connections.  Please refer to ordering information below.

 

Actuators

Pneumatic Air Acutator and Mounting Bracket are available. For details, please contact the authorized Electra distributor in your region.

 
Optional Handles

S316 bar handles are standard. Optional anodized black aluminum bar handles and black colored plastic knob are available. To order valves with factory-assembled optional handle, use the packing material designator below as a suffix.  Please refer to ordering information below AH: Black Aluminum Bar Handle, BK: Black Color Plastic Handle.
