Industrial Valves - Check Valves

Swing Check Valve

Scorpio cast steel valves are designed and manufactured to provide maximum service life and dependability. ALL check valves meet the design requirements of American Petroleum Institute standard API600 & API 6D. BS EN 13709 and generally, Conform to American Society of Mechanical Engineers standard ASME B16.34. VaLves are available in a compLete range of body/bonnet materials and trims.

Modifications Available in Scorpio Valves

  • Trim Changes
  • End Connection Modifications
  • Packing and Gasket Change
  • Operator Mounting
  • Handwheel Extensions
  • Pressure Equalizing
  • Customer Specified Coatings
  • Weld End Bore Changes
  • Oxygen & Chlorine Clearing & Packaging

Eyebolt

For 150Lb-8', 300Lb-8" 600Lb-6" • 900Lb-1500Lb/2500Lb-4"& over. Bolted cover.

BC

Welded cover & Pressure seal bonnet in services requiring frequent cycling or with high pressure/term perature variations.

End Connection

A choice of flanged, WO flanged or butt welding end for piping flexibiLity.

Body to Cover Joint

A male & female joint or tongue and groove joint is used 150Lb to 600Lb valves. Ring joint is used in the body to cover connection in 900Lb & higher rated valves.

Range Of Materials

Standard body/bonnet materials include nine grades of carbon, low alloy & stainless steels. For special applications they can be supplied in other grades of alloy & stainless steeL Threre's a full range of trim materials to match any service optional packing S, gasket materiaLs are available for a fulL range of service conditions.

Outside Lever B Weigh

All external hinge pin swing check valves 12" & smaller are available with an optional outside lever and weight, internal hinge available with all swing check valves.

Seat Rign

Separate heavy duty fulL ported rings for easy maintenance, Screwed or welded connection into body.

Hcu Weighted Mechanical Accumulator

This design can be used to either dampen or assist closing of the check valve disc depending on orientation. by using the hydraulic controL unit to buffer action the disc, the vaLve opens at lower flow rates.
