Soft Seated SV Series – NPT

Our Soft Seated Sampling Valve is the original Piston Valve pioneered by Strahman in the early 1920s with a unique design of dual sealing rings. Our Sample Valves provide users with safe, effective, and consistent live product sample extractions from the pipeline under high pressure or vacuum conditions without fear of contamination or internal blockage. 

Our line of Live Extraction Containers and Accessories further enhances its safety features and functionality. Additionally, Spare Parts are often recommended for routine maintenance.

Soft Seated SV Series with NPT connection Features:

  • Rugged investment cast body construction for long-lasting service in challenging environments

  • The standard body is 316SS; other materials are also available, such as Alloy 20, Nickel, Hastelloy B or C, Monel, Titanium, Inconel, and other metals by request

  • ANSI CLASS 600

  • Soft seat design meets ANSI Class VI, bubble-tight shutoff

  • MNPT inlet x FNPT outlet connection, Flanged and Insert connections are available; Socket Weld is available upon request

    • GRAPHITE – Maximum Temp. 1000°F (530° C)
  • Dual sealing ring arrangement keeps the valve from leaking into the atmosphere

  • No internal dead spot cavity – the piston fills the valve interior, resulting in a valid live sample every time

  • Precision-machined piston clears out any material that may solidify within the body during regular operation;

  • Standard piston extensions are 0″, 2″, 4″ and 6″ plus custom sizes upon request in +/= 1/16″ increments
