Notes / Remarks:

  1. Jmenovitý tlak: Class 125 per ASME B16.1 standard. Maximum allowable working pressure is 175 psi for WOG (Water, Oil, Gas) a 200 psi for saturated steam at ambient temperature.
  2. Design sedadla: Bronze seat faces are achieved by overlaying (welding) or inserting bronze rings on both body and wedge, ensuring corrosion resistance and long service life.
  3. Konstrukce představce: Outside Screw and Yoke (OS&Y) design isolates the stem threads from the media, allowing in-line maintenance and providing visual indication of valve position.
  4. Gearbox Recommendation: Due to the large size (14″), a gearbox operator is strongly recommended for ease of operation and to reduce manual effort.
  5. Applicable Standards: This datasheet is based on MSS SP-70 and ASME standards. Please confirm specific standard revisions and project special requirements before procurement.
