Notes / Remarks:

Penilaian Tekanan: Class 125 per ASME B16.1 standard. Maximum allowable working pressure is 175 psi for WOG (Water, Oil, Gas) and 200 psi for saturated steam at ambient temperature.
Reka bentuk tempat duduk: Bronze seat faces are achieved by overlaying (welding) or inserting bronze rings on both body and wedge, ensuring corrosion resistance and long service life.
Reka bentuk batang: 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.
Gearbox Recommendation: Due to the large size (14″), a gearbox operator is strongly recommended for ease of operation and to reduce manual effort.
Applicable Standards: This datasheet is based on MSS SP-70 and ASME standards. Please confirm specific standard revisions and project special requirements before procurement.
