Exhibitor Information
ZHEJIANG JODITH INDUSTRY CO.,LTD.
Zhejiang Jodith Industry Co., Ltd. is a professional valve manufacturer integrating R&D, production, inspection, and global sales. With years of expertise in the industrial valve sector, our core product portfolio comprises ball valves, gate valves, globe valves, check valves, and stainless steel flanges. All products are manufactured in strict compliance with major international standards including ASME, API, DIN, and GOST, and are extensively utilized in industries such as petrochemicals, power generation, metallurgy, water treatment, and long-distance pipeline systems. Backed by reliable quality, our products have been supplied to numerous large-scale engineering projects and end users worldwide.
Structural Features
1,Full-Bore Design – Flow diameter matches pipe ID. Low flow resistance and pressure drop reduce pumping energy. Ideal for long-distance pipelines and applications with strict pressure drop requirements.
2,Flexible Wedge Disc – Precision integral casting with excellent rigidity. Optimized wedge loading ensures tight seating contact. Elastic deformation compensates for thermal expansion/contraction, maintaining reliable sealing under temperature fluctuations.
3,OS&Y Construction – Stem nut mounted on yoke. Stem rotates and moves axially. Valve position visibly indicated by stem extension height – no instruments needed, facilitates field inspection, reduces operating errors.
4,Blowout-Proof Stem – Retention device at stem bottom prevents ejection in case of packing failure or pressure surge – ensures operator and equipment safety.
5,Optional Seat Construction – Seal-welded: seat ring fusion-welded to body, no back-leakage path, for critical high-temperature/pressure services. Threaded: seat screwed into body for easy on-site replacement, reducing maintenance costs. Both options available.
Operational Features
Bidirectional Sealing – Symmetrical sealing faces on both sides of the disc provide positive shutoff in either flow direction. No flow-direction consideration during installation – simplifies field assembly and prevents sealing failure due to incorrect orientation.
Packing Replacement Under Pressure – With valve fully open, back-seating isolates packing area from line pressure. Packing can be replaced online without system shutdown or media drainage – avoids production losses.
Flexible Material Options – Body standard in WCB, sealing faces hardened with 13Cr stainless steel – corrosion and galling resistance for water, steam, and oil services. Alternative materials: CF8/CF8M stainless steel, Inconel, Monel – for sour service, high-temperature/high-pressure, and demanding applications.
