Product Introduction:
3-piece ball valve consists of three body segments connected by through bolts, including end body, central body and another end body.
It can be disassembled for seat replacement without removing the entire valve from pipeline, greatly reducing maintenance downtime.
Available in threaded, flanged, butt weld connection, manual/pneumatic/electric actuator optional.
Material: SS304, SS316L, Carbon Steel WCBSeat: PTFE/RPTFE soft seat, metal hard seat for high temperature
Pressure: PN16~PN64, Class150~300,
Size: DN8-DN200
Features:
Easy inline maintenance, replace seal directly without pipeline disassembly;
Full bore design for minimum flow resistance;
Bidirectional sealing, compact structure, high pressure resistance;
Sanitary polished version available for food & pharmaceutical service.
Application: Chemical pipeline, food & beverage, natural gas, hydraulic system, water treatment, marine piping.
Key technical parameters:
1. Nominal diameter: DN8 - DN200
2. Nominal pressure: PN16, PN25, PN40, PN64; American standard Class150/300
3. Flange / Thread standards: National standard GB, NPT American thread, BSPP British pipe thread
4. Applicable media: Water, steam, natural gas, diesel, hydraulic oil, acid-base solution, compressed air
5. Leakage grade: Soft seal VI grade (bubble-free zero leakage), hard seal IV grade.
Advantages:
1.Online maintenance, with extremely low maintenance cost.
Loosen the tension bolts of the valve body, directly disassemble the three-section valve body, replace the valve seat seal without disassembling the entire valve, reducing pipeline downtime, suitable for corrosive pipelines that require frequent maintenance.
2.High structural strength, good pressure resistance performance
The entire valve body is securely fastened by long bolts, the rigidity of the shell is better than that of the two-piece ball valve, and it can achieve the high-pressure specification of PN64.
3.Full diameter flow, minimal resistance
The ball body's through hole is basically the same as the inner diameter of the pipeline, the pressure loss when fully open is close to that of a straight pipe, and the energy consumption for transportation is lower.
4.Bidirectional sealing, installation without flow direction restrictions
The inlet and outlet can be interchanged, the pipeline renovation and adaptation to reverse medium are highly compatible.
5.Rich functional configuration
Can be equipped with anti-static, fireproof structures, longer valve stem, and drain ports， suitable for gas， high-temperature and high-risk scenarios.
6.Easy to clean and maintain
The sanitary three-piece ball valve can be mirror-polished， facilitating cleaning and sterilization， suitable for food and pharmaceutical clean pipelines.
All valves are equipped with professional export protective packaging.
With protective caps on the sealing surfaces, rust-proof treatment, and shock-absorbing material filling to ensure intact transport; the loading is secure and safe.
We can also customize packaging according to customer requirements.
Regarding transportation methods, we can provide appropriate transportation options based on the cargo requirements and the customer's timeliness requirements.
Common transportation methods include: sea freight, air freight, land freight, and express delivery.
