Product introduction:
With excellent performance and reliability, fully welded ball valves are widely used in underground pipeline scenarios such
as urban gas transmission and distribution networks, central heating systems, natural gas long-distance pipelines, and
pressure regulating stations. After 30 years of technological accumulation, through continuous R&D innovation and iterative
upgrades in product quality, this series of valves has gained deep trust and high praise from customers in more than 30
countries and regions worldwide. In terms of structural design, fully welded ball valves adopt an integral full-welding process
for the valve body, fundamentally eliminating potential leakage hazards from traditional flanged connections and achieving
leapfrog improvements in both internal and external sealing performance. The valve body is made of high-quality pipe
materials or A105 forgings. Through precision forging and non-destructive testing processes, it ensures that the valve body
has no casting defects such as sand holes or air pockets, thus eliminating the risk of valve body leakage from the source.
This design not only significantly reduces sealing maintenance costs in engineering construction but also shortens on-site
installation and debugging time by minimizing leakage hazards, providing efficient and reliable solutions for urban energy
infrastructure construction.

Product features:
1. The body uses the all welded structure, there won't be the phenomenon such as external leakage, the valve structure is more compact, easy instalation.
2. Low operating torque: valve adopts the self-lubricating backing PTFE metal collar, small friction torque, to ensure that the valve to operate under the condition of the low torque.
3. Double block and excretion function (DBB): both sides ofthe valve in the cloed position and the ballunder pressure at the same time, the bodylumenofmedium (gas or liquid) from the drain valve discharge.
4. Double piston efect seat structure design: both sides ofthe seat underthe action of pressure seal(double piston effect,. Double sealing seat desigrfeatures: once the upstream seat is damaged and leaking, medium pressure on the downstream side intothe valve cavity, the seat into the sphere closcontact,can sealthe downstream seat.
