Pneumatic three-piece screw ball valve
详情介绍
product description
One, pneumatic three - piece internal screw ball valve product characteristics
Pneumatic three - piece internal screw ball valve is divided into integral, two - stage and three - stage. The body casting adopts the advanced technology imported from abroad, which is reasonable in structure and beautiful in shape. Seat adopts elastic sealing structure, reliable sealing, easy opening and closing. The valve stem adopts reverse sealing lower mounting structure, when the valve cavity is abnormal boost pressure, the valve stem will not be rushed out.
