Pneumatic internal thread ball valve is Roland Valve's introduction of foreign advanced technology based on updated design, carefully manufactured products. It is powered by compressed air. The valve stem rotates the valve body by 90° in the valve body, and it can realize valve commutation and one-in two-out or two-into-one function. The product's sealing performance is divided into metal seal and soft seal. It has the advantages of compact structure, small size, good sealing, reliable operation, easy maintenance, easy installation and strong adaptability. Can be widely used in petroleum, chemical, light industry, pharmaceutical, papermaking and other industrial process automation systems for remote centralized control or local control; internal thread connection ball valve and welding ball valve is divided into an overall, two-stage and three-stage, Valve body casting adopts advanced foreign technology, reasonable structure, beautiful appearance, valve seat adopts elastic sealing structure, reliable sealing, easy opening and closing; the stem adopts a sealed bottom-mounted structure, when the valve chamber is abnormally boosted, the valve stem will not be Out.
Pneumatic internal thread ball valve and butt welded ball valve are divided into two-stage and three-stage. The valve body casting adopts advanced technology introduced from Taiwan, with reasonable structure and beautiful appearance. Valve seat adopts elastic sealing structure, reliable sealing and easy opening and closing. The valve stem adopts a bottom-down structure with an inverted seal. When the valve chamber is raised abnormally, the stem will not be washed out. The two-piece and three-piece ball valve connections are additionally welded (BW) socket welding (SW), and all can be equipped with international standard ISO bracket platforms and locking devices. 90° switch positioning mechanism can be set, and it can be locked as required to prevent misoperation. Driving mode: manual, electric, pneumatic
Pneumatic internal thread ball valve
Pneumatic female ball valve and butt welded ball valve are suitable for PN1.0～4.0MPa, working temperature is -29～180°C (sealing ring is reinforced PTFE) or -29～300°C (sealing ring is para-polybenzene) On various pipelines used to cut off or connect the medium in the pipeline.
The use of different materials can be applied to various media such as water, steam, oil, nitric acid, and acetic acid.
