High platform Ball

ZSHO pneumatic piston valve off (the cut off valve), is a pneumatic unit in the instrument cluster actuator products, generally a combination of solenoid valves and pneumatic components use. Soft seal valve seat structure has installed all-metal seat and two, respectively, for normal temperature (-40 ~ 180 ℃) and high temperature (-60 ~ 450 ℃) applications. Widely used in gas oil, chemical, pharmaceutical, metallurgy, textile, paper, sewage treatment and other production departments, the liquid medium in the pipeline cut or open, according to the production process in order to achieve certain procedures. , Cut-off valve, mainly composed of two parts by a pneumatic piston actuator off valve. According to user needs can also be configured hand wheel between the actuator and shut-off valve, the structure shown in Figure One. As for the medium flowing in the pipeline, cutting off control of pneumatic actuators adjust the instrument receives a signal from a drive stem, ball core rotates the valve from the open (off) position to the OFF (open) position, reach . Features Body for the overall structure, and no bottom valve cap (provided only the bottom gasket), the valve has upper and lower sets of guide, stable;? Valve seat by a threaded sleeve tight fit on the spool, pressed force and the relative position of the valve is adjustable to ensure the seat, plug tight fit, reduced leakage;? spool surface by grinding, welding part or all of Stellite, increasing surface hardness, improve life ;? valve consists of two different materials, able to adapt to the needs of different temperature ranges.
