instructions
ZSHO pneumatic piston cut-off ball valve (referred to as cut-off ball valve) is an actuator product in pneumatic unit combination instruments, generally used in combination with pneumatic components such as solenoid valves. There are two types of valve body structures: soft sealed valve seats and all metal valve seats, which are used for normal temperature (-40~180 ℃) and high temperature (-60~450 ℃) applications, respectively. Widely used in the cutting or opening of media in gas and liquid transportation pipelines in production sectors such as petroleum, chemical, pharmaceutical, metallurgical, textile, papermaking, sewage treatment, etc., to achieve the production process following a certain procedure.
The cut-off ball valve is mainly composed of a pneumatic piston actuator, a cut-off ball valve, and two parts. According to user needs, a handwheel mechanism can also be configured between the actuator and the shut-off valve, as shown in Figure 1.
When the pneumatic actuator receives a signal from the regulating instrument, it drives the valve stem and ball core to rotate, causing the valve to move from the open (closed) position to the closed (open) position, achieving control over the flow and cutting off of the medium in the pipeline.
Product Features
The valve body is of integral structure and does not have a lower valve cover (only a bottom sealing gasket is provided). The valve core is equipped with upper and lower sleeve guides for stable operation The valve seat is tightly attached to the valve core by a threaded sleeve, and the clamping force and relative position with the valve core can be adjusted to ensure a tight fit between the valve seat and the valve core, reducing leakage The surface of the valve core is ground and partially or completely welded with Stellite alloy to increase surface hardness and improve service life The valve seat is made of two different materials, which can adapt to the needs of different temperature ranges.
