The ZSHO series valve is a straight-through valve. The ball can be fully opened to fully closed or fully closed to full opening by only turning 1/4 turn around the shaft. The product can provide a variety of materials, and the internal design is diversified. It is widely used in most applications in the industrial and commercial fields for proper control needs.
O-type cut-off ball valve is currently the leading technology in domestic technology. It adopts the original imported pneumatic actuator. The surface of the core is hardened by special process to make the surface smooth and wear-resistant. The valve seat and sealing material are made of carbon fiber material with high temperature resistance and wear resistance. The product structure is exquisite and reasonable. The perfect crystallization of advanced technology.
The O-type ball valve is a rotary type cut-off ball valve, which is an execution unit in a pneumatic unit combination meter, and is generally used in combination with a pneumatic component such as a solenoid valve. The valve body structure has two kinds of soft seal seat and all metal, which are used for normal temperature (-40~180°C) and high temperature (-60~450°C). The product has high transmission efficiency, large thrust, good sealing performance, large rated flow coefficient and strong interchangeability of parts. Therefore, it is widely used in the cutting or opening of medium in gas and liquid conveying pipelines of petroleum, chemical, pharmaceutical, metallurgy, textile, papermaking, sewage treatment and other production departments, so as to achieve the production process according to a certain procedure.
The soft seal structure adopts the lip type seal seat, which makes the valve seal seat automatically compensate for the change of medium pressure and temperature during operation, so that the valve is always tightly sealed, and the operation is reliable and safe.
The fixed O-type ball valve spool and the valve stem rotate, and when the switch rotates the spool, the valve seat is always in close contact and has a strong shearing capability. The valve seat is preloaded by the aid spring or butterfly spring, with automatic compensation, self-sealing and automatic pressure relief in the valve cavity. Use with high temperature, high pressure and large diameter occasions.
It has a two-way sealing function.
Easy-to-remove and assembled trims for easy maintenance and service.
The application of advanced materials and advanced processing methods (surface polishing, surfacing, titanium oxide, heat treatment or surface plating of chromium nitride and sprayed tungsten carbide) make the valve long life and high reliability.
Side-mounted handwheels can be installed.
Highly reliable actuator and stem connection.
