  • Ball Valve
  • Gate Valve
  • Globe Valve
  • Check Valve
  • Butterfly Valve
  • Strainer
  • Ball Valve
    Ball valve is used to on/off the medium in pipeline and is widely used in petroleum refining, chemical, electric power, long-distance transportation pipeline, paper making, pharmaceutical, water conservancy, municipal, steel, etc. Special consideration is taken to strength, safety and resistance to harsh environment during designation. It's suitable for various corrosive and non-corrosive mediums. Different materials may be selected for transportation of water, steam, oil, natural gas, nitric acid, acetic acid, oxidant and urea. Ball valve has compact structure and reliable sealing. Its sealing surface and spherical surface are closed normally, which make it resistant to flush erosion from the medium and easy to operate and repair.
  • Gate Valve
    Gate valve also known as a sluice valve, is a valve that opens by lifting a barrier out of the path of the fluid,opening and closing part of gate valve is flash board. Its direction of motion is perpendicular to the direction of fluid. The valve is usually used to cut off medium. The entire flow channel is a straight-through passage when the valve is fully open, and the pressure loss of medium running is minimum, It's not suitable for adjustment or throttling. Various materials may be selected for transportation of water, steam, oil, natural gas, nitric acid, acetic acid, oxidant and urea.
  • Globe Valve
    Globe valve is a kind of valve with close part making a linear motion along the center line of valve seat. As the opening and closing stroke of valve stem is relatively short, with reliable cut-off function, the change of valve seat orifice and stroke of valve clack are proportional, the valve is really suitable for flow regulating. It may be used for cuting off or regulating as well as throttling of fluid pipeline for city water, sewage, construction, food, electric power, medicine, metallurgy and textile.
  • Check Valve
    Check valve, non-return valve or one-way valve is a kind of mechanical device and a valve, which normally allows fluid (liquid or gas) to flow through it in only one direction. An important concept in check valves is the cracking pressure which is the minimum upstream pressure at which the valve will operate. Typically the check valve is designed for and can therefore be specified for a specific cracking pressure.
  • Butterfly Valve
    Butterfly valve is a kind of valve that takes a disc as closing part (butterfly board) which rotates around the valve axis to achieve opening and closing, mainly used for cut-off and throttling on pipeline. A plate or disc is positioned in the center of the pipe,the disc has a rod passing through it that is connected to an actuator outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow,the flow of medium may be controlled by changing deflection angle of butterfly board. Butterfly valve is suitable for pipeline that transports various corrosive, non-corrosive fluids in producer, coal gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical smelting and power environmental protection, building water supply and drainage and other engineering systems for regulating and cutting off medium flow.
  • Strainer
    Strainer is an indispensable device on the pipeline of the conveying medium. It is usually installed at the inlet of a pressure reducing valve, a pressure relief valve, a fixed water level valve or other equipment to eliminate impurities in the medium to protect the normal operation of the valve and equipment. use. When the fluid enters the filter cartridge with a certain specification filter screen, its impurities are blocked, and the clean filtrate is discharged from the filter outlet. When cleaning is required, just take out the detachable filter cartridge and reload it after treatment, the use and maintenance of the filter is extremely convenient.
