    • Insulating Jacket Ball Valve

      Insulating jacket ball valve has good heat and cold insulation properties, and the valve size is consistent with pipe diameter, and it can effectively reduce heat loss of medium in pipelines.

    • Low-temperature Globe Valve

      Low-temperature globe valve means a valve whose closing member (valve clack) moves along the centerline of valve seat. Based on this moving form of valve clack, the opening of valve seat varies in direct proportion to the stroke of valve clack. Because the valve stem opening or closing stroke of this kind of valve is relatively short, it has reliable cut-off function, and because the opening of valve seat varies in direct proportion to the stroke of valve clack, this kind of valve is very suitable for flow regulation. Therefore, this kind of valve is very suitable for cutting off or regulation and throttling.

    • Low-temperature Gate Valve

      The opening/closing member of low-temperature gate valve is gate, and the gate´s direction of motion is perpendicular to the direction of fluid; gate valve can only be fully opened or fully closed but not used for regulation and throttling.

    • Y-type Filter

      This series of valves are a kind of devices necessary for medium conveying pipe systems, which are used to filter mechanical impurities in medium to protect the parts of equipment and pipelines from wear and blocking. All inner parts are made of stainless steel, and sturdy and durable. With small volume, fine filtration pore, small resistance, high efficiency, easy installation and maintenance, and low cost, the filter can meet the needs of various pipelines. The valve is widely applied.

    • Three-way Ball Valve

      Three-way ball valve is divided into Type T and Type L. Type T can interconnect three orthometric pipes and cut off the third passage to play a role of separation and combination. Type L can only connect two orthometric pipes but not maintain interconnection with the third pipe at the same time, and only plays a role of distribution. Q48,Q49.

    • High-temperature High-pressure Metal Hard Seal Ball Valve

      Hard seal ball valve is used to cut off medium in pipelines under such operating conditions as high temperature, high pressure, high sealing performance, high viscosity, and particulate medium, with long service life and high reliability.

    • Solenoid Relief Valve (PCV)

      Solenoid relief valve (PCV) is applicable to supercritical and ultra-supercritical thermal power unit, and solenoid relief valve is installed at superheater together with safety valve for overpressure protection. Solenoid relief valve opens before action of safety valve to discharge excess steam to avoid frequent popping of safety valve and prolong its service life. It can be manually controlled or automatically controlled.

    • Energy Relief Valve (ERV)

      Energy relief valve (ERV) is applicable to supercritical and ultra-supercritical thermal power unit, and energy relief valve can replace solenoid relief valve (PCV) to be installed at superheater together with safety valve for overpressure protection. Energy relief valve opens before action of safety valve to discharge excess steam to avoid frequent popping of safety valve and prolong its service life.

    • Reheater Safety Valve

      SFIA series safety valve is applicable to supercritical and ultra-supercritical thermal power unit, which is installed at inlet/outlet pipeline of reheater for overpressure protection to ensure the safe operation of power unit. The product passes the certification by the National Energy Administration, realizing the localization of the first domestic reheater safety valve and filling a domestic gap.

    • Superheater Safety Valve

      SFIA series safety valve is applicable to supercritical and ultra-supercritical thermal power unit, which is installed at superheater header for overpressure protection to ensure the safe operation of power unit. The product passes the certification by the National Energy Administration, realizing the localization of the first domestic superheater safety valve and filling a domestic gap.
