  • Valve actuators /actuation (TH-VAT)

    Valve actuators /actuation (TH-VAT)

    Valve actuators are devices used to open and close valves. The manually operated valve requires someone to be on site, using a direct or gearbox connected to the valve stem for adjustment. Power-operated actuators, using pneumatic, hydraulic or electric power, can remotely adjust valves, or quickly operate large valves. Power-actuated valve actuators may be the final element of an automatic control circuit that automatically adjusts certain flows, levels, or other processes. The actuator may simply open and close the valve, or it may ...

  • Valve accessories-bonnet bushing bolts nuts (TH-VBN)

    Valve accessories-bonnet bushing bolts nuts (TH-VBN)

    Valve accessories refer to the parts or components to which the valve is assembled; or the parts or components to be re-installed after being damaged. Valve fittings can be divided into two types: standard fittings and optional fittings. Standard fittings refer to the auxiliary parts provided at random. Optional fittings refer to the parts that can enhance product functions and improve product performance in addition to the standard configuration.Accessories can be divided into two categories: standard accessories and optional accessories.Standard ...

  • Valve seat sealing (TH-VSE)

    Valve seat sealing (TH-VSE)

    The valve seat is a detachable surface part in the valve, used to support the fully closed position of the valve plate, and constitutes a sealing pair. The general valve seat diameter is the maximum flow diameter of the valve. For example, the valve seat material of butterfly valve is very wide, all kinds of rubber, plastic, metal materials can be used as the seat material, for example: EPDM, NBR, NR, PTFE, PEEK, PFA, SS315, STELLITE and so on.Introduction of valve seat/sealingElastic sealing material and small actuator...

  • Valve stem shaft (TH-VST)

    Valve stem shaft (TH-VST)

    The valve stem is an important part of the valve, which is used for transmission. It is connected to the actuator or the handle, and the valve core is directly moved or rotated below to achieve the valve switching or adjustment effect.Features of valve stem shaftIn the process of valve opening and closing, the valve stem is not only a moving part, a stressed part, but also a sealing part. At the same time, it is impacted and corroded by the medium, and also produces friction with the filler. Therefore, when selecting the stem material, it must be ...

  •  Valve body (TH-VBD)

    Valve body (TH-VBD)

    Definition of valve body: The definition of “valve” is a device used to control the direction, pressure and flow of fluid in a fluid system. A valve is a device that allows the medium (liquid, gas, powder) in piping and equipment to flow or stop, and can control its flow rate.The valve body is a major component in the valve; there are different mechanical manufacturing methods depending on the pressure level. For example: casting, forging, etc.The valve body of medium and low pressure is usually produced by casting process.The medium and high p...

  • Strainer valve (TH-STV)

    Strainer valve (TH-STV)

    The strainer valve (filter valve) is also called filter: its a device that performs filter pretreatment. The filter valve is the filter equipment necessary for the use of hydraulic control valves and sophisticated mechanical products that are prone to clogging. It is an indispensable device of the pipeline series for transporting media. It is usually installed at the inlet end of equipment such as hydraulic control valves, pressure relief valves, pressure relief valves, and fixed water level valves. It is used to eliminate impurities in the media an...

  • Gate valve  (TH-GTV)

    Gate valve (TH-GTV)

    A gate valve is a gate plate of an opening and closing part. The movement direction of the gate plate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate valve is sealed by the contact of the valve seat and the gate plate. Usually, the sealing surface will be welded with metal materials to increase wear resistance, such as 1Cr13, STL6, stainless steel, etc. The gate has a rigid gate and an elastic gate. According to the different gate plates, t...

  • Ball valve  (TH-BAV)

    Ball valve (TH-BAV)

    Ball valve is a valve whose opening and closing parts (balls) are driven by a valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control. The ball valve is mainly used in the pipeline to cut off, distribute and change the flow direction of the medium. It only needs to be operated with a rotation of 90 degrees and a small torque to close tightly. Ball valves are most suitable for switching and shut-off valvesWith the continuous improvement of production technology and product structure, ball valves...

  • Globe valve  (TH-GBV)

    Globe valve (TH-GBV)

    The globe valve is a tool that relies on the pressure of the valve stem to make the sealing surface of the valve flap closely fit the sealing surface of the valve seat to prevent the flow of media. It is a forced seal valve and is one of the most widely used valves.According to the direction of the channel, the globe valve is divided into four types: straight-through globe valve, direct current globe valve, angle globe valve, plunger globe valve.The structural length of the globe valve is greater than that of the gate valve, and at the same time, the...
