• Features of explosion-proof electric valve electric device

    Valve using tight seal or valve pressure, valve cover seal washer structure, trustworthy, safe and reliable. The valve adopts an intermediate double plate universal top structure, which automatically adjusts the fit between the valve and the seat sealing surface to ensure that the valve is sealed, while this structure is easy to maintain, saves cost and better valve interchangeability. Seat sealing surface spraying tungsten carbide, by the plasma formation of cobalt chromium alloy, sealing surface hardness is high, wear-resistant, wear-resistant,…

  • The selection of valve electric actuator should be based on what?

    The QOTO valve electric actuator is a device that operates the valve and connects it to the valve. The device is electrically driven and its motion can be controlled by stroke, torque or axial thrust. The performance and use of valve electrical equipment depends on the type of valve, the operating specification of the equipment and the position of the valve in the pipe or equipment. Therefore, it is important to properly select the valve installation equipment and consider how…

  • Problems to be aware of when purchasing imported electric actuators

    1. Drive energy The most commonly used electric actuator drive energy source is a power source or a fluid source. If the power source is selected as the drive energy source, a three-phase power source is generally selected for a large-sized valve, and a single-phase power source can be selected for a small-size valve. General electric actuators are available in a variety of power types. Sometimes DC power can be selected, and the battery can be safely operated by installing…

  • How should electric actuators and pneumatic actuators be chosen?

    Executive agencies can be divided into Electric actuator,,Pneumatic actuators, electro-hydraulic actuators, gas-liquid actuators. This is the most concerned with electric actuators and pneumatic actuators, but there is a big difference between them. There are great differences in performance and price, which affect the choice of users.  1. Main considerations for implementing agency selection   The main considerations for actuator selection are: 1 reliability; 2 economy; 3 smooth operation, sufficient output torque; 4 simple structure, easy maintenance, etc.   2.Electric actuators and comparison of…

  • What should you watch out for when selecting a valve electric device?

    At present, the distribution of the valve market is mainly based on the construction of engineering projects. The largest users of valves are petrochemical industry, power sector, metallurgical department, chemical industry and urban construction department. The petrochemical industry mainly uses API standard gate valves, globe valves and check valves; the power sector mainly uses high-temperature pressure gate valves, globe valves, check valves and safety valves for power stations and some low-pressure butterfly valves and gate valves for water supply and…
