• What is the classification of valve electric actuators?

    Classified by operating system 1, the wind system uses electric valves Electric conditioning damper ※ Smoke exhaust valve ※VAV damper 2, the water system uses electric valves Electric two-way valve ※Electric three-way valve ※balance valve Electric air valve classification Electric actuators are also classified according to the type of actuator. 1. Use the valve of the quarter-turn actuator Fan coil electric valve Manipulating the ball valve Butterfly valve 2. Valves using straight stroke actuators Compact control valve Seat valve Water…

  • What are the benefits of new butterfly valves for regulating flow in pipes?

    The new butterfly valve can better regulate the pressure and flow in the pipe. For process industry enterprises, water treatment and public institutions, the regulation of water flow in pipelines is a very demanding mission. The Electric actuator B + RS160 knows that the cavitation effect and water hammer effect of water flow will bring great constraints to the planning of process equipment, reduce the production power of process equipment, and increase the cost of process equipment protection and maintenance….

  • 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…

  • Common fault analysis and processing of valve electric actuator

    Valve electric actuators have been widely used in the industry, but because of the large number of manufacturers producing electric actuators, the working principle is different, and the reliability of work varies greatly. Therefore, the electric actuator is a kind of equipment with high failure rate. Based on my own experience in the work, I analyze the common faults of the electric actuator and propose corresponding solutions. The electric actuator mainly consists of a power board, a main board, a…

  • Need to pay attention to the output speed when purchasing the actuator?

    If the opening and closing speed of the valve is too fast, it is easy to cause water hammer. Therefore, the appropriate opening and closing speed should be selected according to different operating conditions. Electric actuators know that valve electric equipment has its special requirements, that is, it is necessary to restrain torque or axial force. Generally, the valve electric equipment uses a coupling that constrains torque. When the electric equipment standard is determined, its control torque is also determined….

  • 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…

  • Safety Relief Valve FAQs

    Companies that repair, test, maintain or supply valves routinely receive inquiries from end users about safety-relief valves. Here are a few questions frequently asked of one VMA member. Q: What is the proper way to install a safety or safety relief valve (SRV)? A: Mount SRVs in a vertical, upright position. Installing an SRV in any position other than vertical (within plus or minus one degree) will induce misalignment of moving parts, which will adversely affect its operation and may…

  • Valve electric actuator manual and troubleshooting

    Valve electric actuator instructions Valve electric actuator instructions: valve electric actuators must be used in accordance with the formal use, if you do not understand the random operation, it will cause damage to the valve. It is recommended that everyone use it after professional training, which is more beneficial to us. So how should this machine be maintained? 1. We see that it is maintained in a long-term manner, not in the short term. After using the machine, you should…

  • The role and classification of valves

    Valves have many functions. Different valves should use different valves. Different types of valves have different configurations, and these functions are effective means to control the process and ensure safety. Valves are generally divided into automatic valves and drive valves. Automatic valves (such as safety valves, pressure reducing valves, steam traps, check valves) rely on changes in the pressure of the device or pipeline medium to achieve the purpose of opening and closing. The driving valve (gate valve, globe valve,…

  • Teach you to choose an electric actuator for the valve

    The valve electric device is an indispensable driving device for realizing valve program control, automatic control and remote control. The movement process can be controlled by the stroke, torque or axial thrust. So how can we choose a suitable valve electric device? From the point of view of sales, what parameters do we need to determine which valve electric device the customer needs? The following is a small series to explain in detail: Of course, the easiest thing is that…
