Electric actuators are mainly matched with valves and used in automated control systems. There are many types of electric actuators with different operating modes. For example, a 1/4-turn electric actuator outputs angular torque, and a linear stroke electric actuator outputs displacement thrust. The type of electric actuator used in the system should be selected according to the working needs of t…

Electric actuators and pneumatic actuators are both commonly used equipment in our current actuators. The main difference can be seen from the name, which is the difference in driving methods. One is electric drive and the other is pneumatic drive.…

The switching action of the actuator of the pneumatic actuator is driven and executed by the air source, which is called DOUBLE ACTING, which is double acting. SPRINGRETURN, that is, single-acting, only open or close is driven by air source, and the opposite action is reset by spring.…

AT pneumatic actuator is a double-piston rack and pinion rotating structure design. It is divided into double-acting and single-acting. It is suitable for various indoor or outdoor non-corrosive working environments.…

The applications of fully welded ball valves are as follows: All kinds of industrial equipment: all kinds of heat treatment pipelines, all kinds of industrial gas and heating pipelines.…

The technical characteristics of the welded ball valve are as follows: 1. The valve body structure is integrally welded, and there will be no external leakage. 2. The valve seat is composed of PTFE sealing ring and spring, and has strong adaptability to pressure and temperature changes, and will not cause any leakage within the scope of use.…

The safety valve is one of the three indispensable safety accessories on the boiler. It plays an important role in the control of the internal pressure limit of the boiler and the safety protection of the boiler. When the pressure in the boiler rises above the specified value, the safety valve is automatically opened to relieve the pressure and discharge steam…

The safety valve often has the problem of internal leakage during take-off, how to solve it?…
