When a valve is manufactured in a certain specification, an authoritative institution should be entrusted to perform the following performance tests: ① The opening and closing torque of the valve under working pressure;

Pneumatic butterfly valve is slow? It directly affects the production and the operation of a subsequent machine. What is the reason for the slow action of the expected butterfly valve?

A linear actuator is any device that generates work by converting nonlinear energy in linear motion. There are many primary energy sources used in linear actuators, from electric motors to fluid and air pressure and thermal expansion.

Linear actuators have a quantity of amazing processes, machines, and devices that provide linear drives. These devices from inconspicuous DVD tray openers to produce tens of thousands of pound of pressure giant hydraulic plunger.

Such an actuator converts the rotational energy of the motor into a straight movement using a cam or a lead bar device. The screw example is a very popular choice because it provides a wide range of extended length potentials.

Hydraulic aerodynamic actuators utilize pressurized gas or liquids to achieve linear motion and have the largest output potential. These systems include a piston, which is in a sealed tube, and both ends have valves. The piston is connected to an actuator rod, and the rod passes through the seal at ......
