feature
1. High sealing reliability: Adopting a metal hard sealing structure, the sealing surface between the valve disc and the valve seat is usually welded with hard alloy and precision ground. Under the high-pressure thrust of the pneumatic actuator, it can achieve a tight metal wire seal with a high sealing level, suitable for harsh working conditions such as high temperature, high pressure, and zero leakage requirements.
2. Smooth opening and closing, precise adjustment: When the valve is opened and closed, the valve disc moves vertically in a straight line without any obstruction. With the precise control of pneumatic actuators (which can be equipped with attachments such as locators), accurate flow regulation and stable and reliable switch positioning can be achieved, especially suitable for automation systems that require process control.
3. High temperature, high pressure and erosion resistance: The sturdy rigid structure, high temperature resistant metal valve body and hard alloy sealing surface enable the valve to withstand high system pressure and temperature , and have good anti erosion and wear resistance to steam, high-speed fluids and media with small particles.
4. High fluid resistance: Due to the non straight passage in the valve chamber, the medium needs to change direction (in an "S" shape), resulting in a high flow resistance coefficient. In the fully open state, the pressure loss is higher than that of gate valves or ball valves of the same specifications.
5. Longer structural length: Compared with butterfly valves, ball valves, etc., globe valves have a higher structural height, longer structural length, larger volume and weight, and have certain requirements for installation space.
6. Automatic and efficient driving mode: It is driven by pneumatic actuators and uses compressed air as the power source. It has a fast response speed and can achieve remote centralized control, rapid opening and closing, or emergency shutdown. It is one of the key equipment for industrial automation pipeline control.
