It requires a high number of switching cycles, long service life, and fast valve operation
Performance of programmable valves: 1. Long service life – it is generally required that the seal remains leak-free after 1.5 million cycles of opening and closing； 2. Fast closing speed; depending on the valve diameter, the opening and closing time is between 1 and 2 seconds ； 3. The opening speed is slow; different opening speeds are required depending on the position of the programmable valve ； 4. Programmable valves are required to have bidirectional flow capability ； 5. It is required to have the capability for on-site indication of valve position status and transmission of remote signals. Ordinary valves cannot meet the requirements of pressure swing adsorption units for valves.
Which valves does the original poster refer to as the other valves? This post was last edited by chc1125 on 2008-11-10 16:04.]
What valve can replace a programmable valve? If programming control is required, then it has to be a programmable valve; otherwise, how can you operate it by standing next to it????:funk:
Sichuan Tianli uses angular programmable control valves, while Huaxi uses triple-eccentric butterfly valves; each has its own advantages and disadvantages
I remember there seem to be three methods in Huaxi, right? One is a triple-eccentric butterfly valve, another is a gate valve; I forgot the third one
The reply on the third floor is very comprehensive; it’s from Jiangzi
