Isolation valve
Thread Content
Our company needs to purchase four cut-off valves with a DN250 size and PN4.0 pressure rating for technical upgrades. What domestic valve options are available?
It depends on your medium. Also, it depends on the function of this valve and your requirements for it
There must also be conditions regarding temperature and medium. It doesn’t matter which company is chosen; as long as they meet the requirements and have the necessary qualifications, that’s fine. Manufacturers capable of producing such pressure valves are all acceptable. For reference.
Wuxi Baoniu, Wuzhong Valves, Suzhou Neway – just go and ask them. They will select a model for you based on the technical information you provide
Has anyone used the cut-off valves made by Antwei, Jiangsu Hongguang, or Zhejiang Lino? How is it working?
Let me know what model you need; I can provide corrosion-resistant options
If a high level of leakage resistance is required for the shut-off valve, a ball valve should be chosen. Antewei’s products are acceptable; I haven’t used the other two brands. Sichuan Suk and Shanghai Hongsheng produce a lot of ball valves – this is just for reference
Basic process parameters and usage control requirements must not be compromised!
For your operating conditions, any domestic product will do. It all depends on the sealing level
