Ammonia flow limiting valve

    Dateline:2014-11-30    Hits:

    This valve is a safety protective valve, used in ammonia, liquid ammonia, oil and othernon corrosive medium. In the media in the pipeline flow rate exceeds the set value is too large to shut immediately, automatically shut down in the pipeline or attachments corrupted velocity, preventing the occurrence and expansion of the accident, usually installed in the tank or pipe export, import and export, the safety and reliability ofprotect downstream equipment. The driving means can be automatically connecting mode can be selected, flange, the structure can be used for current limiting type, the sealing structure can use soft seal, seal, pressure PN0.1-4.0Mpa, nominal diameter is DN25-200mm, the use of cast iron, cast steel materials, stainless steel. Due to the use of the scope of the valve is very wide, with a valve has different collocation in theoccasion with different conditions, if you are a non professional, welcome you to the company to inquire. The company has professional technical staff to serve you!
