Benefits Of Stainless steel 304 thread type full opening safety valve:
A28H type safety valve are used for the equipment and pipeline of the air, N2,H2 mixed gas vapour etc. medium what the working temperature are less than 200℃.A28Y-P/R type are used for the equipment and pipeline of the quality with corrode medium what the working temperature are less than 200C.Take for extra pressure protedtion devices.
Features Of Stainless steel 304 thread type full opening safety valve :
1). Simple structure, good sealing performance, and accurate opening pressure
2). High discharge capacity, small reseating pressure difference, and easy adjustment
3).The valve body is typically made of SS304 or WCB cast steel.
4).For systems with a nominal pressure of ≤ 1.6 MPa and a working temperature of ≤ 200℃, for media such as air, steam, water, etc.
