Product Description

 

features
• It's serviced in the circumstance where the heat preservation of fluid is needed, such as the equipment of polyester, ethylene, urea, etc.
• Body including inlet and outlet flanges is heat preserved, so the effect is very well. The function of vapor flushing can be added, if needed.
• Balanced bellows construction protects set pressure from being affected by variable back pressure, and the parts in bonnet, such as spring, from being corroded.
The standard materials for the inside parts (Valve clack, valve seat) are all austenitic stainless steel and bead welding cobalt-base ha- rd alloy.
• To meet special service, the material oftrim can be 316LN,0Cr25Ni6Mo3CuN (255 alloy) and 00Cr25Ni6Mo2N (SUS329J1) ,the material of bellows can be Ti.




Spring Loaded Full Bore Type with Lever Safety Valve is used for the equipment and pipeline of steam and air etc medium what the working temperature are less than 350. A44Y type are used for the equi-pment and pipeline of the with air and petroleum gas medium what the working temperature are less than 300, Take for extra pre-ssure protection devices. Flange connecting dimensions of comply with Standard series first of JB/T-94 when the pressure less than 6.4MPa, comply with Standard series two of JB/T-94 when more than 6.4MPa.
