Product Description

FEP/PTFE/PFA Lined Safety Valve/Hastalloy C Material Safety Valve

Product Description

FEP/PTFE/PFA Lined Safety Valve/Hastalloy C Material Safety Valve Description
PFA Lined Safety Relief Valve, developed according to domestic and foreign advanced technology, can be used in chlor-alkali Chemical industry, hydrochloric acid,  sulfuric acid and other high-risk corrosive medium. It can act as overpressure protection device to protect system security on the pressure equipment and pressure contrainer. This valve adopts PTFE Bellows seal which has anti-leakage function. Inner cavity of the valve body is fully lined with PFA or FEP ( F46) with more than 2.5mm thickness.
