PFA Lined Pressure Relief Safety Valve

Lined safety valve is  developed according to use the domestic and foreign advanced technology. This valve is used in the chlor-alkali chemical industry, hydrochloric acid, sulfuric acid and other high-risk corrosive medium, protects system security on the pressure equipment and pressure container. The valve uses PTFE bellows seal that has anti-leakage function. Inner cavity of the valve body is fully PFA or F46 lined more than 2.5 mm thickness. 

All components of YFM safety valves are made with
PTFE-lined materials, including the permanently medium wet-
ted inlet area composed of a nozzle and a disc, the additional
protection of the bonnet area by means of a bellows and all
components of the inlet and outlet areas.
• Designed and manufactured according to the highest stan-
dards
• Reach their full lift within a pressure increase of 10% above
the set pressure
• Are characterised by longstanding proof in service.
• Are developed and optimised in close cooperation with plant
engineers and service specialists to protect processes with
highly corrosive and toxic media.
• Meet the highest requirements of end customers, OEMs and
planners.
• Are approved by all important classification societies world-
wide. This ensures the worldwide applicability of YFM safety valve
