High Discharge Relief PFA Safety Valve Coefficient Bellows Style PTFE Lined

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
