GV410 GV410 Acid Resistant Bellows Control Valve

Acid resistant bellows control valve is an execution unit in the automatic apparatus system. It is installed in the medium conveying pipeline with other instruments to control the fluid flow. The valve part that is in contact with the medium are processed with high-pressure injection molding, corrosion resistance, aging resistance of poly fluorinated ethylene propylene (F46).
And it also applied with PTFE bellows seal which contribute to a reliable sealing performance despite the unique advantage of acid and alkali resistance (hydrochloric acid, sulfuric acid, hydrofluoric acid). The valve is suitable for controlling medium with strong acid, strong alkali, volatile, easy penetration, so it is widely applied in industrial automation device with special media control system, including chemical, petroleum, metallurgy, medicine, textile etc.

Features

1, With double sealing characteristics of PTFE bellows seal and V type PTFE packing seal, to prevent medium leakage

2, The lining material F46 and PFA can be used to get the maximum temperature resistance of 140 and 200 degrees Celsius

3, Hastelloy alloy plug, valve stem and valve seat can be used to ensure valve service life in case that the valve plug and valve seat lined with material F45/PFA is not able to meet the required hardness in occasions of flash and cavitation

Benefits   

1, Corrosion resistance - body cavity, valve plug, valve seat, valve stem are all lined with material F46 or PFA in thickness of 2.5 - 3mm to resist acid, alkali and strong corrosion.

2, Small leakage - the leakage is lower than national level IV standards due to the soft seal of plug and seat.

3, Small and multi-spring actuator, small size, light weight and high precision adjustment
