productspipe fittings, valves, aseptic diaphragm valves, aseptic tank bottom valves and other high-end products
productspipe fittings, valves, aseptic diaphragm valves, aseptic tank bottom valves and other high-end products
can be applied in food,beverage,brewing,dairy,water treatment, pharmaceutical and chemical industries,with an intended purpose of controlling the
flow of fluids with viscous or particulate matters in pipelines or pressure vessels.
blow-out proof stem adds safety and reliability to the full extent.
thickened stem packing ;v-shaped stacking design;adjustable self-compensating gland.
multiple control modes.easy to realize remote or automatic control.
seal material：
1.standard ptfe seals are compatible with most operating conditions(-10~ 110℃)
2.tfm600 seal is also available as an option,which is also compatible with many operating conditions(-60~ 150℃)
3.pob seal is also available for high-temperatures operating conditions(-10~ 210℃)
4.in the range of its specified working pressures and temperatures,the valve is perfectly sealed.when pressure increases,the sealing performance can automatically be
improved.due to a small friction between seals and valve body,the stem torque is also relatively small.
