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.
