1, the use of high temperature: under the condition of strong corrosive medium, can meet the use of temperature range -60℃ ~ 200℃, in this temperature range (in addition to molten alkali metals, elemental fluorine and aromatic hydrocarbons), can meet all chemical media.

2, vacuum resistance: in the range of -60℃ ~ 150℃, can be used in vacuum conditions, in chemical production, often due to cooling, longitudinal discharge, pump valve is not synchronous operation of the local vacuum state.

3, high pressure resistance: in the range of temperature, can withstand up to 3Mpa use pressure.

4, anti-permeability: the selection of high quality resin, through the advanced lining process into high density, enough thickness of PTFE lining layer, so that the product has superior permeability resistance.

5, the integral molding sintering process lining, solved the problem of steel - fluorine hot and cold expansion, so that it can achieve synchronous expansion.

6, the use of standardized size preparation, especially the chemical pipeline used in the pipeline, pipe fittings have a strong interchangeability, for the installation of spare parts to provide great convenience.
