China Gate Valve-DIN 3202 Gate Valve Use】

China Gate Valve-DIN 3202 Gate Valve is suitable for cutting or connecting pipeline media in pipelines of various working conditions such as petroleum, chemical and thermal power plants with ANSI Class 150~2500 and working temperature <600°C. Applicable medium: water, oil, steam, etc.

[DIN 3202 Gate Valve Features:]

1. Product design and manufacture According to API standard, the seal is reliable, the performance is excellent, and it can be used with imported equipment.

2, 600Lb above the gate and valve seat seal is made of stellite cobalt-based hard alloy surfacing, wear-resistant, high temperature resistance, corrosion resistance, good scratch resistance and long service life.

3. The valve stem is quenched and tempered and surface nitrided, which has good corrosion resistance and scratch resistance.

4, the use of wedge-type elastic ram structure, medium and large diameter set of rolling bearings, easy to open and close.

5, the valve body material is complete, the packing and gasket are reasonably matched according to the actual working conditions or user requirements, and can be applied to various pressure, temperature and medium working conditions.

6, 1500LB, 2500LB medium cavity uses a pressure self-tightening sealing structure. The sealing performance increases as the internal pressure increases, and the reliability is high.

7. The inverted seal is made of stainless steel threaded joint sealing seat or body surfacing austenitic stainless steel. The reverse sealing is reliable. The replacement and maintenance of the packing can be carried out without stopping the machine. It is convenient and fast without affecting the system operation.
