Product Description

Product description:
1.Compact structure, reasonable design, good valve rigidity, smooth passage and small flow negative coefficient
2.The sealing surface is made of stainless steel and cemented carbide, which has long service life
3.Adopt flexible graphite packing, reliable sealing, light and flexible operation
4.Driving mode: manual, electric and pneumatic gear transmission
5.Structure form: elastic wedge single gate, rigid wedge single gate and double gate
6.Widely used in petrochemical industry, thermal power plants and other oil products, water vapor pipeline as an opening and closing device to connect or cut off the medium in the pipeline

Features

1. Using austenitic stainless steel, it has good corrosion resistance to oxidizing acid media.

2. When the medium flows through the stainless steel gate valve, its flow direction is not changed, and the fluid resistance is small.

3. The movement direction of the gate is perpendicular to the flow direction of the medium, the opening and closing moment is small, and the opening and closing is labor-saving.

4. The flow direction of the medium is not restricted, does not disturb the flow, and does not reduce the pressure. The medium can flow in any direction from both sides of the gate valve and can achieve the purpose of use. It is most suitable for pipelines where the flow direction of the medium may change.

5. The gate is vertically placed in the valve body and the structure length is short.

6. Good sealing performance. The sealing surface is less eroded when fully opened.
