Product Description

The tungsten carbide flat valve seat has a flat bottom, and the sealing surface is parallel to the valve disc. Suitable for low-pressure, low-temperature, small-diameter gate valves. The flat valve seat is the core component that controls the sealing performance of the valve, affecting the sealing effect and service life of the valve. The cemented carbide valve seat, mainly composed of tungsten carbide and metallic cobalt powder, which can provide better physical properties and longer service life for key sealing components such as valves. Therefore, they play a key role in fields such as oil and gas, chemical processes, etc.

Tungsten carbide valve seats are one of our main products. According to research, the use of TC valve seats can extend the service life of valves by 3-5 times.

Features

Tungsten carbide flat valve seats have their specific operating conditions. Therefore, when choosing, customers should fully consider the situation of their own equipment;
Due to the material of cemented carbide, compared to other raw materials, flat valve seats can have higher hardness, density, compressive strength, corrosion resistance, etc. This not only improves the sealing performance of the valve itself, but also greatly extends its service life, reducing economic losses caused by equipment maintenance;
As a customized factory, our customized products are not only related to the size and geometric shape of the products. Meanwhile, we can innovate in materials. Such as adding layers or adding anti-corrosion metal raw materials.
In addition to strict control of raw material quality, in precision machining production lines, the surface roughness and tolerances can be tightly controlled to ensure sealing and throttling effects with the gaps between specific mating parts.
