1.Fully sulfur resistant materials and certification
The core components such as valve body, valve cover, valve disc, valve stem, and spring are made of NACE certified sulfur resistant materials (such as F316, Monel, Inconel 625, etc.) and undergo stress relief heat treatment to ensure long-term safe operation in wet H ₂ S environments.
2.Full opening large displacement discharge
Adopting a fully open structure, the valve disc has a large opening height, a large discharge area, and strong discharge capacity (displacement). It is suitable for situations that require rapid and large pressure relief, such as acidic natural gas, steam, or process gases.
3.Hard alloy seal ("Y" type)
Sealing surface welding with high-performance hard alloys such as Stellite has extremely high hardness, wear resistance, high temperature resistance, and excellent acid corrosion resistance.
4.Spring sulfur resistance and stability design
The spring material and surface protective coating both consider the requirements of sulfur resistance and hydrogen embrittlement prevention, ensuring long-term stability of elasticity and accurate and reliable setting pressure.
5.Strict leakage control and safety
In response to the toxicity and danger of acidic media, valves pursue higher sealing levels to minimize the risk of leakage as much as possible.
