Description

Functional Parameters

• Nominal Pressure: Although not explicitly stated in the product description, stainless steel 304 and 316 gate valves can typically withstand various nominal pressures, such as 1.0 MPa, 1.6 MPa, and 2.5 MPa. The specific pressure rating depends on the valve’s design and manufacturing standards. A higher nominal pressure indicates that the valve can operate safely and reliably under higher pipeline pressures, effectively preventing media leakage.

• Applicable Temperature Range: Stainless steel 304 gate valves generally function within a temperature range of -20°C to 300°C. Due to its superior performance, stainless steel 316 can withstand a wider range, typically from -40°C to 400°C. However, the actual temperature resistance also depends on factors such as the valve’s sealing material.

• Sealing Performance: Effective sealing is essential for gate valve performance. High-quality valves should feature a reliable sealing structure to prevent fluid leakage when closed. Common sealing materials include rubber and polytetrafluoroethylene (PTFE), each suitable for different media and operating conditions, ensuring optimal sealing efficiency and durability.

• Flow Capacity: Thanks to the gate valve’s design, when fully open, fluid can flow through with minimal resistance, resulting in high flow capacity. This makes DN100, 14-inch, and 12-inch gate valves ideal for handling large-flow media in pipelines of corresponding diameters.

• Media Compatibility: Stainless steel 304 gate valves are suitable for water, air, steam, and other general media. Stainless steel 316, with its superior corrosion resistance, is better suited for chloride-containing solutions, acidic or alkaline media, and other corrosive substances. However, media compatibility should always be evaluated based on the actual composition and concentration of the fluid being transported.
