Product Description

Product Specifications
Valve Type: Swing check valve Structure: Swing type
Standard: API609 Workmanship: Investment casting
Sealing direction: Single-directional Sealing grade: Zero leakage
Temperature: -40°C < T < 800°C Operation: Self-starting
Material Characteristics
Core components such as valve body, valve disc, rocker, etc. are preferably made of 304 stainless steel, 316 stainless steel, 316L stainless steel, or duplex stainless steel materials.
Characteristics
Core Advantages
1. Excellent Corrosion Resistance
The dense passivation film formed on the surface can resist the erosion of weak acids, weak bases, salt spray, seawater, and organic solvents. Compared with cast iron and cast steel valves, it can effectively avoid problems such as valve body corrosion and medium pollution.
2. High Strength & High Temperature Resistance
The tensile strength of stainless steel material is ≥ 520MPa, and its mechanical properties are stable in the temperature range of -40℃~600℃. It can withstand the impact of high-pressure media and long-term erosion of high-temperature media.
3. Sanitary Adaptability
316L stainless steel and other materials have high surface smoothness, no pores, and do not adsorb impurities, meeting the hygiene standards of industries such as food, pharmaceuticals, and drinking water.
Advantage Detail
Packaging & Delivery
Standard export wooden case packaging
Packing
Application Scenarios
Widely used in pipeline systems in industries such as chemical, petroleum refining, marine engineering, pharmaceuticals, food and beverage, electricity, water treatment, etc., it is particularly suitable for conveying corrosive media, high-temperature and high-pressure media, and clean fluids.
