Stainless Steel Sanitary Thread NRV Non Return Check Valve
The purpose of the stainless steel sanitary threaded check valve is to ensure that the fluid can only flow in one direction and prevent backflow from contaminating the pipeline system or equipment. It is designed to protect the system from damage and contamination caused by backflow, especially in the food, pharmaceutical, chemical and other industries, to ensure the sanitary safety of the fluid transmission process and the long-term stable operation of the equipment. At the same time, the design takes into account the convenience of cleaning and maintenance, and meets high standards of hygiene requirements.
Working Principles
The working principle of the stainless steel sanitary threaded check valve is to control the flow direction of the fluid through the valve disc. When the fluid flows in the correct direction, the valve disc opens to allow the fluid to pass; when the fluid flows back, the valve disc closes to prevent backflow and protect the system safety. Using a stainless steel sanitary threaded check valve can effectively prevent fluid backflow and protect the pipeline system from contamination and damage. It ensures that the fluid passes smoothly when it flows in one direction, avoids the negative impact of backflow on equipment and pipelines, and maintains system pressure stability.
The options for stainless steel sanitary threaded check valves include:
Material selection: 304, 316L stainless steel, adapted to different environments and hygiene requirements.
Sealing materials: EPDM, Viton and other different types of sealing rings, adapted to different fluid and temperature requirements.
Connection method: Threaded connection, different thread types (such as NPT, BSP, etc.) can be selected according to pipeline standards.
Valve disc type: including spring-loaded valve discs and gravity valve discs, etc., adapted to different working pressures and fluid types.
Size specifications: Different pipeline sizes and interface specifications can be provided according to customer needs.
Pressure level: Applicable to different working pressure ranges, select the appropriate pressure level to ensure safe use.

Features
● The stainless steel sanitary threaded check valve adopts a threaded connection method, which is convenient for quick connection with the pipeline system.
● The stainless steel sanitary threaded check valve is designed to ensure that the fluid can only flow in one direction to prevent backflow.
● The stainless steel sanitary threaded check valve adopts high-performance sealing materials, which has strong sealing and ensures no leakage.
● The stainless steel sanitary threaded check valve design has a certain seismic resistance and can withstand mechanical vibration.
● When the fluid passes through the internal channel of the stainless steel sanitary threaded check valve, the friction resistance is low and the flow is smoother.
● The stainless steel sanitary threaded check valve has a simple structure and no complex parts inside, which is easy to disassemble and clean.
Application
Stainless steel sanitary threaded check valves are widely used in the following industries: Food and beverage: Ensure that the fluid is not contaminated and meet hygiene requirements. Pharmaceuticals: Control the flow direction of the fluid to avoid contamination and meet GMP standards. Chemicals: Used for fluid control in highly corrosive, strong acid and alkali environments. Bioengineering: Ensure the flow of high-purity liquids and system stability. Dairy products: Ensure the hygiene and safety of the fluid and avoid backflow pollution. Water treatment: Prevent water backflow and maintain system pressure stability.
