4" NPT Horizontal Check Valve - Stainless Steel Non-Return Swing Check Valve for Oil, Water, Gas & Air (DN100) | Prevents Backflow in Piping Systems | Ideal for Industrial, Plumbing & HVAC Applications

Product Description

SYWUWV NPT STAINLESS STEEL HORIZONTAL CHECK VALVE SYWUWV NPT STAINLESS STEEL HORIZONTAL CHECK VALVE is a safety valve used to control the flow of fluids in pipelines to prevent backflow and leakage. It is commonly used in wastewater treatment, chemical, food processing, petrochemical and other industries. And it is used with a wide variety of fluids including, but notlimited to water, oil, gas, air, biodiesel, and fuels. PRINCIPLE OF CHECK VALVE When the fluid in the forward movement process, the valve flap by the fluid pressure will be pushed open, the fluid will be smooth through the pipeline into the next process. However, when the fluid flows in the reverse direction, the valve flap and the valve seat closely fit, preventing the reverse flow of the medium and leakage. CHECK VALVE WORKFLOW When the check valve is in normal working condition, the valve flap is in the open state, and the fluid can flow through unhindered. When the fluid flows in the reverse direction, the valve flap closes quickly, avoiding the backflow of fluid and preventing the leakage of the medium in the pipeline, which ensures the safety and stability of the pipeline to the environment. The products are widely used in industries. HOUSE WATER AND HEATING SYSTEM PETROLEUM INDUSTRY NATURAL GAS INDUSTRY FOOD INDUSTRY PAPERMAKING INDUSTRY PHARMACEUTICALS INDUSTRY CHEMICAL INDUSTRY SHIPBUILDING INDUSTRY SYWUWV Our company is an enterprise that integrates scientific research, manufacturing, and sales of various valves. Main products: quick connectors, vent valves, ball valves, pneumatic angle seat valves, pneumatic valves, gate valves, globe valves, check valves, three-way ball valves, butterfly valves, high-pressure pipe fittings, fluorine lined valves, and so on. The product materials include brass, carbon steel, stainless steel, and alloy steel. SMOOTH INNER WALL The check valve is polished and smooth inside, which is not easily scaled and not clogged. THICKENED VALVE BODY The valve body is stainless steel, which is anti-pressure, anti-explosion, uniform wall thickness, abrasion resistance, high strength, high temperature resistance and durability. NPT THREAD Standard NPT threads, clear threads, no water leakage. 1. Difference material (1) The stainless steel horizontal check valve is made of stainless steel. (2) The brass horizontal check valve is mainly made of brass. 2. Different application scenarios (1) Application Scenarios of stainless steel horizontal check valve -- The stainless steel horizontal check valve is widely used in the chemical, petroleum and food industries because stainless steel has good corrosion resistance and high strength properties. At the same time, because stainless steel will not be worn out by repeated use, making it widely used in the aviation and marine fields. (2) Application Scenarios of brass horizontal check valve -- Because brass has good thermal and electrical conductivity, the brass horizontal check valve is widely used in hot and cold water piping, water supply piping, and fire protection systems and so on.
