4\" NPT Horizontal Swing Check Valve, Brass, Heavy-Duty Female Thread, DN100 For Sale

Product description SYWUWV BRASS NPT HORIZONTAL CHECK VALVE

SYWUWV BRASS NPT 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.

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. THICKENED VALVE BODY

The valve body is brass, which is anti-pressure, anti-explosion, uniform wall thickness, abrasion resistance, high strength, high temperature resistance and durability.

SMOOTH INNER WALL

The check valve is polished and smooth inside, which is not easily scaled and not clogged.

NPT THREAD

Standard NPT threads, clear threads, no water leakage.

1. Difference material

(1) The brass horizontal check valve is mainly made of brass.

(2) The stainless steel horizontal check valve is made of stainless steel.

2. Different application scenarios

(1) 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.

(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.

• ONE-WAY FLOW CONTROL – This Horizontal Swing Check Valve prevents backflow by allowing media to flow in only one direction, helping to protect pumps and piping systems from reverse flow disruption. Features smooth flow path for low pressure drop during operation.
• DURABLE SWING CONSTRUCTION – The horizontal swing-type disc mechanism ensures smooth and reliable valve closure, minimizing water hammer. Heavy-duty brass body with uniform wall thickness delivers reliable performance under pressure for long-term use.
• SMOOTH INTERNAL FINISH – Polished inner wall helps minimize scaling and clogging, supporting consistent flow performance and easier maintenance. The horizontal swing check valve design reduces wear on internal components for extended service life.
• VERSATILE APPLICATION – Available in multiple sizes for residential, commercial, and industrial piping systems. Designed exclusively for horizontal installation (flow parallel to pipe). Suitable for water, oil, and non-corrosive gas pipelines.
• TECHNICAL SPECIFICATIONS – Maximum working pressure: 1.6 MPa (232 psi). Temperature range: -20°C to 150°C (-4°F to 302°F). Media: water, oil, non-corrosive gases. Select proper size according to specification chart.
