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.

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. ## Features - ONE WAY FLOW CONTROL -- It is a kind of valve that relies on the pressure of the medium to produce the effect of preventing the backflow of the medium. Only allows the medium to flow in one direction, to prevent the medium backflow. - EXPLOSION-PROOF & WEAR-RESISTANT -- The valve body is characterized by pressure, explosion resistance and durability... It has uniform wall thickness, high wear-resistant strength and long service life. - SUPERB CRAFTSMANSHIP -- The brass check valve inner wall polishing treatment, smooth surface, no scaling, no clogging, practical and durable. - WIDE RANGE OF USES -- A variety of specifications are available for most piping systems. Widely used in chemical, construction, petroleum, light and heavy industry, fire fighting, electric power, aerospace, shipbuilding ... - INSTRUCTION -- Maximum working pressure: 1.6 MPa / 232.06 psi. Applicable temperature: FROM -20℃ TO +150℃（FROM -4℉ TO 302℉）, Flow direction: unidirectional, media range: water, oil, non-corrosive flammable gas. Please select the appropriate size horizontal check valve according to the size chart. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CH135XCF | | Best Sellers Rank | #24,465 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #30 in Check Valves | | Brand | SYWUWV | | Brand Name | SYWUWV | | Customer Reviews | 4.6 out of 5 stars 122 Reviews | | Exterior Finish | Brass | | Inlet Connection Size | 1 Inches | | Inlet Connection Type | National Pipe Tapered | | Manufacturer | SYWUWV | | Manufacturer Part Number | 1 | | Material | Brass | | Material Type | Brass | | Maximum Pressure | 1600000 Pascal | | Model Number | 1 | | Number of Ports | 1 | | Outlet Connection Size | 1 Inches | | Outlet Connection Type | NPT thread | | Size | 1 Inch | | Thread Size | 1 inch | | Thread Type | NPT | | Unit Count | 1.0 Count | | Valve Type | Swing Check Valve | ## Product Details - **Brand:** SYWUWV - **Exterior Finish:** Brass - **Inlet Connection Size:** 1 Inches - **Inlet Connection Type:** National Pipe Tapered - **Manufacturer:** SYWUWV - **Material:** Brass - **Maximum Operating Pressure:** 1600000 Pascal - **Number of Ports:** 1 - **Outlet Connection Size:** 1 Inches - **Outlet Connection Type:** NPT thread ## Images ![1" NPT Horizontal Check Valve, Brass Non Return Swing Check Valve to Prevent Water Backflow, Level One Way Counterflow Valve to Prevent the Medium Backflow for Oil Water Gas Air（1", DN25） - Image 1](https://m.media-amazon.com/images/I/717Hc6MB+CL.jpg) ![1" NPT Horizontal Check Valve, Brass Non Return Swing Check Valve to Prevent Water Backflow, Level One Way Counterflow Valve to Prevent the Medium Backflow for Oil Water Gas Air（1", DN25） - Image 2](https://m.media-amazon.com/images/I/71Eam2bCTgL.jpg) ![1" NPT Horizontal Check Valve, Brass Non Return Swing Check Valve to Prevent Water Backflow, Level One Way Counterflow Valve to Prevent the Medium Backflow for Oil Water Gas Air（1", DN25） - Image 3](https://m.media-amazon.com/images/I/616iyaHxUDL.jpg) ![1" NPT Horizontal Check Valve, Brass Non Return Swing Check Valve to Prevent Water Backflow, Level One Way Counterflow Valve to Prevent the Medium Backflow for Oil Water Gas Air（1", DN25） - Image 4](https://m.media-amazon.com/images/I/71tv+fT0QJL.jpg) ![1" NPT Horizontal Check Valve, Brass Non Return Swing Check Valve to Prevent Water Backflow, Level One Way Counterflow Valve to Prevent the Medium Backflow for Oil Water Gas Air（1", DN25） - Image 5](https://m.media-amazon.com/images/I/81IOUeyvK5L.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by J***H on February 22, 2026* ### ⭐⭐⭐⭐⭐ Review *by D***. on November 5, 2024* ### ⭐⭐⭐⭐⭐ Review *by B***N on February 18, 2026* ## Frequently Bought Together - 1" NPT Horizontal Check Valve, Brass Non Return Swing Check Valve to Prevent Water Backflow, Level One Way Counterflow Valve to Prevent the Medium Backflow for Oil Water Gas Air（1", DN25） - 2PCS Brass Nipple Fitting 1" x 1" NPT Male Hex Adapter by CX WONDERLAND - Anderson Metals 38101 Red Brass Pipe Fitting, Tee, 1" x 1" x 1" Female Pipe --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/588147779-1-npt-horizontal-check-valve-brass-non-return-swing-check](https://www.desertcart.jp/products/588147779-1-npt-horizontal-check-valve-brass-non-return-swing-check) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-05-05*
