About this item

  • 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.

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.

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.

Solid construction, well-machined, priced right. Works as described/expected. My application is in a low pressure hydronic loop to prevent backflow.

This is a cheap check valve, the original one held water pressure no problem, this one will not hold 60 psi of water pressure. It continuously leaks past the check valve…

If you have decent flow to ram pump (4gpm), and 3ft of head, this is a great check valve for you. It is well built with smooth insides to help prevent mineral accumulation. Threads are true NPT. And the price is very good (less than 15 dollars for 1 inch brass check valve.)If you have low input flow, this valve might be too heavy for your ram pump.

I needed this to repair an issue with my rural well. The old valve was leaking and a replacement was not available at the Blue or Orange stores locally.The casting/machining and threads are very clean. The valve works properly and I have no concerns about it's longevity... Great price too!
