Check Valves

Check valves for fluids are a type of valves which allow fluids to flow in one direction, but automatically close when the flow reverses. They are also called non-return valves or one-way valves. They can prevent the backflow securely and open with small differential pressure. They are applied to piping systems where the backflow prevention is required, frequent open/close are expected, some restrictions exist around the pipings, etc. To install, there are screw-in connection type to screw in the check valve, and flangeless type that clamps the entire check valve with pipes. Furthermore, they are divided into small diameter valves or large diameter valves. Materials of the main body are copper alloy, stainless steel, fluoropolymer, plastic, etc. Sealing materials vary depending on the application; metal is used for places where the temperature becomes high due to steam, etc., and rubber is for places under low temperatures such as hot or cold water.

    CS-3SSN, Check Valve (for Cold Water / Hot Water)

    CS-3SSN, Check Valve (for Cold Water / Hot Water)

    VENN

    Spring-type for apartment buildings, houses, building facilities, etc. (low pressure loss, prevents water hammer)

    [Features]
    · For various water supply systems; prevents backflow using back pressure when the pressure of the supply water source decreases due to water supply cutoff, and for maintenance of a reliable and safe water supply.
    · Spring style with a closing valve for back-flow prevention during a water outage; prevents water hammering, delivering excellent safety.
    · Valve body includes a synthetic rubber disk.
    · Usable with warm water up to 90°C.
    · Water can be supplied with low pressure loss.
    · Pipe end cores are used for connectors, as they are made of material that will not rust, thus preventing rust-colored water.
    · The valve body employs a cartridge structure for easy maintenance.
    · Noise is kept to 40 dB or below (at rated flow rate) while water is flowing, roughly the same level of noise produced by standard pipes.
