Backflow can cause an issue if the backflow is contaminated, and therefore, contaminates the media upstream. For example, a sewer line will have a non return valve to ensure that waste can leave but not re-enter the system. They are also used if backflow will cause damage to equipment upstream that can only allow media to flow in one direction. For example, a reverse osmosis filter can only have water pass through it in one direction, so a one way valve is installed downstream to prevent this. There are various sizes, designs, and material to ensure there is a check valve for every application.Dual plate check valve are available in 4 basic connection: Wafer, Lug, Solid Lug, Flanged end, and in an extensive range of sizes, pressure classes and materials. Material required other than standard upon request
The retainless design means that they do not drill completely through the body of the valve to enable installation of the hinge-pin and stop-pin of a dual-plate check. Instead of drilling through, they machine out a recess.
Features
- High expansion coefficient, high temperature, and high pressure resistance.
- Suitable for use in high temperature environments, replacing the retainer with a carrier design to avoid abnormal leakage caused by high temperature.
- The appearance of the product is more beautiful than the general type
- Compared with the general type, the retainerless type without retainer is easier to disassemble, and faster and easier maintenance.
- Retainerless duo check Valves do not have any leakage problem on Body. Wafer type design fastens valve by bolt and flanges. Retainerless duo check Valves are clamped between mating flanges which are connected by bolt and nuts.

Applications
- Retainerless dual check valve is suitable for high temperature and high pressure environment, like Petrochemical, Refinery or power plant.
- Use for any industry concerned with fire hazards or environmental safety
- Suitable for use in clean, dirty and sea water applications.
- Also use for gases like Chlorine, Hydrogen, Nitrogen, Carbon Dioxide (Co ), Oxygen etc.
- Retainerless type check valve can be installed in heating air-conditioning pipe lines.
- Installed in hydrocarbon and chemical processing.
- Retainerless Duo check Valve also can be used in steam/vapor applications.
- Retainerless dual check valve is a preferable option for highly toxic, corrosive, or hazardous gas chemical processing applications.
- Applied in Iron and steel industry.
More Knowledge about TVCCL valve:
TVCCL Retainerless wafer check valve body features a single cast body without penetration through the body wall, eliminating the possibility of outside leakage; making it a preferable option for High-temperature work environment. Under the normal using situation, TVCCL guarantee retainerless type valve does not have any leakage problem on Body. Dual plate check valve with retainerless are available in 4 basic types: Wafer, Lug, Solid Lug, Flanged end, and in an extensive range of sizes, pressure classes and materials.
TVCCL check valve made of selected materials, each valve we made can offer the material certificate which according to BS EN 10204 3.1. Under the normal using situation, we can guarantee the TVCCL valve is more durable than the other manufacturers. And the performance is more reliable and practical. Using check valve under normal situation all can achieve the non-return effect. However, if the pipeline installation distance is less than 6~8 times the size of the valve, the life of the check valve may be shortened or the valve body and parts may be damaged.
More Knowledge about dual plate check valve:
CF8.CF8M - literally, "stainless steel" is the steel rusty hardly. Stainless steel is used where both the properties of steel and corrosion resistance are required.
Stainless Steel are devided into many serials. Most commonly are A351 CF8,A351 CF8M,A351 CF3M…etc.
The Retainerless type is a type which body without pin retainer holes in the body. Retainerless type check valve use carrier and screw instead of retainer function to fix the pin. This design minimizes prospective leak paths through the valve body making it a preferable option for highly toxic, corrosive, or hazardous gas chemical processing applications. Retainerless valves are also suitable for high-temperature liquid, natural gas, steam service applications. Retainerless type check valve all inserts/parts are all the same as Dual plate check valve, except for using carrier and screw to replace the retainer. Simply, Dual plate check valve is drill four holes through the body of the check valve to facilitate installation of a hinge pin and stop pin, but Retainerless can be fixed by carrier and screw and is no need to drill the holes outside of valve’s body. Model: TC8 Wafer or Double Door Check Valves have no through holes. The Retainerless special to use in industry, especially offshore or onshore pipelines, there is a tremendous concern for fugitive emissions and potential environmental concerns. Retainerless check valve design also provides higher integrity on high pressure, ensuring no concerns about leakage.
