Dual plate check valve with retainless and dual plate check valve is a very similar, the difference is whether there is a retainer
The retainerless design with dual disc check valve also provides higher integrity on high pressure, ensuring no concerns about body’s leakage.
The retainerless body is realized in cast steel, carefully designed in order to minimize the pressure drop. The basic dimensions, wall thickness, face to face and flanges, comply with the relevant API and ASME standards.
The check or non‐return valve is most commonly used in pumping stations and allows the flow in only one direction thus preventing back flow when the fluid in the line reverses direction.
The main importance of this function is twofold:
1) To prevent damage to upstream equipment that can be affected by reverse flows such as pumps and measuring equipment.
2) To prevent reverse flow after system shutdown or water hammer.
10. In a wafer connection the valve is installed between the pipe flanges and tightened to its place with the bolts for the pipe flanges.
Wafer type body is the lightest body version for mounting between piping flanges. Therefore a wafer valve use to be cheaper than other valves. Also it is fast mounting.
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.

- Pressure Rating For ASME: 125# ~ 2500# Suit For ASME / MSS / API Flange
- Pressure Rating For ISO: PN10 ~ PN40 Suit For ISO Flange
- Pressure Rating For JIS: 5K ~ 20K Suit For JIS Flange
- Material:CI,DI,WCB,CF8,CF8M,ALBC3,A8904A(MOQ)
- Designed in accordance with API 594
- End Connection: Wafer, Lugged (TC8-2, TC8-3), Flanged (TC8-1)
- *Technical information is only for reference. Taiwan Valves Centre Co., Ltd. reserves the right to change without previous notice.
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:
WCB - This steel has a good welding characteristic, suitable for use in the environment needs seat overlay welding.
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.
