Q. What Kind Of Material We Stock For Dual Check Valve?
TVCCL has been designing & manufacturing dual plate check valves since 1998. We equipped with the required basic material to arrive at an optimum product delivery to meet all our customer requirements.
TVCCL holds ready dual plate check valves stocks for smaller sizes enabling us to respond quickly to requests for customer’s quick need. Also, all TVCCL wafer type check valve and materials are fully traceable and certified.
For dual check valve WCB/CF8/CF8M/CI/DI/B148 C95800(ALBC3) we usually have stock as above; However, to some special materials, like A8904A/CF3M…etc. We need evaluate if it need MOQ or not.
Seat of dual plate wafer type chack valve we normal have as bellow
NBR→Usually used in WATER & WASTEWATER TREATMENT.
EPDM→Usually used in OIL & GAS.
VITON→Usually used in CHEMICAL & PETROCHEMICAL.
METAL (Same as Body)→Usually used in HIGH TEMPERATURE ENVIRONMENT, HAVE LEAKAGE.
※Rubber seat zero leakage
Metal seat leakage permitted values according to standard API598, permitted value is “size*700c.c”/Min
Otherwise, we have special type named “__________”
Under no pressure environment, no leaking when you pouring water into valve.

Dual plate wafer type check valve with full rubber is usually used in seawater desalination system. Usually we chose iron body and aluminum bronze disc to complete the valve. Dual plate wafer type check valve with full rubber don’t need MOQ. Dual plate wafer type check valve with full rubber can applied in the sewage industry, sea water treatment and desalinization project, and etc.
Full rubber body dual plate flange check valves design with no external body penetrations eliminating the possibility of outside leakage. Because the body design with full rubber lined The elevated costs and continuous variation in the prices of prime materials used for castings of alloyed materials for corrosion resistance is motivation to look for alternatives more economical or other type of constructions. Dual plate flange type check valve with full rubber is good choose. By this application costs can be reduced between 15% and 35% of the total valve cost compared with the body completely in alloy.
Lug type dual plate with full rubber lined check valve's body with full rubber lined can effectively reduce disc's leakage probability for the corrosion of seawater. In a lugged connection the valve is fastened directly to the pipe flange by connecting the pipe flange with bolts to the valve body also drilled with threads. Small space available, easier installation, Quick closed to reduce water hammer situation. Cost Efficient, the cost would be less than swing type check valves, with the same functional operation.
Full Lug type dual plate check valve is suitable for the environment where the space is small, because the flange hole has tapping, it can save the space occupied by the nut and the cost of the nut. Versus conventional swing check valves, the series valve have the advantages of no leakage toward outside API 594 dual plate check valve is widely used in the flow control industry. Due to its short face to face dimension, it requires smaller installation space and has lower weight, which offers competitive life cycles costs compare with swing check valve.
