Stainless Steel Dual Plate Full Lug Type Check Valve - CF8.CF8M Solid Lug type dual check valve, CF8.CF8M Wafer Full Lug Check Valve | Made in Taiwan Dual Plate Check Valves Manufacturer | Taiwan Valve Centre Co., Ltd.
It is named the Lug type check valve is because the shape is like the ear. 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.
Full Lug design dual plate check valves are more popular than swing check valves because they have a low slamming effect.
The advantages of a dual plate full lug type check valve compared to a swing check valve are not limited to space saving and lower slamming rate. The total cost of a dual plate full lug type check valve including the sum of initial cost, maintenance cost, and energy cost, is less than a swing check valve.
Full Lug design dual plate check valves are automatic valves that open with forward flow and close against reverse flow.

- Do not have install problem of pipe flange, expecially for small size soild lug check valve.
- Retail acceptable.
- Beautifully packaged.
- Customized special valve.
Dual Plate Check Valve Installation Guide:
When installing a check valve, it can be used in both indoor and outdoor environments. However, if the medium is corrosive or the surroundings are prone to rust, it is essential to select a valve material combination that matches the conditions to ensure durability and safety. For special operating conditions, it is recommended to consult TVCCL’s technical team for professional advice.
Before installation, all debris, oxidation scale, and solid impurities inside the pipeline should be thoroughly removed to prevent interference with the valve’s operation. During installation, the flow direction of the medium must align with the arrow marked on the valve body. The piping should be aligned at the front and rear centers, with flange interfaces kept parallel and bolts evenly tightened. Special attention should be paid to the distance between the check valve and the pump, which should be six to eight times the valve size to ensure stable system performance.
For routine maintenance, regular inspections should be conducted to check for leakage, abnormal noise, or vibration. In addition, the valve should be periodically examined for signs of corrosion, jamming, or other irregularities. Necessary cleaning, dust removal, and residue treatment should be performed to maintain proper equipment operation and extend its service life.

PRESSURE - TEMPERATURE RATING
The pressure-temperature rating table is an essential technical reference in the design and selection of industrial valves. It indicates the maximum allowable working pressure that a valve made from a specific material can withstand at various temperatures. According to the ASME B16.34 standard, this table is based on the mechanical properties and allowable stress of materials, listing pressure limits for different pressure classes (such as Class 150, 300, 600, etc.) at designated temperatures. These values are calculated by considering the reduction in material strength at elevated temperatures, ensuring that valves do not fail due to overpressure or overheating under actual operating conditions. When selecting a valve, users must first determine the operating temperature and then consult the table to verify whether the corresponding pressure class can safely handle the system pressure. The table also categorizes materials into groups—such as carbon steel, stainless steel, and alloy steel—since each material behaves differently under high temperatures, and the allowable pressures vary accordingly. In summary, the pressure-temperature rating table is a fundamental tool for ensuring valve safety. For engineers, it serves not only as a design reference but also as a critical component of risk management.
