Full Lined Dual Plate Check Valve(TH-CKV-DPS)

The Full Lined Dual Plate Check Valve is a high-performance, corrosion-resistant industrial check valve specifically engineered to prevent medium backflow in harsh, corrosive, and high-purity pipeline systems. Integrating advanced dual-plate structural design, full lining anti-corrosion technology, and precision manufacturing processes, this valve offers reliable backflow prevention, excellent sealing performance, low flow resistance, and long service life. Unlike conventional check valves, it adopts a full lining design that completely isolates the metal Valve and internal components from the conveying medium, effectively solving the problems of corrosion, contamination, and wear caused by aggressive media, making it an ideal choice for industries requiring strict medium compatibility, operational safety, and stable performance.

1. Two valve plates are fixed on the Valve along a pivot
2. The two springs are installed on the butterfly plate above the sealing surface.
3. Pushed by the medium flow pressure, the spring is compressed, forcing the butterfly plate to open.
4. When the medium flows backwards, the spring forces the valve to close.
5. Good sealing performance
6. Small size and light weight
7. Wide range of applications
8. Valve plate closes quickly
9. Small closing impact
10. Both horizontal and vertical pipelines can be used, easy to install
11. Smooth flow channel, fluid resistance is small
12. Sensitive action and good sealing performance
13. The overall structureis simple and compact, beautiful appearance
14. Long service lifetimeand high reliability

Q1: What is the operating temperature range for this check Valve?
A: The temperature limit depends primarily on the seat material selected. Standard NBR seats operate reliably from -10°C to 80°C (14°F to 176°F), while EPDM seats can handle a broader range from -20°C to 120°C (-4°F to 248°F). For higher temperatures, metal-seated or specialized options would be required.

Q2: Can this valve be used for flow regulation or throttling?
A: No. Check valves Body are unidirectional safety devices designed strictly to prevent medium backflow and protect downstream equipment (like pumps). They cannot be used to regulate or throttle flow rates.

Q3: How is the valve operated, and does it need an actuator?
A: This dual plate wafer check Valve operates entirely automatically and does not require any manual operator or automation actuator. The dual plates are pushed open by the forward flow pressure of the medium and instantly snapped closed by the internal springs when the flow stops or reverses.
