Tilting Disk Check Valve

Tilting disk check valve is a check valve based on the double eccentric disc design. It can achieve rapid opening and closing by tilting and rotating the disc, avoiding the impact and water hammer effect of traditional check valves. It is suitable for working conditions with strict requirements for low flow resistance, high sealing and rapid response.

‌Core features‌:

‌Non-impact closing‌: The disc gradually contacts the sealing surface of the valve seat to eliminate mechanical collision and noise during opening and closing; ‌Streamlined flow channel‌: Venturi-type channel design, low flow resistance coefficient (about 40% lower than traditional check valves), significant energy saving effect; ‌Multi-material adaptation‌: The valve body can be selected from stainless steel, Hastelloy, etc., suitable for high temperature and corrosive media (such as steam, chemicals). Core structure and design specifications
‌Key components‌

‌Valve body and disc‌:
The valve body adopts an integral casting process (some patented designs integrate the air pump pressure-maintaining shell to improve sealing reliability);
The disc is a double-eccentric butterfly structure, and the tilt angle design (such as 60° sealing line plane angle) realizes pendulum motion.
‌Sealing system‌:
Metal hard seal (tungsten carbide spraying) or elastic soft seal (polytetrafluoroethylene liner), supporting zero leakage standard;
Some models are superimposed with slow return springs and buffer screws to reduce closing impact force.
Design specifications‌

‌Standards‌: ASME B16.34 (design), ASME B16.10 (structural length), API 598 (test);
Pressure level‌: Class 150~2500 / PN2.0~42.0MPa;
Diameter range‌: DN15~DN3200.

 

Tilting Disk Check Valve

 

Advantages and selection points
‌Advantage comparison‌
‌Opening and closing speed‌: The closing time of the spring-assisted model is ≤0.5 seconds, which is 2 times faster than the swing check valve; ‌Installation flexibility‌: Supports horizontal, vertical and any angle installation (no additional support required).
‌

Selection points‌
‌Media characteristics‌: Clean liquid/gas is preferred to metal seal; particle-containing media requires a pre-filter; ‌Pressure matching‌: High-pressure long-distance pipelines (such as Class 600 and above) require customized forged valve bodies; ‌Control requirements‌: Intelligent models with electric/pneumatic actuators can be selected for flow regulation scenarios.
