Applications
Titanium Swing Check Valve are widely used in industries include oil, chemistry, pharmaceutical, fertilizer, and power generation to prevent the backward flux of the media.

Design Feature
Lift type/Swing type/Dual plate
Full bore/Reduce bore
Bolted bonnet
Renewable seat/integral seat
Plug type disc/Flat type disc
The surface form a protective film after Hare face treatment for trim. It not only improves anti-corrosion performance, but also can open close easily because of improved surface hardness.

Technical Feature
1. Eyebolt hook design upon size≥4”, easy for on-site installation.
2. Fully capped spiral wound gasket inserted in valve groove as per figure 1.
3. Keep tight, long last and reliable sealing performance.
4. The design of the body/cover gasket varies depending on the class of the valve. Class 150 to 600 check valves consist of a bolted connection with a graphite or spiral wound gasket. Class 900 and above check valves consist of a ring type joint. In pressure seal designs the sealing is achieved through a gasket that takes advantage of the internal pressure of the line. The material most commonly used is high purity graphite being located between the body and the body retainer ring.
5. Bolted bonnet connection for easy access to internals.
6. No Retainer design for pin and disc connection as per figure 2, ensure the sealing performance.
7. Integral Metal Seat applicable for high temp application, and easy for disc maintenance.
8. Body waist drum structure with good streamline and large CV values and strong circulation.
