Product name：Swing check valve with sealed welded cover and threaded sleeve
Product introduction：
Swing check valves to ANSI/ASME standards with threaded socket (NPT), welding ends (BW) or weld sleeves (SW), Trim 8 (Stellite/13% chrome steel), with cover flange (class 800) or seal weld cover (classes 1500 and 2500), with internal shaft, available in carbon and alloy steel.
Application：
1. Boiler feed water
2. Conventional power plants
3. Petrochemical industry
4. Pipelines and oil storage tanks
5. Refinery equipment
6. Process technology
Advantages：
1. The armored sealing surfaces (seat and disc) are made of wear-resistant and corrosion-resistant materials, which ensure a long service life and high functional reliability.
2. Reliable sealing. The labyrinth cover seal on both sides prevents the sealing gasket from sagging.
3. Reduced leakage risk due to the internal shaft
4. Longer maintenance-free operation due to the additional wear resistance provided by the armored overlay on the disc and seat ring.
