Swash Plate Type Check Valve

Structural features:

SENSI Swash plate type non-impact check valve is a non-impact check valve with a flange size of ASME B16.5 GB HG SH. The main advantage is to overcome the impact of the swing-type check valve and the lift-type upper return valve under working conditions, and to achieve a non-impact operation.

1. Double eccentric valve flap, when closed, the valve and the sealing surface are gradually contacted to achieve no impact and no noise.

2. Micro-elastic metal seat with good sealing performance.

3. The butterfly valve design makes the switch quick and sensitive and has a long service life.

4. The swash plate structure makes the fluid passages streamlined, with small flow resistance and energy saving effect.

Performance characteristics

Performance	Swing check valve	Swash plate type check valve
Closing force	Large	Small (about 1/5~1/8 of the former)
Impact force	Large	No
Sealing	Allow leakage by API 598	Zero leakage
Flow resistance	Large (flow resistance coefficient ξ = 1.3~2.5)	Small (flow resistance coefficient ξ = 0.18 ~ 0.6)
Circulation capacity	Small (flow coefficient Cv=76)	Large (flow coefficient Cv=154~333)
weight	Larger	Smaller (about 80% of the former)
