Quick Detail
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.
