PXH44H swash plate check valve

Design specification

Flange size according to: ASME B16.5 GB HG SH
Pressure rating: Class 150, 300, 600 PN 2.0, 5.0, 10.0 MPa

Structural features

Double eccentric valve disc, when closed, the valve seat and the sealing surface gradually contact, to achieve no impact, no noise work.
The micro-elastic metal seat has good sealing performance.
Butterfly valve disc design, quick switching, sensitive, long service life.
Swash plate structure streamlines the fluid channel, small flow resistance, energy saving effect.

Performance Characteristics

Performance	Swing check valve	Swash plate non-impact check valve
Closing force	big	Small (is about 1/5 ~ 1/8 of the former)
Impact Force	big	There is no
Tightness	Press API 598 to allow leaks	Zero leaks can be achieved
Flow Resistance	Large (flow resistance coefficient ξ=1.3 ~ 2.5)	Small (rheostatic coefficient ξ=0.18 ~ 0.6)
