TITLING DISC CHECK VALVE



FUNCTION

Today, higher velocity and pressure of piping often requires a sophisticated check valve rather than conventional swing type valve. PK tilting disc check valve is designed to handle such higher velocities, prevent damages due to turbulence and avoid “water hammer”phenomenon in piping systems, and it is closed quickly and quietly. The valve is closed quickly because its pivot(hinge pins) is shut by a very small arc.Moreover, line fluid flows both over and under the disc, so that valve closing is cushioned by the line fluid itself. By virtue of quick and quiet closing ability, up to now PK tilting disc check valve has earned good reputation as a “non-slam”check valve.

BODY

Body-cover joint of swing-check valve are machined as follows:
Class 150 ................................................. Male and female.
Class 300 and 600 .................................. Male and female.
Class 900 and 1500 ................................. Ring type joint.
We can supply any kind of gasket per customer requirements.

SEAT RING

Seat rings are welded into valve bodies in order to prevent turbulence and avoid damage due to corrosion seats, forged or rolled in one piece for all dimensions, heat treated to obtain the required surface hardness, and perfectly cleaned before assembly.
