Note: CoCr alloy as used throughout this catalog refers to cobalt chrome hardfacing alloys as supplied by Kennametal Stellite™ and other approved manufacturers.

API standard 594 trimAPI 594 Eight Edition, September 2017; Clause 6.4.1, defines “trim” as: l body seating surface l plate or disc seating surfaces

Design featuresl Body surface with uninterrupted gasket surface . l The reduced weight of the disc is a major factor in minimizing

slamming and water hammer.l The side hinges on the discs, eliminate the effect of gravity

resulting in lower energy costs. l Design maximizes the flow path area through the valve with a

lower pressure drop. The internal retention method does not encroach on the gasket sealing surface

l Retainerless body with no holes through the body wall, so leakage to the outside is impossible, therefore emissions-free.

l Intrinsically fire safe with no drilling through the body wall.l Quick acting springs provide a fast-acting response to flow reversal,

while designed to minimize stress and maximize service life.l Velan dual plate check valves easily meet and exceed test

requirements of API 598 for metal-seated check valves.l Shock bumper arrangement on the back of each disc reduces the

shock force on the hinges; ensuring internal components have an extended cycle life with minimal wear under the most severe service conditions.

l Extended seat life due to the clearance between the disc hinge and hinge pin which eliminates any dragging effect.
