The SW series is retainerless. The SLP is non retainerless through pinned, design and lends itself to the
applications requiring limit/micro switches, counter weights, etc. The SLP and SW flapper has spring
assisted closing, suitable for horizontal or upwards vertical service (downwards required an external
closing spring, which is an available option in SLP series). A large bore provides a larger flow when
compared to dual flap style or slim line uniflap checks.
SLP SERIES (retainer type)
Light and strong
Supercheck SLP/SW series valves are light, so line stress is reduced to a minimum. Yet the installed valve
assembly is more rigid than an equivalent length of heavy-walled pipe.
Smooth, fully automatic operation
The SLP/SW series valves are designed to be fully automatic in function. The smooth opening and closing
action reduces line hammer to a minimum. SLP/SW series valves are engineered to present an essentially
unobstructed orifice.
SLP SERIES (Retainer type)
SW SERIES (Retainerless)
Simplified design
The SLP/SW series are made with a minimum of parts. The stainless steel trim and resilient O-ring seat
(soft seated version) ensures long life. The single O-ring ensures a complete leak-free seal.
