Watts Product Information
Basic Check Valve
Model BSS
The Basic-Check valve is a versatile all-purpose,
spring-assisted, in-line check valve that provides reliable,
low maintenance service for a wide range of liquids and gases
at various pressure/temperature combinations. The valve consists
of a guard cage, spring, valve disc, retaining ring, and seat.
It can be combined with pipe fittings such as reducing couplings,
drain elbows, etc. to form a complete check valve unit ideally
suited for a broad range of pipeline applications or incorporated
into machinery for OEM applications. The metal-to-metal sealing area
of the Basic-Check valve's disc and seat is precision lapped,
providing very tight shut-off of both gas and liquid.
If bubble-tight shut-off is required, resilient soft seats are available.
