The SV291 and SV292 valves
are 2-way, pilot operated, antiwaterhammer, and normally open.
These valves are designed
to reduce or control waterhammer,
which typically occurs with
incompressible fluids when the
closing of a valve creates a sudden
change of the fluid velocity.
Restriction of the pilot flow in these
valves will prevent them from
slamming closed. Valve and piping
system life is enhanced since
the noise, vibration, and shock of
waterhammer are reduced.
Where small flows (CV <3.0) at
relatively low pressure differentials
are present, the waterhammer is
eliminated by the fixed restriction of
the pilot flow. This is the standard
design for the industry. However,
to reduce waterhammer in highflow applications, a unique field
adjustment device can effectively
control the waterhammer in an
application. The closing time on
these valves can be adjusted by
a 4-position selector. Position 1
allows the fastest closing,
position 4 the slowest.
