Cla-Val 100-20KO - Manual

100-20 KO
Anti-Cavitation Hytrol Valve
Full Open Operation
When pressure in the cover chamber is
relieved to a zone of lower pressure,
the line pressure at the valve inlet
opens the valve, allowing full flow.
Modulating Action
The valve holds any intermediate posi-
tion when operating pressures are
equal above and below the di-
aphragm. A Cla-Val “Modulating” Pilot
Control will allow the valve
to automatically compen-
sate for line pressure
changes.
Tight Closing Operation
When pressure from the valve inlet
is applied to the cover chamber, the
valve closes drip-tight.

The Cla-Val Model 100-20KO Anti-Cavitation Hytrol Valve is designed for appli-
cations where there is a high potential for damage from cavitation. Specify this
valve series for a wide variety of control valve applications having pressure dif-
ferentials up to 350 psid or for relief valves having atmospheric discharge up to
150 psid.
The 100-20KO Hytrol main valve provides optimum internal pressure control
through a unique anti-cavitation trim design. Constructed of 316 Stainless Steel,
the seat and disc guide trim components feature dual interlocked sleeves con-
taining radial slots that deflect internal flow to impinge upon itself in the center of
the flow path, harmlessly dissipating the potential cavitation damage. This unique
design also lessens the possibility of fouling if large particles in the water are pres-
ent due to the large flow path of the radial slots.
The 100-20KO Hytrol is the basic valve used in Cla-Val Automatic Control Valves
for high differential applications requiring remote control, pressure regulation, so-
lenoid operation, rate of flow control, or liquid level control.
The Anti-Cavitation Trim components can be retrofitted to existing valves if the
application indicates an appropriate need. Please consult factory for details.
