MODEL KDV SERIES “FREEZELESS” DUMP VALVE
INSTALLATION AND OPERATING INSTRUCTIONS
The Kenco KDV series Dump Valve is a pneumatically controlled valve designed for fluid level control
in gas scrubbers, separators and other process pressure vessels. It is available with either 1” or 2”
process connections. The drain sizes available are ½”, ¾” and 1” depending on the model used. The
valve actuation pressure range is 30-70 psi depending on the model and process pressure (see figure 2).
Process pressure ratings of up to 2000 psi are available.
• Features:
•Ease of Maintenance-The union nut allows the
valve to be removed for service without removing
the Valve Body from the pressure vessel.
•Variety of Trim Sizes- Several trim sizes
available to accommodate different flow and
pressure requirements.
•High Performance Polyurethane Trim Seal-The
high performance polyurethane material used on the
Trim Seal is more durable and longer lasting than the
urethane used on competitive valves.
• Pressure Warning Port-If an attempt is made
to remove the valve assembly from the body
while the valve is under pressure, process fluid
and/or gas will leak from the weep hole to provide
a warning.
• “Keyed” Housing to Valve Joint-Valve is
keyed to diaphragm housing to ensure internal
retaining hardware does not twist or vibrate loose.
•Simple Installation-Valve is easily installed
with simple hand tools in a short amount of time.
