HYDRAULIC VALVE KIT
for
SINGLE WATER CIRCUIT
SYSTEM
(
SWC
)
:
Valve kit includes an adjustable FLOW LIMITING VALVE
2.5
for continuous dust suppression, LS Valve with
FLOW LIMITER
2.6
for high power dust suppression (adjusted in factory), two SOLENOID VALVES
2.7
and
2.8
respectively and PRESSURE RELIEF VALVE
2.9
.
By activating the solenoid valve
2.7
, the
continuous dust suppression is being started.
Water flow is rated by setting of flow limiting valve
2.5
, which can be re-adjusted within certain limits.
Hydraulic fluid flow Q1 is directed to the pressure
port of HPW-pump through above components
and fixed flow limiter
2.6
.
The High power dust suppression is switched by activating the solenoid valve
2.8
when system’s operation
(primary hydraulic flow and secondary water flow) is rated tothe fixed flow limiter setting
2.6
. Pressure relief
valve protects the equipment against damages.
