Control valves
Two types of valve body has been qualified for controlling the water flow in ARIA units cooling or heating
coils.
2 way valve body and 3 ways with bypass:
- brass valve
- stainless steel stem
- flat face for washer seal
- bronze body
- male thread 1/2G
- fluid: water with max 50 % glycol.
- leak rate < 0.20% of kvs
- flow coefficient (kvs) : see table
- differential pressure : see table
In addition, 2 types valve actuator has been selected, to control the opening and closing of the above valves.
Proportional valve actuator
These actuators have been designed to operate with
V5832A and V5833C valve bodies; this allows proportional
operation by 3 point control.
Characteristics :
- Power supply :
