Unirain 1" Kinetic Air
Release Valve
 ARV-1"K
This air release valve performs two
functions:
- Exhausts trapped
air in pipes as they fill. When water reaches the inside of
the valve, the float rises and closes the outlet.
- Prevents pipe
collapse.
If depressurisation happens the float drops, opening the
outlet and allowing air to enter the pipes, destroying the
vacuum and returning atmospheric pressure to the inside of
the pipe.
Features
- Valve is totally sealed
even at very low pressure
- Simple in design with only
five parts, it is easy to disassemble when cleaning is
required.
- Elbow outlet with integral
internal filter prevents foreign objects entering the valve.
Technical Specification
- At least 501 m³/hr of air
is released when fully open
- Released air volume is at
least 0.026 m³/hr at 0.35 Bar
- Totally sealed from 0.21
Bar
- Working pressure of at
least 15.5 Bar
- Fibre-glass reinforced
polyamide construction
- Treated for protection of
UV radiation
- 1" Male BSP base thread
- ¾" Horizontal threaded
cutlet with filter
- Full technical data and
information available on request

Unirain 2"
Kinetic and Automatic Air Release Valve
 ARV-2"KA
This air release valve performs three
functions:
- Exhausts trapped
air in pipes as they fill. When water reaches the inside of
the valve, the float rises and shuts the outlet.
- Exerts continuous
automatic venting control eliminating any residual
pockets of air that might reach the valve
- Prevents pipe
collapse.
If depressurisation happens the float drops, opening the
outlet and allowing air to enter the pipes, destroying the
vacuum and returning atmospheric pressure to the inside of
the pipe.
Features
- Unique double seal system,
one for kinetic performance the other for automatic
control. The low density float makes the valve completely
watertight as the pipe is being pressurised or emptied, no
matter how slowly these operations are carried out.
- Elbow outlet with integral
internal filter prevents foreign objects entering the valve.
Technical Specification
- At least 1002 m³/hr of air
is released when fully open
- Totally sealed from 0.21
Bar
- Working pressure of at
least 15.5 Bar
- Fibre-glass reinforced
polyamide construction
- Treated for protection of
UV radiation
- 2" Male BSP base thread
- 1¼" Horizontal threaded
outlet with filter
- Full technical data and
information available on request.
