A.R.I. S015 EN - Manual

Installation and Maintenance of
S-015 Automatic Air Release Valve
A. Installation
A.1 The air valve will be mounted on a riser,
connected to the top of the pipe.
A.2 A shut-off valve will be installed below the air
valve.
B. Operation
The S-015 Automatic Air Release Valve releases entrapped air from
peaks and along pressurized systems where the valve should be installed.
Pockets of accumulated air may cause the following destructive phenomena:
* Impediment of effective flow and hydraulic conductivity of the system, along with a throttling
effect
as would a partially closed valve. In extreme cases this will cause complete flow stoppage.
* Accelerate cavitation damages.
* High pressure surges.
* Accelerate corrosion of metal parts.
* Danger of a high-energy burst of compressed air.
* Inaccuracies in flow metering.
C. Basic Periodic Maintenance
C.1 Close the shut-off valve below the air valve.
C.2 Unscrew the Cover Bolts (8-10) of the automatic air release valve slowly,to release
accumulated pressure .
C.3 Remove the Cover (2) of the automatic a.r.v., clean the Orifice (5) with flowing
water or a burst of pressurized air.
C.4 Wash the inside of the Body (1), the Float (3), and the Rolling Seal (7)
with clean water.
C.5 Check to make sure the Rolling Seal is unharmed (not torn or cracked) .
If it needs to be replaced, see below, Instructions for Replacing the Rolling Seal .
C.6 Reinstall in reverse order and fasten and tighten all bolts. Make sure to re-assemble
all the components correctly.
C.7 Open the shutoff valve beneath the air valve.
