WARNING!

Personnel involved in the installation or maintenance of valves should be constantly alert to potential
emissions of pipeline material and take appropriate safety precautions. Always wear suitable protection
when dealing with hazardous pipeline materials. Handle valves, which have been removed from service
with suitable protection for any potential pipeline material in the valve.

SECT: 1.03 SAFETY MESSAGES

All safety messages in the instructions are flagged with an exclamation symbol and the word

“Caution,” “Warning,” or “Danger.” These messages indicate procedures that must be followed

exactly to avoid equipment damage, personal injury or death. Safety label(s) on the product
indicate hazards that can cause equipment damage, personal injury or death.

If a safety label becomes difficult to see or read, or if a label has been removed, please contact
International Valve Marketing for replacement labels(s).

SECT: 1.04 RECEIVING, INSPECTION AND STORAGE

Your Vent-Tech Model SWG, Series C, B, V and N waste water air release and vacuum relief valve
has been packaged to provide protection during shipment; however, it can be damaged in
transport. Upon receipt, inspect the unit for damage and file a claim with the carrier if damage
is apparent. Carefully, unload all valves to the ground without dropping. The valve should be
lifted by the body, the sealing flange fasteners or where applicable, the factory supplied lifting
lugs included with your shipment.

If installation will be delayed, the valves should remain in a clean, dry and weather protected
area until installed. All threaded connections should be protected from damage.

SECT: 1.05 DESCRIPTION

The Vent-Tech Air Relief Valves work in many different types of environments, protecting
pipeline infrastructure against the effects of water hammering and vacuum. High quality
stainless steel parts, HDPE floats, anti-wear inserts and air flow design enhancements are
components of each Vent-Tech sewage air relief valve. When combined with Vent-Tech’s
superior design elements, these materials ensure that the valve operates in highly corrosive
environments within a wide range of pressures and temperatures. Each valve body contains air
flow enhancements to maximize flow under vacuum conditions.

All Vent-Tech Model SWG Sewage valves consist of 4 primary assemblies. These are:

(a) Inlet Connection

There are 4 series of valve configurations available in the Model SWG line of Vent-Tech Sewage
valves. Inlet configurations can be adapted to many configurations to pipe discharge effluent
gasses for treatment using elbows, vertical tees, horizontal tees and/or swivel flanges. Your
particular configuration may not match exactly the following depictions.

The functions of a model SWG Sewage valve are:

(i) Series C:

 Allow large air release at start-up
 Discharge of air/gas from pressurized pipeline
 Surge control to prevent the development of hydraulic transients during start-up and

pressure surges

 Full port, high volume air intake for vacuum relief

(ii) Series B:

 Controlled air/gas discharge at pump start up
 Discharge of air/gas from pressurized pipeline
 Surge control to prevent the development of hydraulic transients during start-up and

pressure surges

 Full port, high volume air intake for vacuum relief

(iii) Series V:

 Allow large air release at start-up
 Discharge of air/gas from pressurized pipeline
 Surge control to prevent the development of hydraulic transients during start-up and

pressure surges

(iv) Series N:

 Full port, high volume air intake for vacuum relief

(b) Valve Body

(c) Base Flange
