ARV-1-A Air Release Valve 25mm
This 25mm valve is often installed on the top of the filter manifold pipework and at each field valve. It will release air even when the system is under pressure. Don't forget to install a ball valve under the air release valve so that you can clean the valve even when the system is pressurised.
ARV-2-KA Air Release Valve 50mm
This is the 50mm version of the automatic air release valve that is usually installed on field valves over 80mm, at each high point along the main pipe line and, on the primary filter system and all media/sand filters. It is fully automatic and allows air to escape when the system is under pressure and, acts as an anti-vacuum valve or vacuum breaker on system shutdown. This is critical as it protects the system pipework against damage due to excessive vacuum pressures. Don't forget to install a ball valve under the air release valve so that you can clean the valve even when the system is pressurised.
25mm ARI Automatic Air Release Valve
This ARI 25mm automatic air release valve is often used on filters, valves manifolds and main lines to release air under pressure and, allow air into the pipework on shutdown. Don't forget to install a 1" ball valve underneath to allow cleaning while under pressure. Suitable for use on systems to 1,600 kPa and the valve has a sealing pressure of 20 kPa.
50mm Barak Automatic Air Release Valve
This ARI "Barak" 50mm automatic air release valve is often used on filters, valves manifolds and main lines to release air under pressure and, allow air into the pipework on shutdown. Don't forget to install a 2" ball valve underneath to allow cleaning while under pressure. Suitable for use on systems to 1,600 kPa and the valve has a sealing pressure of 20 kPa.
