Description
The Automatic Air Release valve discharges accumulated air from the system while it is under pressure.
The presence of air in water systems can reduce the effective cross sectional flow area resulting in increased pressure loss and deceased flow.
Unwanted air may also cause water hammer and metering inaccuracies, while hastening corrosion.
In spite of its compact and light weight structure, the S-050 Air Release valve has a 0.014 sq.in orifice that enables it to discharge air at high flow rates and is not exposed to obstruction by debris.

Main Features
• Working pressure range:
S-050: 3 - 250 psi. Testing pressure: 360 psi.
S-050-C: 3 - 250 psi. Testing pressure: 360 psi.
S-052: 3 - 360 psi. Testing pressure: 580 psi.
• Working Temperature: 140° f.
• Maximum working temperature for short time period: 194° f.
• The larger than usual orifice enables it to discharge air at higher flow rates than other Automatic Air Release valves of its kind.
• The enlarged orifice is not exposed to obstruction by debris.
• The valve's design Rolling Seal Mechanism, is less sensitive to pressure differentials than a direct float seal. It accomplishes a comparably large orifice for a wide pressure range (up to 250/360 psi).
• Light weight, simple and reliable structure.
• The body is made of high strength composite materials and all operating parts are made of specially selected corrosion resistant materials.
• A disharge outlet enables removal of excess fluids.s.

Valve Selection
• Available in male threaded sizes: 1/2", 3/4", 1" - NPT
• Available with base made of nylon or stainless steel.
• S-050 V -with vacuum check valve. The valve is available as a valve that will only release air from the system and will not admit air to the system when negative pressure conditions occur. This characteristic is obtained by adding a check valve to the air outlet.

Ordering:
Upon ordering, please specify: model, size, working pressure, threads/flanges standard and type of liquid.
