Air And Vacuum Release Valves

Air & vacuum release valves are designed for venting trapped air which collects at high points in the pipeline in manufacturing and production facilities. Raptor Supplies offers various air release valves from brands like Val-Matic, Plast-O-Matic and Marine Industries. These air release valves continuously release the accumulated air from the system, thereby preventing the formation of any large air pockets that can damage the pipelines. These air release valves feature a stainless steel float / poppet that opens / closes as pressure changes. PVC air release valves feature poppet style mechanism for venting out the accumulated air inside the pipeline. PVC air release valves are suitable for applications dealing with low pressures in piping systems. These air release valves are easy to install onto the pipeline ends, usually at a high point for releasing the air. Selected models feature 316 stainless steel construction for withstanding high pressures up to 300 psi while ensuring high resistance against fluids and reactive chemicals. These air release valves have a rubber orifice button constructed of ethylene propylene diene monomer for promoting watertight shutoff during venting. These air release valves are available in 150, 175 & 300 psi pressure ratings on Raptor Supplies, a trusted air release valve supplier of Val-Matic, Plast-O-Matic and Marine Industries.

Air & vacuum release valves automatically exhaust the small amounts of air that usually collects at high points in closed loop pipelines. These SS & PVC air release valves are ideal for water purification, chemical processing, marine and wastewater management industries.

Air release valves are connected to pipelines at the highest point where air collects. Air bubbles that are trapped inside the pipeline enter the valve while displacing the liquid inside the valve, essentially lowering the liquid level. When the liquid level drops to the point where it no longer buoys the float, the valve float drops. The seat pulls away from the orifice by this motion, thereby opening the air release valve and releasing the accumulated air into the atmosphere. As the air is released / vented, the water / liquid re-enters the air release valve and once again buoys the float, thus lifting it to the point where the seat presses against the orifice, thereby closing the valve. This cycle of air release valves automatically repeats to maintain the air free system.

Vestil Air Release Valves:

• Vestil air release valves feature resilient seating for providing positive shutoff during operation, thereby ensuring maximum safety & pipeline system protection.
• These air release valves have 316 stainless steel floats & internal trim for minimising wear against highly abrasive conditions.
• Vestil air release valves feature extended enclosures with a sloped bottom for preventing abrasive materials from reaching the operating mechanism.
• These air release valves have rugged floats for accelerating the valve closure, thereby reducing leakage and chances of valve clogging.

Plast-O-Matic air release valves:

• Plast-O-Matic air release valves feature rugged design for allowing safe expulsion of accumulated unwanted air in piping systems.
• These air release valves have a self guided poppet for assuring the emission of system liquid is minimal before sealing.
• Their true union simplifies the process of valve removal or inspection while ensuring minimum piping breakdown.
• These air release valves require minimal closing pressure (0 psi). The valve closes as the liquid rises after pushing out the unwanted air.
• Plast-O-Matic air release valves feature EPDM seals for sealing the valve shut at system pressure
• These air release valves have poppet style seals. These seals are durable and do not deform under high pressure, unlike hollow ball style seals.
• Plast-O-Matic air release valves have no metal components for protecting the system purity while protecting the valve against harsh chemicals.

• These air release valves are AWWA C512 rated and are NSF 61 & 372 Certified. These valves also meet AWWA C514 standards.
