Vent-O-Mat RBX: Revolutionizing the World of Air Valves

In the world of fluid control, the efficient and reliable operation of pipelines is crucial. Whether it’s sewage and wastewater systems, mining applications, or other industrial processes, the use of air valves plays a vital role in maintaining optimal performance. One company that stands out in this field is Vent-O-Mat, with their innovative RBX air valve technology. Vent-O-Mat has incorporated tested and patented features into their RBX air valves, making them a game-changer in the industry. In this article, we will explore the unique features and benefits of Vent-O-Mat RBX air valves and why they are revolutionizing the world of air valves.

Compact Design for Enhanced Efficiency

One of the standout features of Vent-O-Mat RBX air valves is their compact design. Unlike conventional designs, which require separate double-acting air valves and surge alleviation devices, Vent-O-Mat RBX combines both functions into a single chamber body construction. This not only reduces the size of the valve by up to a third but also eliminates external auxiliaries that can be tampered with or accidentally removed. The tamper-proof nature of Vent-O-Mat RBX makes it ideal for applications in both first and third-world conditions, ensuring reliable and efficient operation.

Full Flow Areas for Optimal Performance

Efficient air intake and discharge are essential for the proper functioning of air valves. Vent-O-Mat RBX air valves are designed with full flow areas, where the discharge and intake areas equal the nominal size of the valve. This design allows for the least resistance to air intake and discharge, resulting in a more efficient performance compared to conventional designs with reduced outlets. The larger orifice sizes in Vent-O-Mat RBX air valves ensure optimal airflow capacity, contributing to improved system efficiency.

Integral Surge Alleviating Device for Enhanced Protection

Surge pressures can pose a significant risk to pipeline systems, especially during initial filling and pump trip conditions. Vent-O-Mat RBX air valves are equipped with an integral surge-alleviating device as a standard feature. This device automatically dampens surge pressures, protecting both the valve and the pipeline from potential damage. This technology, pioneered by Vent-O-Mat, offers superior surge protection compared to other manufacturers who have attempted to replicate it. The effectiveness of Vent-O-Mat RBX air valves in surge protection is well-documented and can be comprehensively modeled in surge analysis software packages.

Solid Floats for Unmatched Durability

The floats used in Vent-O-Mat RBX air valves are made of solid high-density polyethylene, ensuring durability and longevity. Unlike other designs that use hollow floats prone to implosion or distortion, the solid floats in Vent-O-Mat RBX air valves offer superior strength and resilience. This design choice enhances the overall reliability and performance of the valve, even under challenging operating conditions.

Cylindrical Floats for Optimal Closure

In vacuum conditions, some air valves may experience partial closure, leading to inefficiencies and potential issues with system performance. Vent-O-Mat RBX air valves address this challenge by incorporating cylindrical floats. The use of cylindrical floats discourages partial closure under vacuum conditions, ensuring proper sealing and efficient operation of the valve.

Three Discharge Orifices for Effective De-aeration

Efficient de-aeration is crucial in pipeline systems to maintain optimal flow and prevent air pockets or blockages. Vent-O-Mat RBX air valves feature three discharge orifices, providing effective de-aeration under all pipeline flow and operating conditions. This design ensures that air pockets are quickly and efficiently released, maintaining continuous and smooth fluid flow throughout the system.

Low Head Sealing for Leak-Free Performance

Proper sealing is essential to prevent leaks and ensure the integrity of the pipeline system. Vent-O-Mat RBX air valves incorporate a dynamic seal that adjusts to the applied pressure. The flat face of the float makes contact with the seat, effecting a drip-tight seal even at low pressures as low as 2 meters. This meticulous attention to sealing ensures leak-free performance, preventing any loss of fluids or compromising the efficiency of the system.

Versatile Materials of Construction for Diverse Applications

Vent-O-Mat RBX

Vent-O-Mat RBX air valves are available in a variety of materials, including ductile iron and stainless steel (304 or 316). This versatility enables the valves to be used in a wide range of applications and environments, catering to diverse industry needs. Whether it’s sewage and wastewater systems, mining operations, or other industrial processes, Vent-O-Mat RBX air valves can be customized to meet specific requirements, ensuring optimal performance and durability.

Extensive Pressure Ratings and Size Range

Vent-O-Mat RBX air valves are designed to meet various pressure ratings, offering flexibility and adaptability for different systems. As a standard, the valves are manufactured for pressure ratings ranging from PN16 to PN40. For more demanding applications, Vent-O-Mat can provide valves with pressure ratings of PN64 and PN100 upon request. Additionally, Vent-O-Mat manufactures the largest range of air valves, offering sizes from DN25 to DN300. This extensive size range ensures that Vent-O-Mat RBX air valves can be used in a wide range of pipeline systems, catering to the diverse needs of different industries.


Vent-O-Mat RBX air valves represent a significant advancement in air valve technology. With their compact design, full flow areas, integral surge alleviating device, solid floats, cylindrical floats, three discharge orifices, low head sealing, versatile materials of construction, extensive pressure ratings, and size range, Vent-O-Mat RBX air valves offer unparalleled efficiency, reliability, and performance. These innovative valves provide a comprehensive solution for industries such as sewage and wastewater systems, mining operations, and various industrial processes. By choosing Vent-O-Mat RBX air valves, industries can benefit from enhanced system performance, reduced maintenance costs, and improved overall operational efficiency. Vent-O-Mat’s commitment to innovation, quality, and customer satisfaction sets them apart as a leader in the field of air valve technology.
