With headquarters in the USA, ROSS also has offices in Germany, France, China, India, Japan, Brazil and the United Kingdom, to deliver local technical expertise for your global needs. Our goal is assist smelter customers to surpass their productivity goals and exceed their sustainability goals using proven and reliable air solutions.
ROSS Poppet valves are the valve technology of choice for the Smelter Industry. With proven long-life, reliability and unsurpassed performance, the ROSS Poppet has proven itself over many decades in the challenging and unforgiving smelter environment. Overwhelming shifting force in each direction is the key to the ROSS Poppet. Being a true poppet, its perpendicular face seal design delivers self-cleaning and self-compensating sealing to minimize leakage (~ zero) compared to any other internal valve construction on the market. Alumina dust and other pipe debris is no match for the ROSS Poppet.
ROSS poppet valves have positive sealing with no sliding action to prevent damage and wear. They are also self-cleaning and dirt tolerant thanks to the smallest flow-through area across the poppet’s seal and seat which produces a high-enough velocity to blow out all dirt and foreign matter. Plus, the valve is self-compensating for wear by automatically changing stroke length due to height changes in the valve seal from burnishing. These valves are designed for repeatability, high-temperature service, high speed, and high-shift consistency over the life of the valve.Browse Our Catalog
27 Series poppet valves for inline mounting are available with single or double solenoid pilot control and pressure control. The poppet construction offers near zero leakage and high dirt tolerance. The valve design provides self-cleaning and is wear compensating. All of these features provide these valves with high repeatability throughout its life.
Special control functions can be added with adaptors that are placed between the valve body and the pilot. These functions include timed delays, increasing the piston’s actuating force, and converting a single control valve into an impulse controlled, detent valve. 21 Series valves are configured like the 27 Series valves, but are designed with metal internals and special seals appropriate for use in more extreme temperatures.
