Our modular design features interchangeable modules held stationary between the valve seat and carrier. There are 12 standard modules in 3 materials, each with varying reed lift and stiffness, so StraightFloTM Valves can cover all speeds and operating conditions of existing industrial compressors and be optimized for any given application.
We use our proprietary Dynamic Valve Sizing Program to determine the optimum module for your situation. This program simulates the valves in the cylinder for the given application, using NIST real gas properties to calculate the reed displacement, velocity, and forces as a function of crank angle to determine the various compressor parameters including flow and power. It takes into consideration the cylinder and frame geometry, the gas composition, and the operating conditions to determine exactly when the reeds open, the flow of gas through the valves and the pressure drop across the valves as a result of this flow. How cool is that?
Each StraightFloTM module is an enhanced reed valve, designed with a straight-through flow path. Since the gas doesn't have to traverse the usual tortuous, high-loss path, our valves have the highest effective area for a given diameter.
What's more, the module's plastic components don't move or impact the metal housings. So not only is wear-and-tear completely contained inside the modules, but compressors with StraightFloTM Valves typically operate at 1/10th the vibration levels of those with conventional valves.
Since the reeds act as both the sealing element, and the spring element the lowest natural frequency of our modules is 250Hz, well above any excitation force from an engine or motor. This high separation from excitation forces practically eliminates failure due to resonances. It also makes our valves suited to much higher speeds than are currently common in the field. Compare this to a maximum of 30Hz for poppet valves and about 80Hz for plate/ring valves where a mass (poppet/plate/ring) has helical coil springs supporting it.
The straight-through flow path makes our valves self-cleaning and highly tolerant to liquids and solids. When the reeds are wide open, liquids and solids go right through the module without any impact on the critical sealing faces. With conventional valves, liquids and solids strike hot, highly stressed plastic, often causing embedded particles, breakage, and affecting the sealing surface to the point where the valve must be serviced. With StraightFloTM Valves, that doesn't happen.
Its modular design means the StraightFloTM Valve can be easily serviced in minutes. Just unscrew the valve seat, slide out the old modules with your fingers, slide in the new, and reattach the valve seat to the carrier. There’s no need to ship valves offsite for machining. Plus, inventory can be minimized by over 80% compared to conventional valves. Stock 6 to 8 module types and your entire fleet of compressors is covered—no matter the brand, cylinder size, application or operating condition—so you can repair any valve in the field, without having to return to a warehouse to get the right valve or parts.
No machining means the valve seat pressure rating never
drops below that of the new valve.
It also eliminates the chance of machining errors that result in tolerance stack up and prevent valves from being installed during service.
StraightFloTM modules are truly interchangeable between valves, whether they’re 1.5" in diameter or greater than 14", whether they’re suction or discharge valves; whether the valve goes into a cylinder made by Manufacturer X or Manufacturer Y.
They’re also easy to re-rate for a new application—just change out the present modules with modules rated for the new application. As long as the valve seat is pressure-rated for the new application, you now have a valve for a brand new application at very little cost.
The StraightFloTM Valve guarantee is 2x the MTBF (mean time between shut down of compressor due to valve issues) of the compressor compared to MTBF with the valves we replace under the same operating conditions (includes quality of gas) plus 10% reduction in valve losses.
