Latest Patents

One of Lafler's latest patents is a pneumatic volume booster for valve positioners. This system controls the position of a pneumatically operated valve using an electrical control signal from a controller. The pilot circuit of the system incorporates multiple piezo valves that respond to electrical signals from the controller, providing pneumatic output signals to a volume booster circuit. The design utilizes relatively small volume pneumatic pilot signals from the piezo valves to determine the opened or closed state of higher volume valve assemblies. These assemblies connect or disconnect the actuator of the valve to be operated with a source of pressurized gas. Notably, both the piezo valves and the booster valve assemblies are subjected to gas at the same operating pressure. However, the surface area of pistons in the booster valve assemblies exposed to the piezo valves is substantially larger than that of the pistons exposed to operating pressure. This design allows the pneumatic signals to shift the pistons even when the pressure is equal on both sides. The patent also discloses both single-acting and double-acting embodiments, along with alternative versions of booster valve assemblies, including those with a primary piston and a secondary piston. The secondary piston permits partial flow while the primary piston allows full flow when actuated.
