Full bore equivalent type stainless steel small pneumatic automatic ball valve
LAS-157 type
Space-saving and disassemblable full-bore equivalent model.
A small pneumatic automatic valve made of stainless steel, equivalent to a large flow and full bore. It has a flange connection, allowing for disassembly and cleaning of internal components such as the ball. Additionally, the aluminum actuator equipped with a rack and pinion mechanism is high-torque, lightweight, and compact, capable of rotating in 90° increments. It is ideal for piping in tight spaces and for installation in devices that require miniaturization. Furthermore, there are numerous achievements in custom-made (specification changes) products based on this model.
