BLA series toggle-type pneumatic actuators have large opening and closing torque and are more suitable for butterfly valve and ball valve control.
One of the motion characteristics of butterfly valves and ball valves is that the starting point and closing point require the largest torque. Similarly,
when the toggle-type pneumatic actuator is operating , the output torque can change as the angle changes, and it can provide the maximum torque value
at the valve's open or closed position, which exactly matches the required torque of the valve, making switching the valve smoother.
Structural features: Small size, light weight, easy to install. Due to its unique fork-type large torque structure, it is lighter than rack-type pneumatic actuators
under the same output torque, and the volume and weight can be reduced. 30% smaller. Faster working speed. Compared with rack-and-pinion pneumatic
actuators of the same torque, the cylinder body is smaller and the switching speed is increased by 40%. It is especially suitable for harsh working conditions
such as high frequency and fast speed. Longer service life. The fork-type actuator converts traditional sliding friction into rolling friction. The aluminum alloy
piston has no direct contact with the steel shaft, which greatly reduces the wear of transmission components; smooth and wear-resistant sleeves, multi-point
The guide seal not only improves the sealing performance, but also plays a supporting and fixing role, making the piston and fork more stable during movement.
The service life can reach more than 1,000,000 times. Technical parameters 1. Flange connection standard: UNI EN ISO 5211: F03-F04-F05-F07-F10-F12-F14-F16-F25:
