BLA series fork type pneumatic actuator

BLA series fork type pneumatic actuator

Brief description: BLA series toggle-type pneumatic actuator has large opening and 

closing torque and is 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,

 toggle-type pneumatic actuators When the valve is operating, the output 

torque can change as the angle changes, and the maximum torque value 

can be provided at the valve's open or closed position, which exactly matches 

the required torque of the valve, making the valve open and close more smoothly.

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:
