Pneumatic

The valve body is precision cast with standard geometric dimensions. The manufacturing process ensures the sealing of the valve and ensures no leakage during opening and closing.
The thickness is more than 8% thicker than similar vacuum pneumatic butterfly valves, which better ensures the pressure-bearing capacity of the electric clamping butterfly valve.
The actuator shell is made of aluminum alloy precision die-casting and has a thickened shell. It is beautiful and elegant, and has excellent durability and corrosion resistance.
The standard indicator makes it easy to install position switches, positioners and other accessories. The double-piston rack is made of galvanized cast steel. The installation position is symmetrical, it operates quickly and has a long service life. Simply invert the piston to change the direction of rotation.
High-performance spring, made of high-quality materials and coated pre-loading device. It has strong corrosion resistance and long service life. Able to safely and easily disassemble single-acting actuators to meet different force rectangular output ranges by changing the number of springs
