Pneumatic butterfly valves

Pneumatic butterfly valves

To deal with highly inflammable liquids such as oil, gas and petrochemicals, ideal for use case is pneumatic butterfly valve. To allow fast functionality and prevent fire problems and electric short circuits, it is operated by pneumatic. So, with the cost factor being the lowest, it is the only electricity efficient operated valve. These butterfly valves are often demanded on a large scale by industries such as coal, paper, chemical, petroleum, etc. Pneumatic control butterfly valve is used in low pressure standards. Adding to this, it inherits more economical values because of its larger diameter and larger the diameter, more economical it exhibits when used. They also reduce the maintenance design because of their simplistic structure, which also enhances work efficiency.

It Is very important that we understand that how a pneumatic operated butterfly valve operates and how it exhibits unique characteristics.

  • It uses the power source in the form of compressed air and the valve stem are driven to control the disc-shaped butterfly plates while rotating around the axis.
  • According to the required actual needs and expectations, initial position of the valve is determined.
  • When you rotate the valve by an angle of 90-degree, one action is ended. It may be a situation such as by opening to off or from off to on. It also results in another action getting ended (either from off to on, or on to off).

These are the ideal three working principle which makes this sanitary pneumatic butterfly valve relatively faster. They also do not require manual working where people have to manually close or open the valves. Based on actuators, they are divided into single-acting and double-acting. Among these two, single-acting actuator have the ability to return spring, which is supported by automatic opening and closing of the case.
