Description

Ball valves can be combined with a pneumatic actuator (pneumatic ball valves) for automation and/or for controlling remotely.

 

What is a Pneumatic Ball Valve?

ZECO pneumatic ball valve is composed of pneumatic actuator and ball valve named. The advantage of pneumatic ball valve is the fast switching speed, the normal switching speed can reach 0.05 seconds/time, also because of the fast switching, ZECO pneumatic ball valve is often used as a quick cut-off valve on the pipeline. Pneumatic devices are often equipped with solenoid valve, air source processing triplets, limit switch, positioner and control box, so ZECO pneumatic ball valve and electric ball valve can also achieve remote operation.

 

What is Pneumatic Actuator?

Pneumatic actuators control ball valves by the conversion of compressed air energy to mechanical motion. A rotary mechanical motion is required in a ball valve for a 90 degrees turn. Pneumatic actuator ball valves can be single-acting or double-acting. A single-acting pneumatic actuator uses a single compressed air input to turn the valve and a spring to return the valve to the normal position. A double-acting pneumatic actuator has two compressed air inputs to turn the valve and return the valve to the original position.

 

How does a Pneumatic Ball Valve work?

The most common mechanism for a pneumatic actuator for ball valves is the rack and pinion mechanism. This comprises of the rack (a linear gear) and the pinion (a circular gear). The rack is attached to a piston which is pushed by compressed air to achieve linear motion. This linear motion is converted to circular motion by the pinion. The pinion drives the stem of a ball valve to open and close positions.

To control the pneumatic actuator for ball valves, the compressed air is regulated by solenoid valves. Electrical signals from the controller energize the solenoid valve to either open or close positions allowing compressed air to flow through to both piston sides of the pneumatic actuator. The piston pushes the rack which turns the pinion connected to the stem of the ball valve.

 

Applications of Pneumatic Ball Valves

Pneumatic ball valves are suitable for use across numerous industries that use fluids like water, gas, air, oil and other media. When you buy actuated ball valves, you can use them for any of the following applications:

 

Industrial processes

Chemical handling

Manufacturing

Food and beverage

Wastewater handling

Mining

Municipal treatment facilities

Power plants

Energy refineries

Clean water production

Landfills

Portable water

Swimming pools

Irrigation

Features of Pneumatic Ball Valve:

ZECO pneumatic ball valve can realize remote centralized control, which does not need to waste energy running to the site or climbing to the height at the risk of manual control, greatly reducing the waste of personnel efficiency and ensuring the personal safety of personnel;

ZECO pneumatic ball valve only needs air source to make the ball rotate 90° and small torque to close the valve tightly. The inner chamber of the valve body of exactly the same size as the pipeline passage ensures minimal resistance and reduces energy waste in medium delivery;

ZECO pneumatic ball valve manufacturing experience for many years and international advanced technology combined with the design of the double seal structure, greatly ensure the valve in a variety of pressure conditions of the sealing performance.When the medium pressure runs in the low pressure area, the contact area between the valve seat sealing ring and the ball is small, so there is a larger sealing pressure to ensure the valve seat is reliably sealed.When the medium runs in high position, the contact area between the seat seal ring and the ball valve increases, so the seat seal ring can withstand the greater medium thrust without damage;

ZECO pneumatic ball valve can be selected from various brands of pneumatic actuators to meet the special requirements of customers.
