The pneumatic ball valve is a ball valve with a pneumatic actuator. The pneumatic ball valve specific classification are: stainless steel pneumatic ball valve, plastic pneumatic ball valve, sanitary pneumatic ball valve, carbon steel pneumatic ball valve, two-way pneumatic ball valve, three-way pneumatic ball valve, four-way pneumatic ball valve.
The pneumatic ball valve is a ball valve with a pneumatic actuator; pneumatic actuator execution speed is relatively fast, the fastest switching speed of 0.05 seconds/times, so usually also called quick pneumatic cut-off ball valve. Pneumatic ball valves are typically equipped with various accessories, such as solenoid valves, air source processing triplets, limit switches, positioners, control boxes, etc., to achieve local control and remote centralized control. Thus, the valve can be controlled in the control room, with no need to run to the field or hazardous places to bring manual control, essentially saving human resources and time, and safety.
Pneumatic ball valve has O type ball valve and V type ball valve.
Pneumatic O-type ball valve
It adopts a floating structure; the ball core is precision casting, complicated chrome plating treatment, the valve seat adopts reinforced PTFE material, the flow channel mouth is the same as the pipe diameter, the flow capacity is excellent, the flow resistance is minimal, no leakage when closed, it is generally used as a switch valve, especially for high viscosity.
Pneumatic V-type ball valve
V-type ball valve adopts fixed structure, and the ball core has a V-shaped cut, can V-shaped ball valve has a limited system with V-shaped cutout on the ball core, which can shear media containing fibers and granules. According to the different processes, the equipment can choose pneumatic or electric actuators, pneumatic ball valves, and electric ball valves, where pneumatic ball valves can achieve proportional adjustment, it must be equipped with valve positioner electric ball valves to achieve proportional adjustment must choose electronically, electric actuator or with servo amplifier, etc.
Floating ball
The ball of the pneumatic ball valve is floating under the pressure of the medium. Therefore, the ball can produce a certain displacement and is tightly pressed on the sealing surface of the export end to ensure that the export end is sealed.
The floating pneumatic ball valve structure is simple, with good sealing. Still, the ball body to bear the load of the working medium is all transmitted to the outlet seal, so it is essential to regard whether the sealing material can take the operating burden of the ball medium. This structure is widely used in low and medium-pressure ball valves.
Trunnion Mounted Ball Valve
Q647F/Y trunnion mounted ball valve
Pneumatic ball valves have a trunnion-mounted ball body that does not move when pressurized. The trunnion-mounted ball valve is with a floating seat. By the media pressure, the chair moves so that the seal ring is tightly pressed on the ball to ensure sealing. Usually equipped with bearings on the upper and lower shafts with the ball body, the operating torque is small and suitable for high pressure and large diameter valves. It is more suitable for high pressure and large diameter ball valve.
Resilient Ball Valve
The ball of the pneumatic ball valve is resilient. The ball and seat seal are made of metal materials, sealing specific pressure is very large, relying on the pressure of the medium itself has not reached the requirements of sealing, external force must be applied. This valve is suitable for high-temperature and high-pressure presses.
The resilient ball is resilient by opening a resilient groove in the lower end of the inner wall of the ball. When closing the passage, the wedge-shaped head of the valve stem is used to make the ball rise open and the valve seat compressed to achieve sealing. Release the wedge before turning the ball. The ball then returns to its original shape so that there is a small gap between the ball and the valve seat, which can reduce the friction of the sealing surface and operating torque.
Pneumatic ball valves can be divided into straight-through, tee, and right angles according to their passage position. The latter two types of ball valves are used to distribute the medium and change the flow direction of the medium.

Read this guide to learn about the complete details of a pneumatic ball valve.
One # What Is The Working Principle Of Pneumatic Ball Valve?
A pneumatic ball valve follows the rack and pinion mechanism for its working. It involves a linear gear that is rack and a circular gear that is pinion. The stand is attached to a piston. The primary power source for the pneumatic ball valve is compressed air. A pneumatic valve uses pressurized air and gas to generate energy. The piston is pushed by compressed air to create a linear motion. The pinion converts this linear motion into circular motion. The actuator automates the control of the ball valve. Its ball valve is a quarter-turn off/on the valve that controls media flow through a pivoting ball.

19# How To Prolong The Service Life Of Pneumatic Actuator?
The life span of a pneumatic ball valve depends on the working conditions and medium in which it is installed. The priority thing you have to keep in mind is that you need a stable gas source to increase the service life of a pneumatic ball valve. A stable source of compressed air directly influences the speed of the valve. It also improves the life of the valve sealing ring. Always install a couplet on an individual pneumatic ball valve. It maintains stable air pressure and regularly refuels the cylinders. The couplet discharges moisture from the air that significantly improves the life span of a cylinder.
20# How Many Sealing Positions Does A Pneumatic Ball Valve Have?
A pneumatic ball valve has four sealing positions. The accurately sealed pneumatic actuator increases the life span and functionality of valves. Its sealing positions include:
- Stem Seal Ring: The stem’s position operates. It seals the ring with tetrafluoro or other flexible graphite material.
- Midway Seal Ring: It seals the middle connection valve. Generally, tetrafluoro and graphite metal composite are suitable materials for midway seal rings.
3 & 4. Two Seals On Both Sides: It forms a ball core on both sides of the export seal ring. They are sealed with high-temperature resistant PTFE and PPL materials.
21# What Is Hydrostatic Shell Test?
A hydrostatic shell test validates the mechanical strength and durability of the pneumatic ball valve. A partially open pneumatic valve is mounted on the bench and subjected to hydrostatic pressure. The duration for this test varies from 15 seconds to 300 seconds, depending upon the valve size. It requires operating temperature ranging from 41F to 122F and working pressure up to 15000 psi. The valve is monitored to identify pressure drops during the entire process. If no leakage occurs from the body of the valve, no pressure drop exists. It ensures the functionality, durability, and efficiency of the valve.
