Product Description

Instead of a manual handle operation to turn the valve on or off, some valves can be fitted with an electric or pneumatic actuator. They connect directly to the valve stem and are capable of turning it a quarter turn. The most common flange connection between the valve and actuator is the ISO 5211 standard. Figure 4 shows an example of an ISO 5211 top ready to be connected to an actuator. By using an actuator, you can control your ball valve remotely or through a controller so that it can be used as an automatic shut off. A spring actuated ball valve, also called spring loaded, use a spring to open/close the valve in a power-off scenario and an actuator to then hold it in the open/close position. These are used for energy conservation applications or for fail-safe reasons.

• Forged ball valves are strong and durable, and these valves can be used in particularly demanding situations that involve high temperatures and pressures.
• The forging process reduces the ball valve's susceptibility to issues like porosity, cracking, and shrinkage.
• Forged ball valves can adapt to temperature changes very quickly; Therefore, these valves are suitable for operation in multiple environments.
• Low maintenance needs

To understand the working principle of a ball valve, it is important to know the five main ball valve parts and 2 different operation types. The 5 main components can be seen in the ball valve diagram in Figure 2. The valve stem (Figure 2 labeled A) is connected to the ball (Figure 2 labeled D) and is either manually operated or automatically operated (electrically or pneumatically). The ball is supported and sealed by the ball valve seat (Figure 2 labeled E) and their are o-rings (Figure 2 labeled B) around the valve stem. All are inside the valve housing (Figure 2 labeled C). The ball has a bore through it, as seen in the sectional view in Figure 1. When the valve stem is turned a quarter-turn the bore is either open to the flow allowing media to flow through or closed to prevent media flow.

The actuator of a high-pressure forged ball valve is the mechanism responsible for opening and closing the valve, allowing for remote or automated control of fluid or gas flow.

High-pressure forged ball valves can be equipped with various types of actuators, depending on the application requirements and the level of automation desired. Common types include:

Manual Actuators: These actuators require human intervention to operate the valve, typically through the use of a handwheel or lever. Manual actuators are simple, reliable, and well-suited for applications where infrequent operation or precise control is necessary.

Pneumatic Actuators: Pneumatic actuators use compressed air to actuate the valve, converting the energy of the air into mechanical motion to open or close the valve. They offer rapid response times and are commonly used in industrial automation applications where quick valve operation is essential.

Electric Actuators: Electric actuators utilize electrical energy to open and close the valve, often through the use of an electric motor. They offer precise control and can be integrated into automated systems with ease, making them suitable for applications requiring continuous or remote operation.

Hydraulic Actuators: Hydraulic actuators use hydraulic fluid to generate mechanical force and operate the valve. They are known for their high force output and are commonly used in applications where high-pressure operation or heavy-duty valve actuation is required.
