The Split Body Side Entry Ball Valve, available in either API 6D or API 6A design, boasts a robust construction with two or three pieces joined together using a bolted execution. It features a trunnion mounted design with plate support, ensuring stability and durability. The valve incorporates spring energized floating seats, which not only provide a secure seal but also enable self-relieving or double piston effect functionality. Furthermore, it offers double block and bleed capability to enhance safety and control. The Anti Blowout Stem feature ensures that the stem remains securely in place, preventing any unintended removal during operation. Additionally, an antistatic device is included to mitigate the risks of static discharge. Overall, this valve guarantees superior performance and reliability in demanding industrial applications.


Ball and seats are implanted with a tungsten carbide coating, resulting in a metal-to-metal seated component that is hardfaced.

Depending on the specific design, the valve can be operated manually using a lever or gear, or activated by various types of actuators such as pneumatic, hydraulic, or electric. The choice of actuation method depends on factors such as the type of fluid or gas being controlled, the required precision and speed of operation, and the availability of power sources.
In manual mode, the operator can use a lever or gear mechanism to turn the valve stem, which in turn rotates the valve disc or ball to open or close the flow path. This method is simple and reliable, but requires physical effort and may not be suitable for large or fast-acting valves.
In contrast, actuators can provide more force and control over the valve position, using compressed air, hydraulic fluid, or electricity. Pneumatic actuators utilize the energy of compressed air to drive a piston or diaphragm, which applies force to the valve stem or actuator arm. Hydraulic actuators use a similar principle, but with pressurized fluid instead of air. Electric actuators convert electrical energy into mechanical motion using motors, gears, or other components, and can be controlled remotely or automatically.
The choice of actuator depends on the specific requirements of the application, such as the available power source, the cost and complexity of the system, and the desired response time and accuracy. Some valves may also have multiple actuation options, allowing for manual adjustment as well as remote or automatic control. Overall, the actuator type and mode of operation play a crucial role in the performance and reliability of the valve system, and should be carefully selected based on the application requirements.

Our in-house engineering team has successfully developed a Side Entry valve design that is completely original and meets stringent safety standards. Depending on the use of a partial stroke function actuator, our design is certified as SIL2 or SIL3 qualified. We take pride in our ability to engineer and deliver high-quality solutions that prioritize safety and reliability.


API 6D and API 6A offer a broad range of size options, ranging from small to large diameters. For API 6D, the available sizes range from half an inch to 42 inches, while for API 6A, the sizes extend from 1 13/16 inches to 13 5/8 inches. The wide array of size options ensures that users can find the appropriate product to suit their needs and requirements. Whether it's for industrial or commercial purposes, API 6D and API 6A provide reliable and efficient products that are designed to meet the highest standards in the industry.

Precision Machined Forged Body

High pressure, critical applications are secured through precision finish machining, which maintains tight tolerances. The forged body is crucial in eliminating any potential leakage caused by substandard castings. This meticulous process ensures a secure assembly that is highly reliable.

Ball/Seat Lapping

When the seats are lapped to the ball, tight tolerances are achieved, leading to enhanced shut-off sealing ability and reduced torque demands.

Guided Seat Design

Flexibility in materials of construction, customizable spring configurations, and ease of maintenance are all key features of the guided seat design. This design allows for different materials to be used for the end closures, seats, and body, depending on the specific requirements. Additionally, the spring configurations can be tailored to achieve specific pressure relief set points, providing precise control in various applications. Moreover, the guided seat design ensures better concentricity between the sealing components, leading to improved sealing performance. By rearranging the original content, we can emphasize the different aspects of this design while maintaining the overall information.
