Ball Valve

Ball valve is a vital component for fluid control in various industrial applications, known for its durability and ease of operation. The range of ball valves offered are as follows:

• Floating Ball Valves: Designed for general applications where tight shut-off is required. These valves are available in various materials such as stainless steel, carbon steel, and alloy steel.
• Trunnion Mounted Ball Valves: Ideal for high-pressure and high-temperature applications, these valves feature a fixed ball supported by trunnions to ensure stability and reduced operating torque.
• Fully Welded Ball Valves: Known for their compact design and suitability for buried or underground installations, these valves minimize potential leakage points and offer enhanced safety.
• Cryogenic Ball Valves: Engineered to withstand extreme low temperatures, these valves are essential in industries dealing with liquefied natural gas (LNG), liquid nitrogen, and other cryogenic fluids.

Ball valves are versatile and widely used across numerous industries. In the oil and gas sector, they are essential for controlling the flow of crude oil, natural gas, and refined products. In petrochemical plants, handling various chemicals and gases efficiently. Water treatment facilities rely on Douson ball valves for regulating water flow in desalination plants, wastewater treatment, and municipal water supply systems. It also critical in power generation plants for steam, water, and fuel handling systems, and HVAC systems for heating, ventilation, and air conditioning applications.

It engineered with precision using high-grade materials such as stainless steel, carbon steel, and other robust alloys. The core of the valve is a spherical ball with a hole through the middle, which rotates to control the flow of fluids. When in the open position, the hole aligns with the flow path, allowing fluid to pass through effortlessly. Conversely, in the closed position, the ball rotates to block the flow, ensuring a secure seal.

They offer both full bore and reduced bore options, catering to different flow requirements. Full bore valves ensure minimal pressure drop, ideal for applications where maintaining flow rate is critical. The advanced sealing technology, including PTFE or PEEK seats, provides a tight shut-off, preventing any leakage and ensuring reliable performance.
