DELCO Valve Manual 3PC Tri-Clamp Sanitary Ball Valves
Manual 3PC Tri Clamp Sanitary Ball Valves
The Manual 3PC Tri Clamp Sanitary Ball Valves, known for its three-piece design, offers several advantages over two-piece valves. It features a partially removable structure, requiring just a 90-degree rotation with minimal torque to achieve a tight closure. Its fully equal valve body interior provides a low-resistance, straight-through flow path for the medium.
Traditionally used primarily for on-off operations, ball valves have evolved to include throttling and flow control capabilities. Their compact structure, ease of operation, and maintenance suitability make them suitable for general working mediums such as water, solvents, acids, and natural gas. They are also suitable for harsh working conditions with challenging mediums like oxygen, hydrogen peroxide, methane, and ethylene.
The main feature of the three-piece ball valve body is its modular design, especially in stainless steel tri-clamp ball valves.

Clamp Ball Valve Key Features:
1, Thrust bearing reduces the friction torque of valve stem, which can make the valve stem operate smoothly and flexibly for a long time.
2, Anti-static function: spring is set between ball, valve stem and valve body, which can lead out the static electricity generated during the switching process.
3, Because PTFE and other materials have good self-lubricating properties, the friction loss with the ball is small, so the ball valve has a long service life.
4, the lower mounted stem and stem head step to prevent stem spray, such as fire caused by stem seal damage, the step and the valve body can also form a metal contact between the stem to ensure stem sealing.
5, small fluid resistance, ball valve is the smallest fluid resistance of all valves, even if it is a reduced ball valve, its fluid resistance is also quite small.
6, good sealing performance of the valve seat, the use of PTFE and other elastic materials made of sealing ring, the structure is easy to seal, and the valve sealing capacity of the ball valve with the media pressure increases.
7, the valve stem sealing reliable, because the valve stem only for seemingly rotating operation without lifting movement, the valve stem packing seal is not easy to destroy, and sealing capacity with the media pressure increases.
