Double lock release ball valve, ball valve

Product Overview of Double Locking Relief Ball Valve:

The double locking relief ball valve is a dual-sealing and dual-discharge ball valve that has two valve seat surfaces when in the closed position. It locks the flow at both ends of the valve (there is a middle cavity between the two valve seat surfaces through which the exhaust port is connected to the valve body for venting). It is a valve with two balls installed on one valve, which can be opened and closed simultaneously, or one open and the other closed, achieving both blocking and discharge functions. It replaces the complex form of multiple valves connected in series in traditional pipelines, reduces leakage points in the pipeline system, and realizes rapid discharge and closing functions. The end of the valve body can be processed into different connection methods such as flange end, NPT thread end, socket welding end, and butt welding end according to different needs. 

Advantages of the double-locking relief ball valve:

The double-locking relief ball valve is opened or closed by rotating the valve stem. It can be switched at a 90-degree angle. It is lightweight, has a small size, can be made in large diameters, has reliable sealing, a simple structure, is easy to maintain, and the sealing surface and the spherical surface are often in a closed state, which is less likely to be eroded by the medium. It is particularly suitable for natural gas and oil transportation pipelines.

The double-locking relief ball valve is operated by rotating the valve stem to open or close the valve. It has a 90-degree angle of rotation and is lightweight, compact. It can be made in large diameters. The sealing is reliable, the structure is simple, and maintenance is convenient. The sealing surface and the spherical surface are often in a closed state, making them less prone to erosion by the medium. It is particularly suitable for natural gas and oil transportation pipelines.
