Clamped Ball Valve

Clamped Ball Valve

A ball valve is a valve equipped with a spherical disc which is used to regulate the flow of the fluids. Clamped ball valve is the ball valve with two-position handle to control the flow of viscous liquids. The liquids usually contain solid particles, and clamped ball valve aims to ensure an unblocked flow. This kind of ball valve can be used in various areas, including food processing, beverage production and chemical industry and so on. The structure of clamped ball valve is ball and the power to open or close the valve is manual. Therefore, the operation can be controlled by people flexibly. Some clamped ball valves are also powered pneumatically. In order to maintain the operation safety, clamped ball valve must be used under medium pressure and normal temperature.

Generally speaking, clamped ball valve is made of stainless steel. However, the materials to make the parts of clamped ball value should be precise. For example, according to the concrete size, the ball is made of AISI 304L or AISI 316L, and the clamp must be made of AISI 304L. According to the FDA 177.2600, gasket must be made of EPDM. The design of clamped ball valve is rather compact and robust. The Ra of internal surface finish should be equal to or less than 0.8μm and the external surface finish should be strictly machined. Clamped ball valve has diverse varieties, and it can be one-piece, two-piece or three-piece. The size can also be various. The diversity can meet the different demands of different clients.
