3-PIECE FLOATING BALL VALVES

D Valve 3-piece construction floating Ball valves are designed, manufactured and tested as per international standards. The quality is ensured from the receipt of components till the dispatch of the valve to the customer. Its robust design and simple construction guarantee a long working life and low maintenance. The internals of our entire 3-Piece socket/threaded end ball valves of Class 800# can be replaced without removing the valves from the pipeline. This reduces the maintenance time. All our three-piece floating ball valves are offed with manual hand lever/wrench operated by the standard. Any kind of operation mechanism like Electric/Pneumatic/Hydraulic actuators can be offered upon request to meet customer requirements.

CAVITY FILLER SEAT BALL VALVES

The cavity filler seat is used mainly in the Biopharma and pharmaceutical industries. The design minimizes crevices and gaps between the ball and the valve body, thus reducing the risk of trapped contaminants. Because the valve body is specially machined with a larger bore diameter to fit the special cavity filler seat dimensions, they cannot be retrofitted into a standard valve body. The cavity filler seat is a one-piece seat-seal design and is therefore suitable for use with the D Valve 3-piece product line. Note: A valve with a cavity filler seat cannot be used in fire-safe service.
