Specialityvalve is the prominent Double Block and Bleed Ball Valve Manufacturer in India. Double block and bleed valve is made up of two ordinary ball valve which linked by common inlet end. The double block and bleed ball valve is a product designed to replace multiple connections between ordinary valves; it is a double block and bleed ball valve, as the name implies. The difference between this DBB valve and others is that it can effectively overcome leakage that occurs during system operation, and it can be swiftly closed and discharged. It is defines a single valve with two seating surfaces that, in the closed position, provides a seal against pressure from both ends of the valve with a means of venting/bleeding the cavity between the seating surfaces. This valve does not have positive double isolation when only one side is under pressure. Double block and bleed valve is also defined as closure of a line, duct, or pipe by shutting and locking or tagging two inline valves and opening and locking or tagging a drain or vent valve in the line between the two closed valves. Double Block and Bleed Ball Valve Manufacturer in India comes with very different type of ball valve to provide easy service to the customers. Advantages of Double Block and Bleed Ball Valve: • Sealing against the valve's upstream and downstream ends • Design is compact. • Operational safety • For a negligible pressure decrease, uninterrupted flow is required. • Prevents contamination of the product. • Leakage pathways are being reduced. Double Block and Bleed Ball Valve used in many industries like: • Energy industry • Petrochemical industry • Oil & Gas industry • Chemical industry Description: Body Material: Cast iron, WCB, WCC, WC6, LCC, LCB, SS304, SS316, CF8, CF8M, F55, F51, F53, ASTM, A105.

Floating ball valve most commonly used in piping industry. This valve plays an important role in regulating the flow of medium through the pipelines. The valve create a bi-directional seal. It is customized for high pressure operations. Normally they are used in pipelines with low to medium pressure. Floating ball valve featured a ball shape disk which is hallow and perforated, so that liquid can pass through it when it open. Working of Floating Ball Valve: Floating ball valve gets its name from the hallow, ball like sphere which floats inside the valve’s body. That is compressed between two flexible seats while suspended in liquid. During operation, floating ball vall just float slightly downstream, which cause the sealing mechanism compressed under the ball. This ball floats to the metal stem to seal it, which provides the failsafe under the design. The stem in the valve’s body connects to the top of the ball and allows the ball to rotate 90 degrees. Also this stem allows the ball to move laterally when the pressure arises upstream acts on it, while the downstream seat improves the tightness of the valve’s seal. When liquid flows in either direct this operation allows the valve to get closed. Types of Floating Ball Valve: • Cast floating ball valve • Forged floating ball valve Floating Ball Valve is used in industries like: • Oil & Gas Industry • Gasification Industry • Compressor station • Filter and drying system Advantages of Floating Ball Valve: • It has compact design • It is customizable • It has reliable sealing functions • Uncompecated stucture • Cost effectiveness Description: Body Material: Cast steel (WCB, WCC, WC6, LCC, LCB), Stainless steel (SS304, SS316), Carbon steel(CF8, CF8M), Alloy 20, Hastelloy Class: 150 to 2500 Pressure: PN10 to PN450 Size: ½” to 48” End: Buttweld, Socketweld, Threaded, Flanged Visit: https://www.specialityvalve.com/product-category/floating-ball-valve/
