High Pressure Zero Leakage Full Bore Flanged Ball Valve For Petro Chemical Refining
About 2 piece Ball Valve
A ball valve is a stopcock mechanism used to regulate the flow of a pipe fluid and is characterised by having a perforated ball inside as its regulating mechanism.
The mechanism is opened by turning the stem linked to the ball, allowing the fluid to pass by aligning the hole in the ball with the piping. When the valve is closed, the hole lies perpendicular to the line of the piping. The position of the actuator lever indicates whether the valve is open or closed. When the ball valves are totally open they offer a very small pressure drop.
They are also very durable and normally give perfect closing even after years of inactivity. They are also an excellent choice for ON/OFF service. Ball valves have a very wide applications because they are very versatile and can withstand pressures of over 1000 bars and temperatures of over 500°C. They normally measure between 5 mm and 1200mm. They are also easy to repair and handle. Bodies can be made of cast iron, cast steel, stainless steel or alloy. The ball is usually chromed or stainless steel to make it more durable.

The Ball Valves are of a two piece construction and have a solid full bore ball. Relevant design standards are EN ISO 17292, EN 12516, ASME B16.34 and API 608.
Carbon steel (ASTM A216 WCB) and stainless steel (ASTM A351 CF8M) are the materials which form the standard supply. Other materials can be supplied upon request.
A flexible seat design provides tight shut-off at high and low pressures. The special seat construction limits wear to a minimum and ensures low torque values under all operating conditions. Standard seat material is a high grade PTFE TFM1600. Besides the proven mechanical and chemical properties of PTFE, this chemical reinforced version offers suitability for a wider range of applications in respect to pressure and temperature.
