Liberty Valves Private Limited Waliv, Thane, Maharashtra

DESCRIPTION :   Wafer Type Check Valve has short face-to-face dimensions and low weight allows a simple space saving installation between the companion flanges. The valves are suitable to mounting between weld neck or slip on type companion flanges of different standards. They are specially developed for applications where a low-pressure loss is essential. Opening and closing of the valve will take place at an extremely low-pressure difference over the valve disc. The eccentric disc shaft combination with the disc seat guarantees a positive shut off returning media. Wafer check valves are becoming the preferred type of check valve for most applications, due to their compact design. 

DESCRIPTION :   In this type of valves, the check mechanism is the disk which is hinged. The pressure of the fluid lifts the disk and allows the flow. The disk returns to the seat with its own weight. This allows the valve for mounting in horizontal as well as vertical position with upward fluid flow. Check valves are uni-directional valves which automatically open with forward flow and close against reverse flow. They are supplied to meet a wide variety of applications with the closing elements in the piston, swing type. 

DESCRIPTION :   A CLOSED VESSEL WITH CLEANABLE SCREEN ELEMENT DESIGNED TO REMOVE AND RETAIN FOREIGN PARTICLES DOWN TO 0.001 INCH DIAMETER FROM VARIOUS FLOWING FLUIDS.

DESCRIPTION :   A piston valve is a valve used to control the motion of a fluid along a tube or pipe by means of the linear motion of a piston within a chamber or cylinder. It is used for ON/OFF duties.

DESCRIPTION :   Globe valve are closing down valves in which the closure member is moved squarely on and off the seat. In this way the opening of the port is directly proportional to the travel of the disc. This proportional relationship is ideally suited for duties requiring regulation of low rate. Further more the short travel of the disc between the open and closed position makes these valves ideally suited for on-off duties when they must be opened and closed frequently. Globe valves are uni-directional valves and are installed so the fluid pressure is under the disc.

DESCRIPTION :   A butterfly valve is a valve that isolates or regulates the flow of a fluid. The closing mechanism is a disk that rotates.Operation is similar to that of a ball valves, which allows for quick shut off. A butterfly valve is from a family of valves called quarter-turn valves. In operation, the valve is fully open or closed when the disc is rotated a quarter turn. The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid. 

DESCRIPTION :   Ball valves are quarter-turn, straight-through valves that have a round closure element with matching rounded seats that permit uniform sealing stress. The valve gets its name from the ball that rotates to open and close the valve. Ball valves are used in situations where tight shut-off is required. They are wide duty valves, able to transfer gases, liquids and liquids with suspended solids (slurries). Ball valves are durable, performing well after many cycles, and reliable, closing securely even after long periods of disuse. These qualities make them an excellent choice for shutoff and control applications The ball valve's ease of operation, repair, and versatility lend it to extensive industrial use, supporting pressures up to 2500 class.
