Ball valves come in two basic designs:
Floating Bail and Trunnion Mounted, with three basic construction variants:
Three piece, End Entry and Top Entry with options of either full or reduced bore designs, Principally designed as an on/off isolation valve for a very wide range of temperatures and pressures they have inherent quick opening flow characteristics.
Specially designed ball valves however, may offer good flow control capabilities at High Pressure. Ail ball valves offer compact actuation due to their rotary quarter-turn operation. Firesafe versions are available for use in the oil and petrochemical industries.

Globe valves are designed for flow control or on/off isolation of fluids.
They are manufactured in straight patterns, angle patterns, oblique patterns and needle designs with a large variety of internal seat construction variants to handle High Pressure flow control duties, A wide choice of metal body options and trims means Globe valves are widely used throughout: industry,
Globe Valve designs consist of O.S. & Y type, Rising Spindle and Bolted Bonnets, The valve comprises of a Solid Rotating Plug Type Disc which is Fine Lapped, Back Seat facilities provides easy replacement of Gland Packing under pressure. Extra deep Stuffing Box Ensures Fluid Tightness, Long Packing life and Low Emissions. We offer Globe Valves with special packings, suitable for thermic fluid temperature up to 425°C.

Check valve is a mechanical device, a valve, which normally allows a fluid to flow through it in only one direction.
Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave. There are various types of check valves used in a wide variety of applications. Although they are available in a wide range of sizes and costs, many check valves are very small, simple, and / or cheap. Check valves work automatically and most are not controlled by a person or any external control; accordingly, most do not have any valve handle or stem. The bodies (external shells) of most check valves are made of metal.
An important concept in check valves is the cracking pressure which is the minimum upstream pressure at which the valve will operate. Typically the check valve is designed for and can therefore be specified for a specific cracking pressure.
