We offered Swing Check valves are manufactured to API Std. 6D and API Std. 600, and tested to API Std. 598. Swing check valves are used to prevent flow reversal in piping systems. They are suitable for service in horizontal or vertical (flow up through valve only) piping tuns. Swing check valves have low pressure drop and are best suited for moderate velo0city applications. Body Its spherical form of large radius allows for the stresses. turbulence and resistance to flow to be kept to a minimum. BODY-BONNET JOINTS Body-Bonnet Joints of check valves are machined as follows : On 150 and300 classes ; male and Female. On 600, 900 and 1500 classes : RTJSeat Rings Seat ring are manufactured in two different ways, depending on the class and type of valves: 1) Screwed seat rings, bottom seated type lapped on both side. They are dry assembled, with a controlled torque setting to t body. 2) Welded-in seat rings, designed in order to prevent any turbulence and avoid damages due to corrosionBoth are forged or rolled in one piece, for all dimensions. They are heat treated to obtain the requested surface hardness, and are perfectly cleaned before assembling.Insert Seat RingsThese rings are manufactured with teflon or viton inserts, depending on fluid and service conditions. They provide an elastometer primary seal. combined with a fire sale metal to-metal secondary seal, for temperatures from - 100oC (-144oF) to 204.4oC (400F).Where maintenance is a potential problem the viton insert is in the form of a toroidal ring so that it can easily be removed END CONNECTIONS Our standard production covers valves with : Flanged ends (RF) that conform to ANSI B 16.5 and face to face dimensions that conform to ANSI B 16.10, with a raised face serrated finish or, on request, with any other of finish. Butt-welding ends (BW) with end to end dimensions that conform to ANSI B 16.10. Customer must specify the type of schedule required, or class of pipe, or diameter and bore. Ring-joint flanged ends (RTJ) that conform to ANSI B16.5, with end to end dimensions ANSI B 16.10 Other Special end connections are supplied to customers’ special requirements. Special Constructions A) Outside lever and weight     On request swing check valves can be furnished with an outside lever and weight. The object of the lever and On weight is either to balance the disc or give it     added weight. In balancing the disc the valve will open with a minimum of pressure. When the disc is weighted the valve will be very sensitive to a reversal of     flow.B) Dashpot feature     In case of intermittent use or in presence of thrusts, dashpot feature is highly recommended.     In such instance the dashpot feature gradually causes the opening and closing of disc preventing therefore dangerous shocks. C) Check valves with pneumatic safety control     This is in the form of a simple pneumatic piston. In normal conditions of use, it pushes up the lever, thereby moving a special cam, that allows the disc to     move.    Should there be no air in the cylinder, the spring allows the lever, and hence the disc to descend, thereby assuring that encloses before any inversion of flow.

Ball valve opens by turning a handle attached to a ball inside the valve. The ball has a hole, or port, through the middle, so that when the port is in line with both ends of the valve, flow will occur. When the valve is closed, the hole is perpendicular to the ends of the valve, and flow is blocked. The ball, which can make a quarter turn (90°) around the spin axis, is the on/off control of the Ball valve. Ball valves in the piping are used to cut, distribute and change the flow direction of the fluid. If the opening were designed to be V-shaped, it would also have the excellent function of flow control. Ball valves, which need a little rotating force and turn a quarter, can be closed tightly. The completely equal lumen provides a littler-resistance "green passage". Ball valve not only has the advantages of simplicity in system structure and good performance in sealing Properties, but also smaller in size, less in weight, less material, smaller dimension, less drive torque, easy-operating, easy-repaired, can be applied to general media, such as water, solvent, acid and natural gas. It still can be used in poor working conditions, such as oxygen, hydrogen peroxide, methane, ethylene and so on. The body of ball valves can be a whole or a combined one. Ball valves are widely used, the demand of quantity is still growing up, and the current trend is to develop high-temperature, high pressure, heavy caliber, high tightness, long life-span, excellent adjusting performance and multi-function valves. The reliability and other performance indexes are all reached a comparable high level, and ball valves have partly replaced gate valves, globe valves and throttle valves. Due to the outstanding advantages of the ball valves, it has been widely used in the areas of aerospace, Petroleum, long-distance pipeline, light industry and food industry, construction and so on.
