We are offering trunnion mounted ball valve. Oswal's trunnion mounted ball valve is the result of innovative engineering. It embodies all the quality, performance, value and safety features required for critical applications. In trunnion mounted ball valve, the ball rotates without moving on the horizontal axis, where as seats are floating and free to move on the same axis. As the pressure increases the force on the seat ring by the pressure pushes towards the ball giving 'bidirectional' sealing. Thrust due to (fluid pressure + spring) both on the upstream and downstream, pushes seat ring towards the ball for positive sealing under all conditions. When the valve is in closed position, the fluid trapped in the body cavity is subjected to thermal expansion and the valve cavity pressure increases. The excessive pressure buildup within the valve cavity is relieved automatically when the pressure inside exceed the spring load on the seat. Internal trunnion reduces the chance of fluid leakage to the atmosphere as in the case of external trunnion mounted ball valves.

We are offering pressure seal valve. Oswal high pressure valves (pressure seal type) offer high performance, reliability and safety. The valves are especially suitable for high pressure and high temperature applications in steam, oil and gas processing, power industry and in the chemical and petrochemical industry. Oswal's high pressure series gate, globe & check valves are the result of development of new technology with uncompromising standards of design excellence, product quality and integrity. Engineered for rigorous performance, and strict manufacturing processes are adhered to in order to maintain consistent compliance to various international standards.

We are offering oswal gate valves. Oswal gate valves are heavy duty, outside screw & yoke type, bolted bonnet, rising stem with non rising hand wheel. Straight through bore design assures minimum turbulence, erosion and resistance to flow. The most advanced design features provides the ultimate in dependable, economic flow control. They are available in wide range of sizes and weights. These are widely suited for high pressure and temperature and variety of fluids. Gate valves are adequate for all service media along with hydrogen service, oxygen service, hydrocarbon service and nace applications. Other optional features like live loading, lantern ring, bleed holes, purging lines and other features are available on request.

We are offering oswal cryogenic valves, except check valves are supplied with extended bonnet with a sufficient gas column length. Usually supplied by the user, to eliminate any chance of frosting of the packing area. The cryogenic valves are installed on applications involving the production, transport and storage of liquefied gases such as oxygen, nitrogen, argon, natural gas, hydrogen or helium down to -254ºc. The cryogenic valves are designed with compliance of asme b16.34 and bs 6364. The cryogenic tests are performed in fully equipped in-house facilities, according to bs 6364.

We are offering oswal check valves are heavy duty, bolted cover, renewable seat ring, and body mounted disc swing type. Valves are straight through flow which works automatically. They are opened by the force of velocity pressure and closed by the force of gravity and back pressure. The valves are single direction flow and restrains flow in opposite direction. Distortion, wear and noisy operation of the valve can be avoided by selecting the size of the valve on the basis of flow conditions. Swing check valves are best suited for moderate velocity operations. Swing check valves are normally designed for horizontal installations. It can be installed in vertical direction with flow in upward under the disc. There is no tendency for seat to gall because the disc meets flat surface without rubbing upon contact. The most advanced design features provides the ultimate in dependable, economic flow control. They are available in wide range of sizes and weights. Flow directions are marked as cast on the body for ease of installation. Swing check valves are adequate for all service media. Valves can also be supplied with counter weights and dash pot arrangement depending upon the condition and request.

We are offering nuclear qualified valves. To meet the country’s growing demand of nuclear qualified valves, ms oswal industries ltd. Has also decided to venture into this field by developing the prototype valve as a technology development project for nuclear qualification i.e. Seismic analysis and tests as per asme qme-1. Scope from nuclear sector to meet country’s energy demand india has decided to go for nuclear power generation in a big way and also drew up an ambitious plan to reach a nuclear capacity of 63000 mwe by 2032 from existing capacity of 5780 mwe. In view of above oswalindustries ltd has decided to venture in to this field by developing proto type valves meeting the requirements of asme qme 1.

We are offering oxygen service valve. The air we breathe contains about 21% of oxygen. Without oxygen we would die within minutes. But even a small increase in the oxygen level in the air to 24% can create a dangerous situvation. It becomes easier to start fire. Pure oxygen under pressure is very reactive. We are the only company in india having full fiedgeg facility for oxygen service valves with clean room & backlight testing facility.

We are offering fugitive emission valve. Most of the focus regarding fugitive emission in valves relates to valve stem packing. Standards such as api-622 type testing of process valve packing for fugitive emission have been established to test valve packing.less attention is paid to the bolted joints in a valve. Valves can have many as five bolted joints-two-end flanges, two body-to-end adapter flanges(for three piece construction) and bonnet flange. These are potentially a significant source of fugitive emissions. One end user has reported 28% of it's emission come from flanged joints.
