Aquaseal Max is a fabricated steel butterfly valve developed as an alternate for cast iron butterfly and sluice valves in water distribution systems. The highly reliable valve also finds application in power plants, utility and fire water lines, and HVAC systems. Customised Aquaseal Max can be used to handle air, gases and vacuum services. The valve has successfully under gone Proof of Design (POD) test as per AWWA C 504 and AWWA C 516.

The key feature of Aquaseal Max Fabricated Steel Butterfly Valve is a Self-energising Disc Seal that uses line pressure to provide assured sealing.

• Specials: Ebonite-lined valves for sea water applications, Special sealing systems for vacuum services, Butt-weld ends

L&T Valves offers glandless Piston Valves for reliable long-term performance in steam, condensate as well as process lines.

The versatile valve can be used for both isolation and throttling applications, and is available with flanged, socket-weld and screwed ends.

• Large effective sealing area - Reliable shutoff(ANSI Leakage Class VI)
• Glandless design - No leakage to atmosphere
• Reinforced sealing rings and Belleville washers - Compensates for thermal expansions, Reliability
• Sealing not affected by presence of dirt or any other impurities in the media
• Online Serviceable - Sealing rings can be replaced without removing the valve from line
• Long service life
• Lower cost of ownership

L&T Valves manufactures a versatile range of Small Bore Forged Steel Gate, Globe and Check Valves. The portfolio comprises valves in T-pattern and Y-pattern, as well as Cryogenic and Bellows-sealed valves. Forged Steel Gate, Globe and Check Valves is available in a variety of materials and end connections to meet customer requirements.

As a standard, valves in ASME classes up to 800 are supplied with bolted body-bonnet joints; for higher pressure classes, screwed joints are offered.

• Rugged construction
• Suited to handle high pressure and temperatures - up to 425 deg C in carbon steel and 540 deg C in alloy steel
• High integrity - Bolted body-bonnet are provided with spiral-wound stainless steel gasket and graphite filler for high integrity sealing
• T-head stem-disc connection of Gate Valve fully meets strength requirements of API 602 and API 598
• High pressure valves are supplied with screwed body-bonnet joint, which ensures ease of inspection and in-line maintenance, and minimises downtime
• Y-pattern design in Globe and Check valves ensures a near-perfect flow which significantly reduces pressure drop and turbulence when compared to conventional designs
• Cryogenic Forged Steel Gate, Globe and Check Valves conform to BS 6364
• Valves can be offered to NACE MR-0175 and other special NACE requirements

• T-pattern and Y-pattern Valves
• Specials: Cryogenic and Bellows-sealed valves
• Material Grades: A105, LF2, F5, F11, F22, F304/ F304L, F316/ F316L, F347, Monel

The DeFlo Mini is one of the most basic type of Desuperheater which utilizes a GFlo Globe Control valve as its cooling water control valve.

It consists of fixed jets arranged to face the steam flow direction through the periphery of the Desuperheater sleeve.

It works well in stable conditions where the steam flow turn-down is a maximum of 4:1.

The Stainless Steel sleeve acts as a thermal liner and is of the size of the steam pipe ID hence eliminating localized velocities created by many competitor designs.

For low turndown applications or in oversized pipes a venturi sleeve can be provided which creates local turbulence and velocity for effective mixing of the water with the steam.

• Fugitive Emissions - Complies to ISO 15848-1: 2006 Class AH leakage
• SIL3 Safety Integrity Level for Automated Valves
• The bellows lifecycle is designed as per MSS SP-117

• Metal bellows seal the moving stem and increase durability of packed stem seal valves
• Bellow provide a barrier between the stem at its point of entry through the pressure boundary and the process fluid within the valve, to eliminate stem leakage
• An anti-rotation device is provided in the bonnet to ensure bellow does not get twisted during assembly and disassembly or by vibration
• Bellow-sealed valves are usually leak tested using a mass spectrometer to detect leakage rates below 1x10E-06 std.cc/sec.
• Bellow-sealed bonnets are backed up with a standard stem packing set and a leakage monitoring port between the bellows and the packing in order to prevent catastrophic release of hazardous fluid in the event of a bellows leak.
