Shreeraj Industry

Gandhinagar, Gujarat

Shreeraj Industries cast steel valve are designed and manufactured to meet or exceed API 6D Standards and are highly dependable and easy to maintain. Check Valve are ideally suited for applications where back flow of the fluid is not desired.

Size Range: 2 12 (50 300 mm) Pressure Rating: 150 1500 Class

Standard Connections: Flanged End FIRE SAFE DESIGN TO API 6FD

• Full open and Pig- able
• Replaceable SS Trim
• Integral or Replaceable Seat available
• NACE MR 0175 ( REV. 2002)
• Bolted Bonnet with Tap and Plug.

Shreeraj Industries manufactures a range of API 6A Gate Valves. The rugged design ensures reliable and trouble free service. The valves are of full bore design with an expanding gate feature to provide positive shut off on both upstream and downstream seats.Shut-off is achieved by a parallel wedging action of the two gate segments which mechanically brings the gate and seat into metal to metal sealing contact. The seats have non-metallic inserts, which serves as wiper to keep the gate faces free from solids. The sealing is not affected by pressure variations or vibrations.Shut-off is achieved by a parallel wedging action of the two gate segments which mechanically brings the gate and seat into metal to metal sealing contact. The seats have non-metallic inserts, which serves as wiper to keep the gate faces free from solids. The sealing is not affected by pressure variations or vibrations.

The body cavity can be lubricated through fitting to ease operation and resist corrosion. The valve can also be repacked while under pressure. In case of need, seals and seats can be removed and replaced without removing the valve body from the line.

For remote operation, valves can be fitted with electric or pneumatic actuators.Produced in sizes from 2.1/16 inch to 4.1/16 inch with rated working pressure up to 5000 PSI, the valves are offered with flanged or threaded ends. Body, bonnet and trim materials can be offered to meet NACE.

TIGHT AND POSITIVE SEAL:The valves adopt expanding gate operating principal to give a tight and positive seal against both upstream and downstream seats under a wide range of pressures and environmental condition.

FULL FLOW:The full round bore (Through Conduit) design allows the fluid to flow through the valve smoothly without causing turbulence and minimize pressure drop. The absence of surface cavity eliminates the accumulation of foreign matter and allows passage of tools through thevalves.

LOW OPERATING TORQUE:Superior packing and thrust bearings reduces the torque.

LONG SERVICE LIFE:Coating of molybdenum disulfide on the gate, segment and stem part provides low friction protective shield, which also guards against certain type of corrosion. Seat is fully protected from blow, in both open and close position and also because of their large seating area they give exceptionally long service life.

TWIN SEAL PROTECTION:The valves incorporate reinforced PTFE seats, which give simultaneous seating action against upstream and downstream sides.

ONLINEREPAIR ABILITY:Online replacement of seals and seats is possible and stem packing can be added to the packing box while the valve is under pressure.

The Valves are available in different pressure ranging from ANSI class 150 to class 2500 (PN 20 to PN 420), sizes from 2 to 24 (50 mm to 600 mm) with either Flange ends or Butt-weld ends.Operation of these Valves can be Manual, Geared or Motor Actuated.

The seats have non-metallic insert, which serve as wiper to keep the gate face free from solid. The sealing is not affected by pressure variation or vibration.

Parallel expanding gate design can be provided for mechanical seal between seat and gate ensuring valve integrity at both high and low line pressure, which allows the body cavity to be bleed in close position.

FEATURES

FULL FLOWFull Round Bore (Through Conduit) design allows the fluid to flow through the valve smoothly without causing turbulence and minimize pressure drop. The absence of surface cavity eliminates accumulation foreign matter and allows passage of tools through the valve.

PROTECTION AND LONG LIFE SEATS:Seat is fully protected from blow, in both open and close position and also because of their large seating area they give exceptionally long service life.

ONLINE REPAIR ABILITYOnline replacement of seal and seat is possible, the valves can also be repacked while under pressure.

BLOCK AND BLEEDThe slab gate design utilizes two floating seats, which are pressure energized, moving the upstream seat in contact with the Gate and subsequent application of line pressure to the Valve bring about a tight and complete seal with both upstream and downstream. This two way seal is ideal for Block and Bleed.
