GATE VALVES are most commonly used as shutoff valves in industry today. They are used where minimum pressure drop and bi-directional on-off service is required, and are not designed for throttling service. Prolonged use in the partially open position is likely to damage seating surfaces. Gate valves are available with different wedge configurations (solid, flexible and split) to meet specific service conditions. Normally gate valves are provided with flexible wedges unless otherwise asked for. Valves with class 150lb & 300lb ratings in sizes up to 300m are normally handwheel operated. Sizes 350mm and above in class 150lb & 300lb ratings are gear operated. Class 600lb valves are handwheel operated in sizes up to 200mm and gear operated from 250mm and above. Gate valves can also be fitted with a range of electric actuators

GLOBE VALVES are normally installed with flow and pressure under the plug or disc. These valves are by directional and are used mainly for throttling application. Prolonged throttling at less than 10% open is not recommended due to the possibility of excessive vibration, noise and damage to disc and seats. Where globe valves are being used as a bypass valve, the pressure class rating of globe valve must be at least equal to that of the pipeline or valve where it is going to be installed. Globe valve plug is designed for quick opening but can also be fitted with regulating plug of any configuration to meet specific service condition. Globe valves are normally handwheel operated up to 10” for class 150lb, up to 6” for class 300 and 600. Gear operated from 12” and above for class 150 and 8” and above for class 300 and 600. Valves can be supplied with electric actuators on request.

Cast Steel Double Plate Wafer check valves
| Description: Dual Plate Check Valve Body Materials: A216 GrWCB, A351 GrCF8 Disc Materials: A216 GrWCB, A351 GrCF8 Design Standards: API 6D / API 594/ API598 Size Range: ANSI Class 150 : 2" To 40" ANSI Class 300 : 2" To 24" ANSI Class 600 : 2" To 24" |  |
Compact Wafer Design Extremely light weight and economical compared with traditional flanged type, swing-check valve. The sensitive spring incorporated in the valve closes the valve plate before reverse flow occurs thus preventing water hammer and giving complete pipe line protection even in the high head installations. The valve is compact thus saving space and simplifying installation, and can be installed in any position and at any angle thus allowing rationalized piping layout.
Long Service Life: Dual-check valves incorporate teflon spring bearings to minimize spring wear and assure long service life.
Smooth Operation:Teflon Bearings minimize friction for smooth valve plate operation.
Tight Seal:Shock-easening and tight sealing effect ensured by resilient seat
