Gate Valves
Manufacturing Standards
General Design : API 600 / API 6D / API 603
Face To Face : ASME/ANSI B16.10
Flange End : ASME/ANSI B16.5 & B16.47
Butt Weld End : ASME/ANSI B16.25
Pressure Rating : ASME/ANSI B16.34
Fire Safe Design : API 6FA
Inspection & Test : API 598 / API 6D
Feature : Bolted Bonnet, Outside Screw & Yoke, Rising Stem,Flexible Wedge
Disc Wedge
All gates are fully guided to the seats. Gate valves are equipped with fl exible wedge disc.
Seat Ring
Seat rings are designed to greatly reduce and/or prevent any turbulance to avoid damages due to the corrosion. Seat rings for gate valves are typically made from forged steel.
Back Seat Design
All our gate valves have back seating design. When the gate valve its at fully open position the back seat can seal againts the steam.
Stem
The stem connection to the gate is of T design, which is forged integral with the stem. The stem to gate connection is designed to prevent the turning of the disengagement of stem from the wedge while the valve is in service.
Packing
The stem packing is designed and arranged to ensure a maximum seal along the steam during operation on while thus allowing for a greater reductions in fugitive emissions. Our standard packings are made of graphite.
End Conection
Our valves standard end connections are available:
- Flange end type with Raised Face (RF), Flat Face (FF) or Ring Type Joint (RTJ) that conform to ANSI B16.5. B16.25.
- Butt welding ends (BW) that conform to ANSI b16.25.
- All face-to-face / end-to-end dimensions that conform to ANSI B16.10. according to customer’s requirements.
Other special end connections can be supply according to customers requirements.
Operator
Standard valve come in manual operation. Gate operation can be installed in valves if required. Other accessories such as actuator, chainweels, locking device and many others options are also available to meet customer requirements.
