GATE VALVE APPLICATION
Distributor Gate Valve GLT.
Gate Valves are general service valves that can be made in a broad spectrum of sizes using a variety of materials. Gate valves are primarily used to turn on or shut the flow as opposed to regulating flow and are characterized by a traveling wedge, which is moved with the operation of the stem nut. The wedge travels perpendicular to the direction of the flow. Gate valves usually have a minimum pressure drop when fully opened, provide tight shut-off when fully closed, and remain relatively free of contamination build up.

DISC WEDGE
All gates are fully guided to the seats. Gate valves are equipped with flexible 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 SEATING DESIGN
All our gate valves have back seating design. When the gate valve is at fully open position the back seat can seal against the stem.
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 stem during operation or while at position thus allowing for a greater reduction in fugitive emissions. Our standard packings are made of graphite.
END CONNECTIONS
Our valves standard end connection are available in:
- Flange end type with Raised Face (RF), Flat Face (FF) or Ring Type Joint (RTJ) that conform to ANSI B16.5.
- Butt-welding ends (BW) that conform to ANSI B16.25.
- All face-to-face / end-to-end dimensions that conform to ANSI B16.10.
Other special end connections can be supplied according to customer’s requirements.
OPERATOR
Standard valves come in manual operation. Gear operation can be installed in valves if required. Other accessories such as actuators, chainwheels, locking device and many others options are also available to meet customer requirements.
