Allines Sand Casting Gate Valve

Avail from us premium quality Sand Casting Gate Valve in a wide variety of specifications. We are a well-known Sand Casting Gate Valve Manufacturer, Exporter and Supplier based in India. The Sand Casting Gate Valve moves linearly, perpendicular to the direction of flow. Our Sand Casting Gate Valve is generally used in the fully opened or fully closed position. Also, Sand Casting Gate Valve is used where minimum pressure drop and bi –directional on – off service is required.
Flexible Wedge :

• A one-piece cast flexible wedge ensures tight Seat rings over a wide range of differential pressure and temperatures
• Compensates for deformation of body due to pipe stresses
• Will not stick when valve is closed hot and allowed to cool

Seatrings :

• Screwed seat-rings, bottom seated type lapped on both sides
• Seal Weld seat-rings prevents leak proof path between the seat-rings and body. This design is superior to screwed seats which can loosen up due to temperature fluctuation / corrosion or vibration and results in leakage

Cryogenic Service :

• Extended bonnet with vapor column length according to BS 6364. Vapor column allows the stem packing to be functional by keeping it away from the cryogenic fluid
• BY - Pass Arrangement
• A By-Pass arrangement service to purposes : In steam services, to warm up the line before opening of the main valves.(2)In steam and other lines, to balance the pressure on both sides of the main valves wedge or plug to bring down the valve opening torque

Lantern Rings :

• To prevent escape of service fluid to atmosphere
• This finds applications in stringent environment conditions or in the case of potentially harmful to service fluids

Locking Devices : Locking devices are used to secure a hand wheel in a fixed position to prevent accident or authorized operation of valves
Chain Wheel Positions : Chain wheels are used for the valves located too far above the floor for convenient hand wheel operation

Salient Features :
