Gate Valves
Raj Metals provides a robust range of Gate Valves, engineered for reliable isolation in liquid and gas piping systems. Designed with a sliding wedge that moves perpendicular to the flow, our gate valves ensure minimal pressure drop and a completely unobstructed flow path when fully open. Whether you require Bolted Bonnet, Pressure Seal, or Forged Steel gate valves, our products are manufactured to provide a tight leak-proof seal and long-term durability in high-pressure, high-temperature industrial environments.
Key Features
✓ Unobstructed Flow & Low Pressure Drop
✓ Bi-Directional Leak-Proof Sealing
✓ Superior Corrosion Resistance (SS 304/316)
✓ Ideal for Harsh Chemicals & High Temps
