Gate Valve Manufacturer in USA – SVR Global

SVR Global is a recognized Gate Valve Manufacturer in USA, offering a comprehensive range of industrial-grade gate valves engineered for reliable isolation across critical applications. Designed in accordance with API 600, API 602, API 603, ASME B16.34, and AWWA C500 standards, our valves ensure dependable shutoff in pipelines carrying water, oil, gas, steam, and slurries.

Function & Working

Gate valves operate on a linear motion mechanism, where a wedge, knife, or slab disc moves perpendicular to the flow to provide either complete shutoff or full flow with minimal pressure drop. This design makes them ideal for on/off services rather than throttling.

Advantages

Minimal pressure loss due to unobstructed bore
Bi-directional sealing capability
Suitable for high-pressure and high-temperature service
Wide material selection for corrosive and abrasive media
Easy maintenance with bolted bonnet and replaceable seats

Types Offered

Rising Stem Gate Valve (OS&Y) – Stem rises with handwheel rotation, ideal for visual indication of valve status
Non-Rising Stem Gate Valve (NRS) – Compact design for underground and confined space applications
Knife Gate Valve – Designed for slurry, pulp, and abrasive media service
Resilient Seated Gate Valve – Common in water and wastewater industries, provides bubble-tight shutoff
Pressure Seal Gate Valve – Heavy-duty design for high-pressure and temperature service
Parallel Slide Gate Valve – Suitable for steam service with tight sealing under thermal variations
