Browse our high-performance industrial valves engineered for excellence.


Gate valves are widely used in piping systems where dependable shutoff and a clear flow path are required. SVR Global supplies rising-stem and non-rising-stem designs for different installation conditions, pressure requirements and process services. As a Gate Valve Manufacturer in USA, the range covers configurations for industrial, utility and water-handling systems.


What is a Gate Valve?

A gate valve is a linear-motion valve that opens or closes a pipeline by raising or lowering a gate or wedge across the flow path. When fully open, the gate moves out of the fluid stream and creates a relatively unrestricted passage, which helps keep pressure loss low.

Gate valves are mainly used for isolation service and are normally operated in either the fully open or fully closed position. They are not generally intended for continuous throttling, as prolonged operation in a partially open position can increase velocity around the gate and seating surfaces.

Gate Valve Features

• Full-bore flow path with low restriction when fully open

• Designed primarily for positive pipeline isolation

• Rising-stem and non-rising-stem configurations

• Metal-seated and resilient-seated options

• Manual, gear, electric and pneumatic operation

• Flanged, butt-weld and threaded end connections

Why Stem Design Matters

The stem arrangement affects both installation space and how easily valve position can be identified.

With a rising stem gate valve, the stem rises above the handwheel as the valve opens. This provides a clear visual indication of position but requires additional vertical clearance.

A non-rising stem gate valve keeps the external stem height more compact. This makes it useful where space above the valve is restricted or where the valve is installed below ground. Selection between the two designs therefore depends on available space, accessibility and operating requirements as well as pressure and material.
