Non Rising Stem Gate Valve Manufacturer in USA
SVR Global is the best Non rising stem gate valve manufacturer in USA and supplies good quality valves in pipeline industries, oil and gas industries and chemical industries in Alaska, San Jose and California. Non rising stem gate valves are a type of valves which are equipped with a stationary stem and are also referred to as Blind Stem Wedge Gate Valves or Rotating Stem Gate Valves.
When the gate is opened or closed, the stem of this valve remains in a fixed position, making it distinct from the Rising Stem Gate Valve, where the stem moves visibly. The Non-Rising Stem Gate Valve is ideal for high pressure and high temperature applications as they require minimal space to operate due to their compact design.
PARTS
· Body: The main outer casing of the valve that houses the internal components.
· Bonnet: top cover of the valve
· Wedge: The part that moves up and down to open or close the fluid flow through valve
· Seat: The sealing surface against which the wedge fits when the valve is closed
· Stem: The component that connects the handwheel or actuator to the wedge, transmitting the force required to open or close the valve.
· Stem nut: The component that engages with the stem to transmit the motion from the handwheel or actuator to the stem.
· Gland: A compression fitting the seals around the stem, preventing leakage from the valve body.
· Packing: A soft material, such as graphite or PTFE, that is used to seal around the stem as it passes through the gland. The packing prevents fluid from leaking out of the valve along the stem.
· Handwheel: The manual control used to open or close the valve.

Applications
· Water supply and treatment: used in water treatment plants, reservoirs, and pumping stations to regulate the flow of water and isolate sections of the system for maintenance and repair.
· Oil and gas industry: used in pipelines, refineries, and other oil and gas processing facilities to control the flow of crude oil, natural gas, and other fluids.
· Power generation: in power plants to regulate the flow of water, steam, and other fluids used in power generation processes.
· Chemical and petrochemical industry: used in chemical and petrochemical processing facilities to control the flow of various chemicals and gases used in manufacturing processes.
· Mining industry: in mining operations to regulate the flow of slurry, water, and other fluids used in mineral processing.
· Fire protection systems: to control the flow of water or other fire suppressant agents used to extinguish fires.
Advantages:
· Excellent shut-off capability: provide a tight seal with low leakage, making them an ideal choice for applications where shut-off capability is critical.
· Low pressure drop: The design of these valves results in low pressure drop across the valve, which minimizes the energy required to move the fluid through the system.
· Bi-directional flow: can handle fluid flow in either direction, making them a versatile choice for a wide range of applications.
· Simple and reliable design: have a simple design, which makes them easy to operate and maintain. They also have fewer moving parts than other types of valves, making them less prone to failure.
· Good flow control: The large gate or wedge in a gate valve allows for precise flow control, making them a good choice for applications that require accurate regulation of fluid flow.
· Can be used in high-temperature applications: suitable for use in high-temperature applications, making them ideal for use in power generation and other industries where high temperatures are common.
