Product Description
What is a Non-Rising Stem Gate Valve?
A Non-Rising Stem Gate Valve is a type of rotary valve used to regulate flow through pipes. It consists of a circular disk (or “butterfly”) that pivots on its center axis to open or close the flow path inside the valve body.
Materials of Non-Rising Stem Gate Valve
- Body: Typically constructed from ductile iron, cast steel or aluminum to withstand pressurized systems and corrosion.
- Disk: Available in aluminum bronze, ductile or nodular irons as they are corrosion resistant and provide tight shut-off.
- Seat: The sealing surface is made from resilient materials like EPDM, NBR or FFKM rubber optimized for temperature, chemical compatibility and long life.
Benefits of Non-Rising Stem Gate Valve
- Prevent Backflow – The primary benefit is avoiding contamination of fluid source from back-siphoning or backpressure flows that could introduce unwanted materials.
- Flow Security – Non-return functionality gives confidence in downstream pressures without risk of reverse surge loads damaging pipes, tanks or equipment.
- Self-Acting Operation – No external power is required as valves from High Quality Non-Rising Stem Gate Valve Manufacturers, automatically open and close based on differential pressures across the seat.
- Durability – Engineered valve designs withstand millions of pressure cycles without compromising barrier performance over decades of use.
Applications of Non-Rising Stem Gate Valve
- Water Treatment: Extensively utilized for flow regulation in municipal, industrial, and coastal desalination plants.
- Power Generation: Commonly found in the heating and cooling systems of power stations, refineries, and manufacturing facilities.
- Oil & Gas Industry: Frequently specified for pipelines in drilling rigs, refineries, and LNG/LPG terminals due to their bi-directional capability.
- Mining Sector: Employed in handling mineral slurries, sludge streams, and chemical flows within gold, copper, and coal extraction processes.
- Chemical Applications: The availability of elastomer seat options and suitable body materials make Non-Rising Stem Gate Valve a top choice for the chemical, food, and plastics industries.
- Maritime Usage: Specially coated valves exhibit resilience to seawater intake and are perfect for ballast and bilge applications on ships, offshore rigs, and remote platforms.
