The Stainless Steel Threaded Gate Valve, also known as the Stainless Steel Threaded Knife Gate Valve or Stainless Steel Threaded Sluice Valve, is meticulously crafted for precision control over fluid and gas flow within pipelines. Constructed from premium-grade stainless steel such as 304 or 316, it blends unmatched corrosion resistance with robust mechanical strength. This makes it the ideal choice for demanding environments and vital applications, ensuring reliable performance and longevity.
Key Features
Material & Construction
Body: Fabricated from austenitic stainless steel (ASTM A351 CF8/CF8M for 304/316), this valve body guarantees remarkable resistance to corrosion, rust, and chemical degradation, ideal for long-lasting applications.
Trim: Equipped with a stainless steel wedge disc and stem, providing dependable sealing capability and enduring durability for extended lifecycle use.
Seals: Utilizing PTFE or EPDM gaskets, the valve ensures leak-proof performance across a vast temperature spectrum, enhancing its versatile application potential.
Connection & Design
Threaded Ends: Available with NPT, BSPT, or ISO 228 threading, this design facilitates straightforward installation in pipelines ranging from small to medium sizes (1/2"-3" or DN15-DN80).
Non-Rising Stem: The compact design minimizes spatial demands, with a clearly visible handwheel to convey valve position, enhancing operational convenience.
Full Port: Designed with an unobstructed flow path, this feature minimizes pressure drop, rendering it perfect for high-flow scenarios.
Performance Parameters
Pressure Rating: Offers a range of PN10-PN16 (150-250 psi), with certain specialized models accommodating up to an impressive 2000 psi.
Temperature Range: Operating efficiently from -30°C to +300°C (-22°F to +572°F), contingent on material selection, ensuring versatility across various environments.
Standards: Meticulously crafted to comply with ASME B16.34, API 598, and ISO 228 standards, ensuring global compatibility and trust.
Working Principle
Operation: The manual handwheel maneuvers the threaded stem, which, in turn, elevates or lowers the wedge-shaped gate to effectively open or close the valve as needed.
Sealing Mechanism: When fully closed, the gate establishes a robust metal-to-metal or soft-seat seal, effectively halting flow. When opened, it retracts entirely into the valve body to permit unrestricted flow.
Applications
Water Treatment: Versatile for potable water, wastewater, and irrigation systems, ensuring optimal water management.
Chemical Processing: Resilient against aggressive fluids like acids and alkalis, making it indispensable in petrochemical processing plants.
Oil & Gas: Efficiently manages hydrocarbons, natural gas, and oil pipeline applications under moderate pressure conditions.
HVAC & Industrial Systems: Expertly controls steam, hot water, and compressed air within heating and cooling networks.
Advantages
Corrosion Resistance: The stainless steel construction offers unparalleled durability in harsh environments, significantly extending the service life of the valve.
Low Maintenance: Its straightforward design reduces wear, requiring only minimal lubrication and sporadic seal inspections, optimizing maintenance efforts.
Quick Operation: The non-rising stem design allows for rapid on-off control with a transparent position indication, enhancing operational efficiency.
Cost-Effective: Offers a competitive price point compared to more exotic alloys like Hastelloy or titanium, delivering substantial value.

Installation & Maintenance
Installation: To guarantee optimal performance, carefully ensure that all threads are impeccably clean and well-lubricated. Exercise caution to avoid over-tightening, as this could potentially cause damage to the valve's components.
Maintenance: Keep your Manual Control Gate Valve in prime condition by following these essential steps.
Regularly inspect seals and packing for wear: Conduct routine checks to detect any signs of wear and tear on the seals and packing, ensuring they remain in perfect working order.
Lubricate stem threads and bearings to reduce friction: Apply a high-quality lubricant to the stem threads and bearings. This reduces friction, ensuring smooth operation and extending the lifetime of your valve.
Perform pressure tests periodically to verify integrity: Schedule regular pressure tests to confirm the valve's integrity and guarantee that it continues to function efficiently, particularly in water treatment applications.
