Product Description

Product Description

The Stainless Steel Threaded Gate Valve (also known as Stainless Steel Threaded Knife Gate Valve or Stainless Steel Threaded Sluice Valve) is a precision-engineered industrial valve designed for on-off control of fluid/gas flow in pipelines.    Constructed from high-grade stainless steel (e.g., 304/316), it combines corrosion resistance with mechanical strength, making it ideal for harsh environments and critical applications.
Key Features

Material & Construction
Body: Austenitic stainless steel (ASTM A351 CF8/CF8M for 304/316) ensures exceptional resistance to corrosion, rust, and chemical attack.
Trim: Stainless steel wedge disc and stem for reliable sealing and long-term durability.
Seals: PTFE or EPDM gaskets provide leak-proof performance across wide temperature ranges .
Connection & Design
Threaded Ends: NPT, BSPT, or ISO 228 threads for easy installation in small-to-medium pipelines (1/2"-3" or DN15-DN80) .
Non-Rising Stem: Compact design minimizes space requirements, while a visible handwheel indicates valve position .
Full Port: Unobstructed flow path reduces pressure drop, suitable for high-flow applications .
Performance Parameters
Pressure Rating: PN10-PN16 (150-250 psi) or up to 2000 psi for specialized models .
Temperature Range: -30°C to +300°C (-22°F to +572°F), depending on materials .
Standards: Compliant with ASME B16.34, API 598, and ISO 228 for global compatibility .
Working Principle

Operation: A handwheel drives the threaded stem, raising/lowering the wedge-shaped gate to open/close the valve.
Sealing Mechanism: The gate creates a tight metal-to-metal or soft-seat seal when fully closed, blocking flow entirely.    When open, the gate retracts completely into the valve body, allowing unrestricted flow .
Applications

Water Treatment: Suitable for potable water, wastewater, and irrigation systems .
Chemical Processing: Resistant to aggressive fluids (e.g., acids, alkalis) in petrochemical plants .
Oil & Gas: Handles hydrocarbons, natural gas, and oil pipelines under moderate pressure .
HVAC & Industrial Systems: Controls steam, hot water, and compressed air in heating/cooling networks .
Advantages

Corrosion Resistance: Stainless steel withstands harsh environments, extending service life .
Low Maintenance: Simple design reduces wear, requiring minimal lubrication and periodic seal inspections .
Quick Operation: Non-rising stem enables fast on-off control with clear position indication .
Cost-Effective: Competitive pricing compared to exotic alloys like Hastelloy or titanium .
