Introducing the Stainless Steel Threaded Gate Valve, a marvel of engineering precision, also referred to as the Stainless Steel Threaded Knife Gate Valve or Stainless Steel Threaded Sluice Valve. This industrial-grade valve is meticulously crafted for impeccable on-off control of fluid and gas flows within pipelines. Constructed from premium-grade stainless steel, such as 304 or 316, it offers an exceptional blend of corrosion resistance and mechanical strength, perfectly suited for demanding environments and critical applications.
Key Features
Material & Construction
Body: Crafted from austenitic stainless steel (ASTM A351 CF8/CF8M for 304/316), ensuring superior resistance against corrosion, rust, and chemical assaults.
Trim: Features a stainless steel wedge disc and stem, promising reliable sealing and exceptional long-term durability.
Seals: Equipped with PTFE or EPDM gaskets, these valves ensure a leak-proof performance across an extensive range of temperatures.
Connection & Design
Threaded Ends: Available with NPT, BSPT, or ISO 228 threads, facilitating effortless installation in pipelines ranging from small to medium size (1/2"-3" or DN15-DN80).
Non-Rising Stem: Its compact design reduces space requirements, complemented by a visible handwheel for easy valve position indication.
Full Port: Designed for an unobstructed flow path, minimizing pressure drop and ideal for high-flow applications.
Performance Parameters
Pressure Rating: Ranges from PN10 to PN16 (150-250 psi) and can reach up to 2000 psi for specialized models.
Temperature Range: Capable of withstanding extreme temperatures from -30°C to +300°C (-22°F to +572°F), varying by material choice.
Standards: Fully compliant with ASME B16.34, API 598, and ISO 228, ensuring global compatibility.
Working Principle
Operation: The handwheel actuates the threaded stem, maneuvering the wedge-shaped gate to seamlessly open or close the valve.
Sealing Mechanism: Achieves a robust metal-to-metal or soft-seat seal when closed, entirely blocking flow. Once open, the gate retracts fully into the valve body, facilitating unrestricted flow.
Applications
Water Treatment: Perfect for potable water, wastewater, and irrigation systems, providing reliable service.
Chemical Processing: Built to resist aggressive fluids like acids and alkalis, ideal for petrochemical plant use.
Oil & Gas: Efficiently handles hydrocarbons, natural gas, and oil pipelines under moderate pressures.
HVAC & Industrial Systems: Optimal for controlling steam, hot water, and compressed air in heating and cooling networks.
Advantages
Corrosion Resistance: The stainless steel construction excels in harsh environments, significantly extending service life.
Low Maintenance: Its simplistic design reduces wear, requiring only minimal lubrication and occasional seal inspections for peak performance.
Quick Operation: The non-rising stem allows for swift on-off control with a clear indication of valve positioning.
Cost-Effective: Offers competitive pricing advantages compared to exotic alloys like Hastelloy or titanium, without compromising quality.

Installation & Maintenance
Installation: Make sure the threads are pristine and well-lubricated to facilitate a seamless installation. Exercise caution to avoid over-tightening, which can lead to unintended damage and compromise the valve's performance.
Maintenance: Ensuring optimal performance and longevity of your valve requires regular attention and care.
Regularly inspect seals and packing for wear: Consistent examination for signs of wear and tear on seals and packing is crucial for maintaining a leak-proof and efficient system.
Lubricate stem threads and bearings to reduce friction: Apply lubrication to the stem threads and bearings regularly. This practice minimizes friction, ensuring smooth operation and prolonging the lifespan of the valve.
Perform pressure tests periodically to verify integrity: Conducting routine pressure tests is essential to confirm the valve's structural integrity and ensure it meets the desired performance standards in your water treatment applications.
