Product Features & Advantages
Space-Saving Design & Easy Installation: The compact threaded-body configuration requires minimal installation space and simplifies integration into existing piping systems without specialized tools or welding equipment. The non-rising stem design eliminates the need for overhead clearance, making it perfect for confined spaces.
Reliable Shut-Off Performance: The solid wedge disc ensures bubble-tight sealing when fully closed, while the precision-machined seats minimize turbulence and pressure drop across the valve. This design provides positive isolation for system maintenance and process control.
Durable Construction & Smooth Operation: Manufactured from corrosion-resistant materials with a screw-in bonnet and reinforced packing arrangement, the valve offers long service life with minimal maintenance requirements. The inside-screw mechanism protects threaded components from environmental contaminants.
Versatile Bonnet Configurations: Available in screw-in, bolted, or welded bonnet options to match specific pressure requirements and service conditions. This modularity allows for appropriate selection from standard 200 PSI WOG ratings to higher pressure applications.
Broad Compatibility & Cost Efficiency: Suitable for water, oil, gas, and other non-aggressive media, the valve provides an economical solution for applications where frequent operation is not required while maintaining excellent performance in moderate duty cycles.

FAQ
Q: What applications are most suitable for threaded gate valves?
A: Threaded gate valves are ideal for small to medium-sized piping systems in HVAC, plumbing, instrumentation lines, and general industrial services where space constraints, moderate pressure conditions (up to 200 PSI WOG), and infrequent operation make them a cost-effective and practical choice.
Q: How does the non-rising stem design benefit installation and operation?
A: The non-rising stem design maintains a constant vertical dimension during operation, eliminating the need for overhead clearance. This feature makes these valves particularly valuable in confined spaces, while also protecting the stem threads from external contamination and damage.
Q: What pressure ratings and materials are available?
A: Standard threaded gate valves are typically rated for 200 PSI WOG at temperatures up to 350°F (177°C), with common materials including 316 stainless steel for corrosion resistance. Bronze versions are also available for less demanding applications, with higher pressure ratings possible through bolted or welded bonnet configurations.
Q: How does the solid wedge disc ensure reliable sealing?
A: The solid wedge disc provides two-point contact with the valve seats, creating a mechanical advantage that ensures tight shut-off even after prolonged periods in the open position. This design minimizes leakage potential and provides dependable isolation for system maintenance and process control.
