Stainless Steel American Standard Globe Valves

Stainless Steel American Standard Globe Valves are critical shut-off and regulating devices in industrial automated piping systems.They control flow and provide precise throttling by moving the disc via the valve stem (manual or electric), ensuring stable pipeline operation.

Designed and manufactured to strict US standards including API and ASME, the valves feature high-corrosion-resistant austenitic stainless steel and ANSI flanged or threaded connections.They deliver excellent sealing, stable regulation and strong corrosion resistance for high-temperature, high-pressure and corrosive environments.

Widely used in oil, chemical, LNG, power, pharmaceutical and other high-end industries, these valves can be customized in structure, material and actuation to meet diverse application demands, providing reliable protection for safe and efficient industrial production.

Selection Points

Proper selection directly determines valve compatibility and service life. Selection must be based on operating conditions, medium characteristics and American standards to ensure ideal performance.

Pressure & Temperature Matching

Verify working pressure and medium temperature in strict accordance with ANSI/ASME B16.34.Do not use the valve beyond rated conditions to avoid damage, leakage or safety hazards.

Material Selection

Light corrosion: 304 stainless steel

Strong corrosion (chlorine, acid, etc.): 316L stainless steel for improved corrosion resistance and longer life.

Seal & Flange Selection

High-pressure, high-temperature or particle-laden service: metal hard seal + RJ (Ring Joint) flange for maximum sealing reliability.

General service: RF (Raised Face) flange for practicality and economy.

Actuation Selection

Remote control or high-frequency operation: electric or pneumatic actuator with NEMA explosion-proof and protection rating.

Small-medium bore, low-frequency operation: manual handwheel to reduce cost.

Sealing Class Matching

Toxic, flammable or explosive media: soft seal (API 598 Class VI) for zero leakage.

General service: metal seal (API 598 Class IV) for balanced sealing and durability.

Operation and Maintenance Notes

Correct operation and regular maintenance extend service life and reduce operating costs.

Pre-Installation Inspection

Verify valve model, pressure class and material match actual service conditions.Clean all dirt, oil and impurities from flange sealing surfaces.

Standard Installation

Install according to the flow direction marked on the valve body: low inlet, high outlet.Reverse installation will increase operating torque, cause seal failure or damage components.

Electric Valve Commissioning

Check wiring before testing. Run no-load trials to confirm correct rotation direction and limit settings before putting into service.

Regular Maintenance

Periodically inspect packing gland sealing.Minor leakage can be corrected by evenly tightening the packing follower.Replace packing promptly if leakage is severe.

Restart After Long-Term Storage

Before startup, turn the stem manually (switch electric valves to manual mode).Ensure no binding or abnormal noise before resuming normal operation.
