Needle Valve Manufacturer in USA & Canada – SVR GLOBAL

SVR Global is a specialized Needle Valve Manufacturer in USA & Canada, delivering precision flow control for instrumentation and process lines. Our needle valves are engineered for accurate metering and tight shutoff in critical gas and liquid services, with forged bodies, non-rotating stems, and leak-tight packing for long service life.

Function & Working

A finely threaded stem drives a tapered needle into a precision seat to modulate flow. The gradual engagement provides stable, repeatable control for sampling, calibration, transmitter isolation, and high-pressure service where accuracy is essential.

Advantages

• Non-rotating stem and back-seating design to reduce seat wear
• Live-loaded PTFE or graphite packing for leak-tight performance
• Forged construction for strength and dimensional stability
• Clear service bands: 6,000 PSI, 10,000 PSI, 15,000 PSI, 20,000 PSI
• Straight or angle patterns; panel-mount and locking options
• Material traceability and optional oxygen-service cleaning

Types of Needle Valves

• Integral-Bonnet Needle Valve (compact straight/angle, 6,000 PSI)
• Union-Bonnet Needle Valve (severe service, 10,000 PSI)
• High-Pressure Cone & Thread Needle Valve (15,000–20,000 PSI)
• Miniature / Micro Needle Valve (low Cv for analytical service)
• Gauge / Instrument Manifold Needle Valve (2-, 3-, 5-valve)

Stem Tip Options

• V-tip: reliable isolation and frequent on/off
• Regulating/Metering tip: fine control for small flow changes
• Soft-seat (PCTFE): bubble-tight shutoff for clean gases
