9/16" HP Female x Female Needle Valve – 30,000 PSI Autoclave-Style Flow Control

The 9/16" High-Pressure (HP) Female x Female (FXF) Needle Valve is a premium flow control component engineered for precise fluid throttling, regulation, and absolute isolation in ultra-high-pressure instrumentation and fluid control systems. Rated for a Maximum Allowable Working Pressure (MAWP) of 30,000 PSI (30K), this Autoclave-compatible valve is an industry standard for chemical injection skids, high-pressure test benches, and deepwater control panels where absolute reliability is mandatory.

Manufactured from heavy-duty, cold-worked 316 stainless steel, the valve body delivers exceptional structural integrity and superior resistance to harsh chemicals, corrosive media, and severe offshore environments. It features 9/16" High Pressure (HP) female ports on both ends, utilizing the proven coned and threaded technology to ensure a blowout-proof, bubble-tight metal-to-metal seal under extreme pressures and vibration.

A critical design feature is its non-rotating stem tip. As the valve is closed, the stem tip moves linearly into the seat without rotating, preventing the galling, scoring, and excessive wear typically seen in standard rotating stems. Combined with robust high-pressure packing (typically PTFE/Glass or engineered polymers) located below the stem threads, this valve guarantees long-lasting, leak-free performance and smooth operation even at its maximum 30,000 PSI threshold.

Features & Benefits

• 30,000 PSI MAWP Rating: Safely contains and regulates ultra-high fluid and gas pressures for the most demanding industrial and oilfield applications.

• 9/16" HP FXF Connections: Standard Autoclave-style coned and threaded female ports ensure a highly reliable metal-to-metal seal with 9/16" high-pressure tubing.

• Non-Rotating Stem Tip: Prevents galling and seat damage during closure, drastically extending the service life of the valve and maintaining a perfect seal.

• Cold-Worked 316 SS Construction: Delivers exceptional tensile strength and maximum resistance to internal chemical attack and external environmental corrosion.

• Below-Thread Packing: The stem packing is located below the actuating threads, preventing process fluids from washing away thread lubricants or causing thread corrosion.

• Precision Flow Control: Engineered for smooth, micro-metering and positive shut-off without system pressure drop spikes.

Specifications & Technical Details

Applications

This 9/16" 30K HP needle valve is essential for precise manual flow control and absolute shut-off in ultra-high-pressure circuits. Typical applications include isolating pressure gauges and transducers on hydrostatic test benches, regulating flow rates on offshore chemical injection systems, and managing fluid distribution within blowout preventer (BOP) hydraulic power units (HPUs).

Quality Assurance

Each needle valve undergoes rigorous quality control and assembly protocols. The coned seating surfaces are precision-machined for a flawless metal-to-metal seal. Every unit is subjected to high-pressure hydrostatic testing to verify seat integrity, packing containment, and body strength. All 316 SS materials are fully traceable, ensuring fail-safe performance at 30,000 PSI.
