Product Overview
The StarkValve Stainless Steel Female Thread Needle Valve is designed for precise flow regulation and reliable shutoff in instrumentation and process-fluid systems.
Its female threaded inlet and outlet allow straightforward connection to compatible male threaded piping, adapters, gauges, and other instrumentation components. The forged stainless steel body provides a robust and compact construction for demanding industrial applications.
High-pressure configurations are available with working pressures up to 6,000 psig (414 bar). The applicable pressure rating depends on the selected connection size, valve configuration, packing, and operating temperature.
Key Features
Forged Stainless Steel Construction
The forged stainless steel body provides a robust construction for demanding instrumentation and industrial fluid-control applications.
Female Thread × Female Thread Connections
Designed for convenient integration with compatible male threaded piping, adapters, gauges, and instrumentation components.
High-Pressure Capability
High-pressure configurations are available up to 6,000 psig (414 bar), depending on valve configuration and operating temperature.
Fine Flow Adjustment
Needle-valve operation provides controlled manual adjustment for throttling and shutoff applications.
Compact Straight-Pattern Design
Suitable for instrumentation panels, process lines, test systems, and equipment installations where installation space matters.
Multiple Connection Sizes
Female NPT connections are available in multiple sizes. Other thread requirements can be reviewed according to the application.
Connection & Configuration Options
This needle valve uses a Female Thread × Female Thread connection arrangement for integration into threaded instrumentation and process systems.
Female NPT connections are available in multiple sizes to suit different installation requirements. Other thread requirements can be reviewed according to the application.
Because allowable working pressure can vary with connection size, valve configuration, packing, and operating temperature, the required service conditions should be confirmed when selecting a valve.
For accurate selection, specify:
Thread standard · Connection size · Working pressure · Operating temperature · Process media
Typical Applications May Include
StarkValve Stainless Steel Female Thread Needle Valves can be used for flow regulation and isolation in applications such as:
- Instrumentation and control lines
- Pressure measurement lines
- Sampling systems
- Hydraulic systems
- Test and calibration equipment
- Oil and gas systems
- Chemical and petrochemical processing
- Industrial gas systems
- General process-fluid systems
Final valve selection should be based on the required pressure, temperature, media compatibility, and connection conditions.
Female Thread vs. Tube-End Needle Valves
A female thread needle valve is particularly useful when the surrounding system already uses threaded interfaces. It can connect directly with compatible male threaded piping, adapters, gauges, or other instrumentation components.
For tubing systems where a direct tube connection is preferred, a needle valve with double-ferrule tube ends may provide a more direct installation without separate threaded adapters.
The appropriate connection style depends on the existing piping or tubing system and the installation requirements of the application.
Where the surrounding components provide female threaded connections, a male thread needle valve may provide a more direct connection arrangement.
How to Select the Right Configuration
Choosing a needle valve should not be based on connection size alone. The pressure-temperature capability of the complete valve configuration also needs to be considered.
1. Thread Standard
Specify the required thread standard, such as Female NPT or another required configuration.
2. Connection Size
Provide the mating thread size required by the piping or instrumentation system.
3. Working Pressure
Provide the normal operating pressure and maximum design pressure where applicable.
4. Operating Temperature
Temperature affects packing selection and the allowable working pressure of the valve.
5. Process Media
Specify whether the valve will handle gas, chemicals, water, oil, or another process fluid.
6. Material and Documentation Requirements
Provide any specific material grade, documentation, or project requirements.
StarkValve can then confirm the appropriate configuration and applicable pressure-temperature rating before quotation and production.
Frequently Asked Questions
What is a female thread needle valve used for?
A female thread needle valve is used for controlled flow regulation and shutoff where the valve connects to compatible male threaded piping, gauges, or instrumentation components. Typical applications include instrumentation, sampling, hydraulic, test, and process-control systems.
What is the maximum working pressure?
High-pressure configurations are available up to 6,000 psig (414 bar). The actual rating depends on valve configuration, connection size, packing, and operating temperature.
What thread connections are available?
Female NPT connections are available in multiple sizes. Other thread requirements can be reviewed according to application requirements. The required thread standard should be specified when requesting a quotation.
What connection sizes are available?
Multiple connection sizes are available. Because available size and pressure combinations can vary by configuration, provide the required connection size and operating conditions for confirmation.
Can the valve be used for both liquids and gases?
Suitable configurations can be used for liquid or gas service when the valve materials, packing, pressure rating, and temperature capability are compatible with the process media.
How do I select the correct valve configuration?
Provide the required thread standard, connection size, working pressure, operating temperature, process media, and any material or documentation requirements. StarkValve can then confirm the appropriate valve configuration and applicable pressure-temperature rating.
