Product Overview
The StarkValve Stainless Steel Male Thread Needle Valve is designed for precise flow regulation and reliable shutoff in high-pressure instrumentation and process-fluid systems.
Featuring male threaded inlet and outlet connections, a one-piece forged 316 stainless steel body, and a two-stem design, the valve provides a compact configuration for integration with compatible female threaded piping, manifolds, adapters, and instrumentation components.
High-pressure configurations are available with working pressures up to 10,000 psig (689 bar). The applicable pressure rating depends on the selected valve configuration, connection size, packing, and operating temperature.
Key Features
Up to 10,000 psig (689 bar)
Selected stainless steel configurations are available for high-pressure service up to 10,000 psig (689 bar), subject to valve configuration and operating temperature.
One-Piece Forged Body
The one-piece forged 316 stainless steel body provides a robust pressure-containing structure for demanding instrumentation and process applications.
Male Thread × Male Thread Connections
Designed for direct integration with compatible female-threaded piping, manifolds, adapters, and instrumentation components.
Two-Stem Design
The upper and lower stem arrangement allows the lower stem to move linearly during valve operation, reducing rotational movement at the seat and tip interface.
Fine Flow Regulation
Needle-valve operation provides controlled manual adjustment for throttling and shutoff applications.
Packing Options Depend on Service Conditions
Packing selection should be matched to the required operating temperature, pressure, and process media.
Panel Mounting Available
Panel-mount configurations are available where required for instrumentation panels and equipment installations.
Connection & Configuration Options
This needle valve uses a Male Thread × Male Thread connection arrangement for integration into threaded instrumentation and process systems.
Male NPT connections are available in multiple sizes. 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 · Packing requirements
Two-Stem Design for High-Pressure Service
The two-stem arrangement separates the threaded upper-stem function from the lower stem that controls the valve opening.
During operation, the lower stem moves linearly rather than rotating continuously against the seat. This helps reduce rotational contact at the seat and stem-tip interface and can reduce packing friction during valve operation.
The design is particularly suited to high-pressure needle-valve configurations where controlled manual adjustment and reliable shutoff are required.
Pressure and Temperature Considerations
Selected stainless steel configurations are available with maximum working pressures up to 10,000 psig (689 bar).
The allowable working pressure depends on the complete valve configuration and generally decreases as operating temperature increases. Connection size, packing selection, and other configuration details must therefore be considered together when selecting the valve.
Different packing materials can support different service-temperature ranges. Packing should be selected according to the required pressure, temperature, and process media rather than by temperature alone.
For applications approaching the maximum pressure or temperature limits, provide the complete operating conditions for configuration confirmation before ordering.
Typical Applications May Include
StarkValve Stainless Steel Male Thread Needle Valves can be used for flow regulation and isolation in applications such as:
- High-pressure instrumentation lines
- Hydraulic systems
- Pressure measurement systems
- Test and calibration equipment
- Sampling systems
- Oil and gas systems
- Chemical and petrochemical processing
- Industrial gas systems
- General high-pressure process-fluid systems
Final valve selection should be based on the required pressure, temperature, media compatibility, connection conditions, and packing requirements.
Male Thread vs. Female Thread Needle Valves
Male thread needle valves are typically selected where the surrounding system provides compatible female-threaded connection points.
Female thread needle valves, by comparison, connect directly with compatible male-threaded piping, manifolds, adapters, gauges, or other instrumentation components.
The appropriate connection arrangement should therefore be selected according to the existing system interface rather than pressure rating alone. Male and female threaded needle valves can be available in different pressure classes and internal constructions.
How to Select the Right Configuration
Selecting a high-pressure needle valve requires more than choosing the thread size.
1. Thread Standard
Specify the required thread standard, such as Male NPT or another required configuration.
2. Connection Size
Provide the mating thread size required by the piping or instrumentation system.
3. Working Pressure
Provide both normal operating pressure and maximum design pressure where applicable.
4. Operating Temperature
Operating temperature affects packing selection and the allowable working pressure of the valve.
5. Process Media
Specify the liquid or gas being controlled so material and packing compatibility can be evaluated.
6. Packing Requirements
Packing selection depends on the required pressure, temperature, and process conditions.
7. Material and Documentation Requirements
Provide any required material grade, documentation, traceability, testing, or other project-specific requirements.
StarkValve can then confirm the appropriate valve configuration and applicable pressure-temperature rating before quotation and production.
Frequently Asked Questions
What is a male thread needle valve used for?
A male thread needle valve provides controlled flow regulation and shutoff in systems with compatible female-threaded interfaces. It is commonly used in instrumentation, hydraulic, pressure-measurement, testing, sampling, and process-fluid systems.
What is the maximum working pressure?
Selected stainless steel high-pressure configurations are available with maximum working pressures up to 10,000 psig (689 bar). The actual allowable pressure depends on valve configuration, connection size, packing, and operating temperature.
What type of thread does this valve use?
The standard threaded configuration uses Male NPT × Male NPT connections. Other thread requirements can be reviewed according to the application.
What is the advantage of the two-stem design?
The two-stem arrangement allows the lower stem to move linearly during valve operation rather than continuously rotating against the seat. This reduces rotational contact at the seat and stem-tip interface.
What body material is used?
The high-pressure configuration described on this page uses a one-piece forged 316 stainless steel body.
What packing options are available?
Packing selection depends on the required operating pressure, temperature, and process media. Provide the operating conditions so the appropriate packing configuration can be confirmed.
What connection sizes are available?
Multiple Male NPT connection sizes are available. Because available size and pressure combinations can vary by configuration, provide the required connection size and operating conditions for confirmation.
How do I select the correct valve?
Provide the required thread standard, connection size, working pressure, operating temperature, process media, packing requirements, and any material or documentation requirements. StarkValve can then confirm the appropriate configuration.
