Overview

J13W needle type internal thread globe valve is a small-sized precision globe valve connected by metric fine thread internal thread. It drives the conical needle shaped valve disc to move vertically along the center line of the valve seat through the valve stem, achieving reliable opening and closing of instrument pipelines and micro flow regulation. The core of its design lies in a compact overall forged valve body structure, high-precision guiding threads, and a conical sealing pair that contacts the valve disc and seat. It adopts a metal hard sealing structure directly processed from the valve body to ensure a tight shut-off effect under high pressure conditions. High quality stainless steel materials are selected for key components of valves based on pressure temperature levels and medium characteristics to ensure long-term sealing reliability in corrosive media. The valve adopts metric fine tooth internal thread connection (such as M20 × 1.5), which is directly connected to the instrument pipeline through threads, with a compact structure and reliable sealing. The valve drives the precision threaded stem through the top handwheel, converting the rotational force into linear micro movements of the valve disc, achieving precise opening and closing control and flow regulation. This valve is designed specifically for instruments, sampling systems, and high-pressure pipelines, and is particularly suitable for precise control and reliable shut-off of high-pressure and low flow media such as steam, oil, and gas.

1. Precise adjustment and reliable sealing: The needle shaped valve disc and valve seat structure with conical line contact are adopted, and the precise micro lifting of the valve disc is achieved through fine thread, which can realize precise flow regulation and tight cutting under high pressure conditions. The metal hard sealing structure processed on the valve body ensures reliable shut-off and long-term sealing stability under high pressure and low flow conditions.

2. Compact structure and high pressure applicability: The valve adopts an integral forged valve body, which has a compact structure, small volume, and excellent high pressure resistance performance. Its integrated design minimizes potential leakage points, making it particularly suitable for instrument measurement, sampling, and high-pressure piping systems with limited space and high requirements for pipeline system integrity.

3. Excellent materials and corrosion resistance: Key components are usually made of high-quality stainless steel (such as 304, 316) and other materials, which have good corrosion resistance and can be safely applied to steam, oil, gas and general corrosive media, meeting the control needs of various industrial fluids in high-pressure environments.

4. Easy to operate and precise control: The high-precision fine tooth valve stem thread is driven by the top handwheel, ensuring smooth transmission and even torque, and enabling precise adjustment and self-locking of valve disc opening. The operation process is intuitive, the control is precise, and it is convenient for micro flow regulation and stable interception.

5. Reliable connection and easy installation: Using metric fine thread internal connections (such as M20 × 1.5, M22 × 1.5, etc.), it has good compatibility with instrument pipeline interfaces, easy and reliable connection, excellent sealing, effectively saves installation space, and is particularly suitable for integration in complex instrument pipeline systems.

6. Standardized design and quality assurance: Product design, manufacturing, and testing follow general mechanical standards and industry specifications, with good consistency and interchangeability in key dimensions and performance. A strict quality control system ensures that each valve undergoes pressure testing and sealing inspection before leaving the factory, ensuring reliable quality and stable performance.
