Overview

The J11W "Su Shi" internal thread globe valve is a standard valve featuring a "Su Shi" structural design with internal thread connections. It operates by rotating the handwheel to drive the valve stem and disc, which move vertically along the centerline of the valve seat, ensuring reliable opening and closing of the pipeline. Its design centers on the integrally cast "Su Shi" flow passage structure, which reduces fluid resistance, ensures even wear on the sealing surfaces, and extends service life.

Key sealing components of the valve are made from wear-resistant and corrosion-resistant materials, combined with precisely engineered conical or planar sealing designs to guarantee excellent sealing performance under normal temperature and medium-to-low-pressure conditions. The valve employs an internal thread connection method, allowing it to be directly screwed onto the pipeline system via pipe threads, offering a compact structure and simple installation.

The valve is typically operated manually by rotating the handwheel, utilizing a threaded transmission mechanism to convert rotational force into linear motion of the valve stem and disc, achieving stable and responsive on/off control. It is widely used in pipeline systems handling water, steam, oil products, and mildly corrosive media, and is particularly suitable for applications requiring fluid shutoff or connection in instrumentation, heating, HVAC, small-scale equipment, and medium-to-low-pressure pipelines.

Features

1.Compact Structure and Convenient Connection
Featuring a classic "Su Shi" valve body design with integrally cast internal thread connections, the valve offers a simple and compact structure. It eliminates the need for additional flanges and can be directly screwed onto pipeline threads, ensuring easy installation and minimal space requirements. This makes it particularly suitable for instrument pipelines and compact equipment.

2.Excellent Sealing and Reliable Shutoff
The valve disc and seat sealing pair adopts a conical or planar sealing structure, precision-ground and paired. Combined with elastic gaskets or self-guiding mechanisms, the sealing surfaces experience uniform wear during operation, enabling tight shutoff and effectively preventing internal media leakage.

3.Low Fluid Resistance and Optimized Flow Path
The valve body incorporates a streamlined "Su Shi" flow channel design, with media flowing in a smooth "S"-shaped transition. This significantly reduces flow resistance and pressure loss while avoiding vortices and dead zones, making it suitable for systems sensitive to pressure drop.

4.Lightweight Operation and Visual Opening Indication
The valve is operated by rotating the handwheel to drive the valve stem, utilizing a threaded transmission mechanism to achieve smooth lifting and lowering of the disc. The operation requires minimal torque and ensures smooth opening and closing. The stem height directly indicates the degree of opening, facilitating manual observation and control.

5.Durability, Cost-Effectiveness, and Easy Maintenance
Key components are made of corrosion-resistant materials such as copper alloy, stainless steel, or carbon steel, ensuring robust construction and long service life. The simple overall design minimizes potential failure points, and routine maintenance or replacement of sealing components is straightforward.

6.Wide Applicability and Flexible Integration
Suitable for water, steam, oil products, and mildly corrosive media, the valve covers standard industrial pressure and temperature ranges. It can be equipped with locking devices or extended valve stems as needed to meet specific installation and operational requirements.
