OverviewThe J40W American Standard Globe Valve is a globe valve designed and manufactured in accordance with American national standards. By rotating the handwheel or actuator, it drives the stem and disc to perform a vertical lifting motion along the centerline of the seat, achieving reliable opening and closing of the medium in the pipeline. Its core design feature lies in strict adherence to advanced foreign standards such as ANSI B16.34 and BS1873. The valve body features an integrally cast barrel-shaped or streamlined structure with a straight-through flow path, resulting in low fluid resistance and an aesthetically pleasing appearance. The valve's closure member is a plug-type disc, with sealing surfaces featuring precision-lapped tapered or flat designs, offering low closing force, erosion resistance, and reliable sealing. The seat utilizes a replaceable structure, allowing arbitrary combination with the closure member's sealing face material based on operating conditions, effectively extending the valve's service life. The valve uses a flange connection, secured by bolts to the pipeline flange, offering a compact structure and convenient installation and maintenance. For large-diameter, high-pressure class globe valves, the stem transmission adopts a rising stem structure, equipped with rolling bearings or an impact handwheel to significantly reduce the closing operating force. Drive modes include manual, gear transmission, electric, pneumatic, and other forms, meeting the requirements of different operating conditions. This valve is widely used in pipeline systems for shutting off or passing media such as water, steam, oil products, nitric acid, acetic acid, and urea.J40W American Standard Globe Valve Product Image

OverviewThe J11W American Standard Internal Thread Globe Valve is a valve that conforms to U.S. standards (ANSI/ASME) and features an internal thread connection. It operates by driving the valve disc through the valve stem to move vertically along the centerline of the valve seat, enabling reliable opening/closing and flow regulation in pipelines. Its core design lies in the use of high-strength materials for the valve body, strictly adhering to American standards for pressure ratings and structural specifications, ensuring sealing performance and durability under demanding conditions such as high pressure and high temperature. The valve employs an internal thread connection, allowing it to be directly screwed onto external threads of American standard pipes, achieving compact, convenient installation and sealing. The valve structure is typically designed with a low-inlet, high-outlet flow path to optimize fluid control and reduce operating torque. The valve can be operated manually, converting rotational force into linear motion of the disc via the valve stem for smooth and reliable opening/closing operations. It can also be equipped with electric or pneumatic actuators to meet automation control requirements. This valve is specifically designed for water, steam, oil, and non-corrosive media in American standard pipeline systems. It is particularly suitable for applications in industries such as petroleum, chemical, power, and shipping, where strict requirements for pressure ratings, sealing performance, and installation space exist.J11W American Standard Internal Thread Globe Valve Product Diagram

OverviewThe DIN Standard Globe Valve is a pipeline control component designed in accordance with German Industrial Standards (DIN). By rotating the handwheel, it drives the stem and disc to perform a vertical lifting motion along the centerline of the seat, achieving precise opening/closing and flow regulation of the pipeline. Its core design feature lies in a rigorous standardized manufacturing system. The valve body structure is designed according to DIN standards, ensuring high interchangeability and dimensional compatibility of the product. The key sealing pair of the valve typically utilizes a tapered or flat sealing structure, and employs erosion-resistant, wear-resistant materials such as hardfaced alloy or flexible graphite, effectively ensuring sealing reliability under high temperature, high pressure, and corrosive conditions. This series of valves primarily uses flange connection or butt weld connection methods. The flange connection complies with standards such as DIN 2501/2543, securing the valve to the pipeline flange with bolts and nuts for easy disassembly and maintenance; the butt weld connection complies with standards such as DIN 3239/EN 12627, forming a permanent connection with the pipeline through welding, offering excellent pressure resistance and anti-leakage performance. The primary drive mode is manual, utilizing the threaded transmission of the handwheel and stem nut to convert rotational torque into the linear motion of the stem and disc, achieving stability and self-locking during the opening and closing process. Depending on automation control requirements, actuators such as electric, pneumatic, or worm gear drives can also be optionally equipped. DIN Standard Globe Valves are widely used in general industrial pipelines for media such as water, steam, oil products, gases, and corrosive media, particularly suitable for fields like petroleum, chemical, power, metallurgy, heating, and shipbuilding, serving as critical fluid control equipment conforming to the European standard system.DIN Standard Globe Valve Product Image

OverviewThe GOST Russian Standard Gas Stop Valve is a cast steel stop valve strictly designed in accordance with Russian GOST standards.

The closure member features a plug-type or conical disc, with sealing surfaces designed as flat or tapered surfaces. The disc moves linearly along the guiding mechanism to achieve strict shut-off of media flow direction.The valve adopts flanged connection in compliance with GOST 12815-80 standards, facilitating convenient installation and disassembly. The stem is of the rising type, converting rotational force into linear motion through thread transmission for stable opening and closing control.Available with manual or electric actuators, the valve is suitable for operating temperatures ranging from -44℃ to +434℃. It is applicable for natural gas, liquefied petroleum gas, manufactured gas, air, and weakly corrosive gas media. Widely used in oil and gas extraction, transmission pipelines, city gas systems, and chemical industries, it is particularly suitable for gas pipeline conditions with nominal pressure PN16~PN40 and nominal diameter DN50~DN300.JY4N Russian Standard Gas Stop Valve Product Drawing

OverviewThe JIS standard stop valve is a cast steel stop valve strictly designed and manufactured in accordance with Japanese Industrial Standards (JIS). It uses a handwheel or an electric device to drive the stem and disc in a vertical lifting motion along the centerline of the seat, achieving reliable opening and closing of the medium in the pipeline. The core of its design lies in the valve body, which is precision-cast using SCPH series carbon steel, SCS series stainless steel, or special alloys as specified in JIS G5151. This results in a compact structure, good rigidity, and reliable sealing. The valve seat sealing surface typically features a flat or conical design, with stainless steel or hard alloy overlay welding. Through precision grinding, a reliable metal-to-metal seal is achieved. The valve uses a flanged connection conforming to JIS B2220, fastened directly to the pipeline system flanges with bolts, offering high connection strength, reliable sealing, and convenient assembly and disassembly. The handwheel drives the stem, converting rotational force into the linear motion of the disc for smooth and reliable opening and closing control. This valve is specifically designed for pipeline systems handling steam, oil, water, and mildly corrosive media at operating temperatures ≤425°C. It is widely used in industrial pipelines requiring fluid shut-off or connection, such as in petrochemical, power generation, metallurgy, heating, and water supply & drainage industries.
