The Cast Steel Bellow Seal Globe Valve is a heavy-duty industrial valve engineered for reliable flow regulation and zero stem leakage in demanding service conditions. Constructed from high-quality cast carbon steel (such as ASTM A216 Gr. WCB), this valve offers excellent mechanical strength, corrosion resistance, and thermal durability. It features a flexible metallic bellow seal welded to both the stem and bonnet, forming a hermetic barrier that prevents fugitive emissions and ensures leak-free performance over extended cycles. The globe-style disc design allows for precise throttling and positive shut-off, making it ideal for steam, gas, oil, and chemical service. The valve includes a bolted bonnet, renewable seat rings, and is available with flanged or butt-welded end connections. Commonly used in power plants, refineries, and chemical industries, this valve is suitable for high-pressure, high-temperature pipelines where safety and operational integrity are critical

Manufactured from forged or cast carbon steel, alloy steel, or stainless steel, the Y-Type Bellow Seal Globe Valve features a robust Y-pattern body that reduces turbulence and pressure loss compared to conventional globe valves. The metallic multi-ply bellows is welded to the stem and bonnet, providing a hermetic seal that eliminates emissions and ensures zero stem leakage. This makes it particularly suitable for handling hazardous or toxic media. The valve is available in sizes ranging from " to 12" (DN15DN300) and pressure classes from Class 150 to Class 1500 (PN16 to PN250). It includes bolted bonnet construction, back seat arrangement, rising stem, and an optional handwheel or gear operation. The valve conforms to international standards such as API 602, ASME B16.34, DIN, and BS EN. Optional end connections include flanged, socket weld, or butt weld. This valve is engineered for long-term durability, low maintenance, and safe operation under extreme temperature and pressure conditions.

The Cast Iron Bellow Seal Valve is a durable and cost-effective solution designed for low to medium pressure applications requiring leak-tight stem sealing. Constructed from high-quality cast iron (typically conforming to ASTM A126 or equivalent), this valve is equipped with a flexible metallic bellow seal that eliminates gland packing and ensures zero stem leakage, making it ideal for handling steam, hot water, condensate, and non-corrosive fluids. Its robust body structure provides good mechanical strength and vibration resistance, while the bellow seal design prevents fugitive emissions and extends maintenance intervals. Available in gate or globe configurations, the valve features flanged ends for easy integration into pipeline systems, along with a bolted bonnet and rising stem for reliable shut-off and control. Commonly used in HVAC systems, heating plants, utility services, and industrial process lines, this valve offers a balance of performance, economy, and environmental safety.

The Stainless Steel High Pressure Bellow Seal Globe Valve is a precision-engineered valve designed for leak-proof performance in corrosive and high-pressure applications. Constructed from high-grade stainless steel such as ASTM A182 F304, F316, or F316L, it offers exceptional resistance to corrosion, oxidation, and thermal stress. The valve features an integrated metallic bellow seal that ensures a hermetic stem seal, effectively eliminating fugitive emissions and external leakage—making it ideal for critical services involving toxic, flammable, or high-purity media. Its globe-style design enables precise throttling and flow control, while the robust construction supports pressure ratings up to Class 800, 1500, or 2500. Suitable for use in chemical plants, power generation, petrochemical, and steam service environments, this valve includes a bolted bonnet, renewable seat rings, and options for socket weld, butt weld, or flanged end connections. It ensures long service life with minimal maintenance, even under extreme operating conditions

Manufactured from high-quality forged carbon steel or stainless steel, the bellow seal globe valve features a multi-layered stainless steel bellows welded to the stem and bonnet to create a hermetically sealed barrier. This prevents any fluid leakage through the stem, ensuring zero emissions and fugitive emission compliance. The valve body is designed in a T-pattern or Y-pattern globe configuration, suitable for throttling and regulating flow. Standard pressure ratings range from Class 150 to Class 800, and sizes typically range from " to 2" (DN15 to DN50). The valve is equipped with a back seat arrangement, bolted bonnet, rising stem, and optionally a handwheel or gear operator. It meets design and testing standards such as API 602, BS 5352, and ASME B16.34. Ideal for applications involving high temperatures, thermal oil, steam, or toxic media, the bellow seal design significantly extends service life and minimizes operational risks.

The Forged Bellow Seal Globe Valve is a robust, high-integrity valve engineered for critical fluid control in high-pressure and high-temperature environments. Manufactured from premium forged materials such as carbon steel (A105), alloy steel (F11/F22), or stainless steel (F304/F316), this valve ensures superior mechanical strength, dimensional stability, and corrosion resistance. Its integrated metallic bellow provides a hermetic seal around the stem, eliminating the risk of fugitive emissions and external leakage, making it ideal for hazardous or toxic service conditions. The globe valve design ensures precise throttling and smooth flow regulation, while the compact forged body supports space-efficient installation. Commonly used in steam, thermal oil, petrochemical, and power generation systems, the valve features a bolted bonnet, optional stellite trim, and a long service life with minimal maintenance. Available in pressure classes up to 2500 and various end connections including socket weld, butt weld, and threaded types.
