OverviewThe WJ45Y American standard bellows globe valve is a special valve designed with a metal bellows dynamic seal. The valve disc is driven vertically along the centerline of the valve seat by the valve stem to achieve reliable opening and closing of the pipeline and flow regulation. The core of its design is to use fully enclosed metal bellows components instead of traditional packing boxes, completely isolating the valve stem from the process medium. The elastic deformation of the bellows compensates for the valve stem stroke, thereby completely eliminating medium leakage at the valve stem. The key sealing components of the valve are made of high-quality alloy materials that are corrosion-resistant and erosion resistant. The corrugated pipe is formed by multi-layer lamination process, which has extremely high fatigue life and pressure bearing capacity, ensuring zero leakage sealing and long-term reliable operation under harsh working conditions such as high temperature, high pressure, toxic and harmful, flammable and explosive. The valve strictly follows the American standard specifications such as ASME B16.34, and is connected using RF or RJ flanges. It is firmly fixed to the pipeline flange with bolts. Valves can be driven by manual devices or matching electric/pneumatic devices to convert input force into linear motion of the valve disc, achieving smooth and reliable opening, closing, and regulating control. This valve is designed specifically for process pipeline systems in industries such as petroleum, chemical, pharmaceutical, and energy that require extremely high leak control. It is particularly suitable for steam, toxic gases, volatile liquids, vacuum systems, and other hazardous or environmentally sensitive medium conditions that require absolute no leakage.WJ45Y American standard corrugated pipe globe valve product diagram

OverviewThe U41S Plunger Stop Valve is a special structure stop valve that achieves reliable sealing through the interference fit between the plunger and the sealing ring. Driven by the valve stem, the plunger performs vertical lifting motion within the sealing ring to complete the opening/closing and flow regulation of the pipeline medium. The core of its design lies in replacing the traditional disc with a plunger. The interference fit design between the plunger and the upper and lower elastic sealing rings, combined with the pre-tightening force adjustment of the middle flange bolts, causes the side force generated by the compression of the sealing rings to act on the outer cylindrical surface of the plunger and the bore surface of the valve body. This forms a reliable radial sealing pair, thereby achieving excellent zero-leakage sealing performance. The key components of the valve feature a stainless steel plunger and high-performance non-metallic sealing rings (such as flexible graphite, PTFE composite materials, etc.). The sealing rings possess characteristics of strong resilience, high wear resistance, and high-temperature resistance, maintaining elasticity and sealing performance during long-term use. The valve typically adopts a flanged connection, securely fixed to the pipeline flanges with bolts, offering convenient installation and reliable sealing. The opening and closing of the valve are achieved by turning the handwheel or a matching electric actuator to drive the valve stem, converting rotary motion into the vertical lifting motion of the plunger for smooth and reliable control.
