Product Name: Gate Valve
Product Model: J41H-40C
The flanged gate valve conforms to national standards and is suitable for nominal pressure PN1.6 to 16.0 MPa, and working temperatures of -29 to 550°C in various conditions of pipelines in industries such as petroleum, chemical, pharmaceutical, fertilizer, and power generation, to cut off or connect media. The applicable media for the gate valve include: water, oil products, steam, acidic media, etc. Operating methods include: manual, gear drive, electric, and pneumatic.
Structural Features:
The design and manufacturing of the gate valve are in accordance with national standard GB12235, featuring a reasonable structure, reliable sealing, excellent performance, and an attractive appearance. The sealing surfaces of the valve disc and seat are wear-resistant, high-temperature resistant, corrosion-resistant, and have good scratch resistance, ensuring a long service life. The valve stem undergoes quenching and surface nitriding treatment, providing good corrosion and scratch resistance. Various piping flange standards and flange sealing surface types can be adopted to meet various engineering needs and user requirements. The back seal uses a threaded connection sealing seat or is welded with austenitic stainless steel, ensuring reliable sealing, and the packing can be conveniently and quickly replaced without affecting system operation.
Standards and Specifications:
Design and Manufacturing Standard: GB/T 12235-2007
Structural Length Standard: GB/T 12221-2005
Connecting Flange Standard: GB/T 9113
Pressure and Temperature Rating: GB/T 12224-2005
Testing and Inspection Standard: GB/T 13927-2008
