water seal gate valve is suitable for the rated pressure 100 mpa, the working temperature of 425 C, water, steam, oil, and without the working medium of corrosive gas pipeline as an opening and closing device, especially suitable for thermal power plant steam turbine vacuum cooling system. Water seal gate valves, pressure for PN16 - PN160，150LB- 900 lb steel globe valve applies to 1. 6 - 25 mpa / 2。 0 - 15. The pressure of 0 mpa. Temperature - at work 29 ~ + 550 ~ C of petroleum, chemical, pharmaceutical, chemical fertilizer, power industries of the pipeline, suitable for medium such as water, oil, steam, acid medium, material is usually cast steel WCB, stainless steel CF8 ( M） 恶( M） , forged steel A105, F304 ( L） 。 ) F316L wait a 1, characteristics and purposes. S/Z series adopts double gate two-way elastic seal, easy, quick and reliable sealing. 2. The product structure is simple, reasonable compact structure, convenient maintenance, long service life. 3. As pipe opening and closing device, must be fully open or close and cannot be used to adjust flow. Four. A way to connect the valve with flange and welding. Driving mode for manual, electric, the structure is complex. According to the sealing surface configuration, gate valve can be divided into wedge gate valve and parallel gate valve. Wedge gate can also be divided into single gate, double gate and elastic gate; Parallel to the valve can be divided into single gate and double gate. According to the threads of the valve stem position, can be divided into the Ming bar type and dark bar type two kinds. Design and manufacture of standard design and manufacture: GB12234 flange dimensions: GB9113 JB7490 pressure, temperature, JB/T74 GB9131 structure length: GB/T12221 inspection and test: JB/T9092 GB13927
