Structure and working principle 1. Shandong floating valve seat, two-way open and close, reliable seal, flexible. 2. Each guide bar gate to give precise guidance, while sealing surfaces are spray carbide, resistance to erosion. 3. Body carrying capacity, channel for straight-through, when fully open, with the gate and diversion hole straight through a similar phase Z43H steel plate valve supplier, flow resistance is small. Stem composite packing, multi-sealed, making reliable sealing, small friction. Use, maintenance, service and Notes 1. Valve factory have made and seal strength testing, the use of all connections should be maintained at the initial state. 2. This series marked the opening and closing the valve handwheel rotation flag gate, opening and closing out with a highly leveraged upper scale for adjustment instructions. 3. The valve and pipe welding, the valve should be open, appropriate physical protection of the neck with a damp minimize high temperature thermal conductivity, to prevent damage to the gasket. 4. Close the valve prohibited the use of afterburner lever gate close to the hand wheel should be turning 1/2 turn at the top of the shutter in a floating state. 1. Structure and works with floating seat, two-way open and close, reliable seal, flexible. 2. Each guide bar gate to give precise guidance, while sealing surfaces are spray carbide, resistance to erosion. 3. Body carrying capacity, channel for straight-through, when fully open, with the gate and diversion hole straight through a similar phase steel plate gate Z43H quotes, flow resistance is small. Stem composite packing, multi-sealed, making reliable sealing, small friction. Weifang valves, valve type Everbright (certified), gate valves Everbright Limited provided by Shandong. Valve Co., Ltd.
