Forged Gate Valve in stock gate valve sw Full-port gate valve(fullway gate valve or full bore gate valve) is used in situations where large flow or pipelines need to pass through a sweeper. It is mainly used in general occasions such as water, gas, oil products, etc. Material: CF3M CF3 CF8M CF8 CF8C WCB Size Range: DN50-DN1000 2鈥?40鈥?/p Pressure Rating: 1.0Mpa-10MPa 150LB-600LB Temperature Range: 20掳C~425掳C Advantage: 1. The use of equal-diameter straight-through structure with runner greatly reduces the loss of flow resistance coefficient and energy, and significantly improves the service life and performance of the valve. 2. The valve chamber adopts pressure self-tightening sealing structure, which has good sealing performance. 3. The sealing surface of gate and seat is made of cemented carbide surfacing, which has good wear resistance, high temperature resistance, corrosion resistance and abrasion resistance. 4. The surface of the valve stem has good corrosion resistance and abrasion resistance after corrosion-resistant nitriding treatment. 5. The structure of hoist can be designed into single board, double board and parallel double board according to user's requirements. Inspection after installation of gate valve: 1.After the gate valve is installed, check that the installation accuracy meets the installation requirements and that all fasteners are firmly connected; check and fill the grease in the hoist; 2.Under the condition of no water, carry out the opening and closing test of the gate valve, to achieve flexible operation, in place action, stable screw rotation, no clamping, sudden jump and abnormal noise of the door plate; 3.Under the designed water level, the gate valve can be opened and closed freely without sudden jump, and the limit device shall be sensitive, accurate and reliable; 4.Assist the supplier to conduct on-site leakage test according to relevant regulations. Under the condition of maximum design water level, the leakage of gate valve meets the regulations.Forged Gate Valve in stock website:http://www.gangyevalve.com/gate-valve/forged-gate-valve/
