Synthetic rubber oil resistance, temperature resistance, corrosion resistance and other comprehensive performance better than natural rubber. General synthetic rubber operating temperature t ≤ 150 ℃, natural rubber t ≤ 60 ℃, rubber for nominal pressure PN ≤ 1MPa globe valve, gate valve, diaphragm va

Large diameter valvesButterfly valve, gate valve and globe valve, whose role is to balance the difference in pressure between the import and export of sewage treatment equipment to reduce the opening force. When opening, the bypass valve should be opened first, and then open the larger valve after t
