Single suction valve

Single suction valve is one of the important devices for pipeline storage equipment of various gases and liquids that are prone to thermal expansion, contraction or volatility during storage. It is a safe and energy-saving product that maintains the pressure balance of the storage tank, ensures that the storage tank or reaction kettle is damaged when negative pressure is generated when the pressure decreases, and reduces the volatilization and loss of the medium inside the tank. When the pressure inside the storage tank or reactor decreases to the set value, the suction valve disc automatically opens to suck in gas from the atmosphere, ensuring the safety performance of the storage tank while exerting the suction function. The valve discs of the single suction valves, flame retardant single suction valves, and explosion-proof single suction valves produced by Shanghai Meiyan Yi Pump Valve are made of polytetrafluoroethylene material, which has the advantages of low temperature resistance, antifreeze, etc. The valves are equipped with electrostatic output devices to maintain equal potential with the tank body at all times. After testing and inspection, all technical indicators fully comply with the standards of various national ministries and commissions.
