Description

Functional Features:
The DYC-JQ type electromagnetic vacuum differential pressure valve is a safety valve for mechanical vacuum pumps. It is installed at the inlet of the mechanical vacuum pump and opens or closes synchronously with the pump. When the pump stops working or the power supply is suddenly interrupted, the valve uses the atmospheric pressure to automatically close the valve plate, maintaining the vacuum of the vacuum series and allowing the atmosphere to be filled into the pump chamber, thereby preventing the reverse flow of pump oil and contamination of the vacuum system. It is suitable for pure air media and non-corrosive gases.
