Features
GQC series safety valves for rotary vacuum pump are electromagnetic power as a driving force, when power connected, the valve was closed so that a vacuum system and atmospheric are isolation, cut off power, in the opening of valves, atmosphere is subsequently made into the vacuum system. Valves for air and medium are applicable to the work of non-corrosive gases.

Features
GDC-J Series safety valves for rotary vacuum pump take electromagnetic power as a driving force to enable valves open or closed. Apply vacuum system, or used to cut through air currents purposes. Working medium is applicable to non-corrosive gases and air. Valves closed, sealed surface side panels allow bear pressure valves, adjacent to the vacuum sealed role to play in this state, connected electrical power boxes, valves should be opened to normal.

Features Solenoid Valve
GDC-Q5 type Series safety valves for rotary vacuum pump is to bring in high-vacuum systems, when valves supply, it will make the P,A tube road access, while closed inflatable mouth low extremity, power-line, cutting off charge, and maintain the vacuum system for, and through F-to- A charge.
GDC-5 type Solenoid high vacuum baffle plate valves are connected in the high-vacuum tube road to access or closed vacuum system air stream.
GDC-Q5 type&GDC-5 types' working medium are applicable to non-corrosive gases and air.

Features Solenoid Valve
Safety valves for rotary vacuum pump are installed in the mechanical vacuum pump into the mouth of dedicated gas valves, and with the same power to pump, pumps’ stop and open will directly control valves' open and close. When the pumps stop working or sudden power interruption, using atmospheric pressure valves for valve panels will be automatically ended vacuum system closed, and the atmosphere through the inflatable valves to pump into the mouth of the valve cover, thus avoiding pumping uphill pollution vacuum system. Valves for air and medium are applicable to the work of non-corrosive gases.

 Solenoid Valve
Features
DDC －JQ Series safety valves for rotary vacuum pump is the special valves installed in mechanical vacuum pumps, which pumps and it are at the same power, the pumps and stop the opening of the direct control valves open and closed. When the pumps stop working or sudden power interruption, the automatic valves to be closed vacuum system, and the atmosphere through the inflatable valves made into the mouth of the valves to the pump, thereby avoiding pumping current pollution vacuum system. Working medium is applicable to non-corrosive gases and air.
