Beijing Jiujiu Yuda Electromechanical Technology Co., Ltd.

JOJOVAC is a high vacuum valve manufacturer. The high vacuum pneumatic gate valves are often used in applications to isolate gas flow in the high vacuum and ultra-high vacuum system. The compressed air pushes the cylinder as the power to drive the valve plate to open and close.
The valve body is made of stainless steel and undergoes a rigorous polishing process, ensuring high structural rigidity, smooth operation, and an aesthetically pleasing appearance. The shaft seal is a stainless steel bellows seal, providing a long service life and good sealing performance. It is suitable for working conditions where the medium is air or non-corrosive gases.
