It can be divided into pneumatic(air) control valve, electric control valve and hydraulic control valve according to its driven power. PERFECT’s single seat control valve is straight through with pneumatic and electric actuator for cooling water, hot water, steam, gases, and thermal oil. The metal single/double seat and top guide structure design offer compact structure and S-type streamline body channel, can be used to control a variety of pressure and temperature fluid.

As a leading valve manufacturer and supplier, PERFECT produce a series of pneumatic control valve and electric control valve for sale to meet the most severe requirements of challenging temperature media. Our pneumatic control valve is available from ANSI 1500 class up to 2500 pressure and We can also accept the OEM design, so whether you need special valves or have a large order to place, we can provide you with the customized service for you.
