Product Summary

A crankcase ventilation system is a way for gases to escape in a controlled manner from the crankcase of an internal combustion engine. A common type of such system is a positive crankcase ventilation (PCV) system, the heart of which is a PCV valve—a variable-restriction valve that can react to changing pressure values and intermittently allow the passage of the gases to their intended destination (which nowadays is the engine's intake stream). Ventilation valve is widely used in the pipe system transporting coal gas, natural gas, venting and environment protection in building material, glass, mining, power, light industry and papermaking departments. It can change the flow and cut off gas medium in the pipe by the different control signal. It has following structure characteristic: 1) the valve has the features of lightweight, compact structure, endurance, little in the lost of flow resistance, good seal, reliable self-locking, flexible operation, definite direction, easy to maintenance and long life. 2) It can be installed at any angle. 3) It is suitable in the condition of adjusting, cutting off and self-protecting quickly. 4) The valve is used with worm gear driving device to form a complete set to realize open-close operation. 5) It is the ideal equipment of adjusting flow.
