What is the role of the checker check valve?
Dec 05, 2018

Check valves, also known as check valves, are used in the hydraulic system of the cutting machine to prevent reverse flow of oil. Check valves are available in both straight and right angle versions. The straight-through check valve is threaded to the pipe. Right-angle check valves are available in threaded, plated and flanged versions. The pilot operated check valve is also called the lock valve and the pressure maintaining valve. It is the same as the check valve to prevent the oil from flowing in the opposite direction. 

However, when the oil flow needs to flow in the opposite direction in the hydraulic circuit, the control oil pressure can be utilized to open the check valve so that the oil flow can flow in both directions. The pilot operated check valve uses a conical spool, so the sealing performance is good. When a closed oil circuit is required, this valve can be used as a one-way locking of the oil passage to maintain the pressure. 

The hydraulic control check valve controls the leakage of oil in the form of internal leakage and external leakage. The internal venting type can be used in the oil passage with no back pressure at the reverse flow of the oil flow; otherwise, the external venting type is needed to reduce the control oil pressure.
