  • 1. Pressure Reducing and Relieving Valves260 Instructions To use remote control relief valve in the venting circuit, see page 203. If the internal volume of the vent line is too large, chattering is likely to occur. Thus, as far as possible reduce the inside diametre and the length of the pipe. To adjust the pressure, loosen the lock nut and turn the pressure adjustment handle slowly clockwise for higher pressures and anti-clockwise for lower pressures. After adjustments, do not forget to tighten the lock nut. Pressure is limited by collars fitted. If a working pressure cannot be attained, remove some collars. One collar is equivalent to 10 MPa (1450 PSI). Connect the tank pipe not to any other line but directly to the reservoir. Pressure Reducing and Relieving Valves Pressure reducing and relieving valves are composite pressure control valves having pressure reducing and counterbalancing functions developed for hydraulic balancing circuits.
