Selecting your Function Fitting Blocking Fittings Maintain the load following an emergency stop of a pneumatic system. Models 788-7881 - 7883-7885 7886 Soft Start Fittings Increase the pressure gradually in order to protect it from potentially damaging shock when a pneumatic system is restarted. Models 786-7861 - 787-7871 Protect Your System Non-Return Valves Allow compressed air or fluids to flow in one direction, and prevent it from flowing in the other. If the supply is accidentally shut off, the air can only escape in one direction. Models 489-4891 - 4892-4895 793-7931 - 7932-7984 7985-7992 - 7994-7995 7996 Piloted Non-Return Valves Incorporate 3 functions into one product to protect your system: piloted non-return valve, flow control regulator and manual vent. Models 7892-7894 Detect End of Cylinder Rod Stroke Pneumatic Sensor Fittings Detect the back pressure drop at the end of stroke to produce a signal (pneumatic or electronic) to allow reciprocation. Models 7818-7828 Pressure Regulators Regulate and stabilise the pressure at a maximum determined value whatever the upstream pressure. Models 7 Control and Improve the Performance of Your System Pressure Reducer Fittings Reduce the pressure consumed in one section of the machine in order to save energy. Models 7316-7318 - 7416-7471 Quick Exhaust Valves Increase the return speed of the cylinder by discharging the exhaust directly to atmosphere. Models 7899-797 - 7971 Silencers Reduce the noise levels whilst air is vented from a compressed air system. Models 67-671 - 672-673 674-675 - 676-677 Snap Fittings Allow a circuit to be isolated without fully venting the system. Models 7921-7926 - 796-7961 Working on Your System Manually-Operated Valves Allow for repeated venting by simply moving the valve sleeve or the manually-operated valve lever. Models 669-78 - 781-782 4-4

Flow Control Regulators Operation Parker Legris offers both uni-directional and bi-directional flow control regulators. The uni-directional models control the flow of air in one direction through an adjustable restrictor, while allowing full flow in the opposite direction. The bi-directional models control the flow of air in both directions. Flow Control Regulators A more precise and constant flow regulation is obtained when the regulator is fitted directly onto the cylinder.
