5 Selecting Your Function Fitting Blocking Fittings Maintain the load following an emergency stop of a pneumatic system. Models Soft Start Fittings Increase the pressure gradually in order to protect it from potentially damaging shock when a pneumatic system is restarted. Models Protect Your System Non-Return Valves llow compressed air 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 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 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 Pressure Regulators Regulate and stabilise the pressure at a maximum determined value whatever the upstream pressure. Models 73 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 Quick Exhaust Valves Increase the return speed of the cylinder by discharging the exhaust directly to atmosphere. Models Silencers Reduce the noise levels whilst air is vented from a compressed air system. Models Snap Fittings llow a circuit to be isolated without fully venting the system. Models Working on Your System Manually-Operated Valves llow for repeated venting by simply moving the valve sleeve or the manually-operated valve lever. Models

7 Selecting Your Flow Control Regulator The comprehensive range of Parker Legris flow control regulators provides a solution for all flow regulation functions in a pneumatic system. Select the model suited to your application according to: 5 Key Requirements 1. Condition of Use Standard applications Severe applications Technical polymer models Metal models 2. Connection Options On cylinder or threaded control valve On cylinder or control valve with push-in connection Models with BSPP, BSPT and metric threads Models with NPT threads on request Plug-in models 3. Dimensions Standard applications require full flow rate performance and compact overall dimensions Small diameter cylinders require precise and accurate adjustment and minimum size Compact models Miniature models 4. Type of djustment Precise adjustment with locking nut ensuring the setting remains fixed Precise adjustment with screwdriver and protection against unwanted adjustment Models with external adjustment Models with recessed adjustment 5. Standard applications Banjo models Installation Configuration Tube output that can be positioned through 18 and swivels with the tube movement Models with swivel outlet Cylinder where access is difficult or where another function fitting is installed in the cylinder port In-line models 4-6

10 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. more precise and constant flow regulation is obtained when the regulator is fitted directly onto the cylinder.
