S HOSEGUARD ANTI HOSE WHIP When a fitting comes out from a pressurised hose or when a pressurised hose is ruptured, the hose starts blowing compressed air in an uncontrolled way. This causes the hose to whip and can result in: Injury Damage to pieces in production Dust being blown up from the floor Small components being blown around SAFETY SOLUTION FEATURES AND BENEFITS Safe Reliable, tamperproof Maintenance free Easy to install Light and compact Full, unrestricted flow of air in normal open position Complies with OSHA Regulation Standard 29CFR 1926.302 (Partial) Complies with ISO Standard 4414 (5.4.5.11.1) SOLUTION: ANTI HOSE WHIP TOPRING 316 HOSEGUARD offers simple but efficient protection to pneumatic systems in the event of a broken compressed air hose or pipe. The air supply is immediately shut off by the HOSEGUARD, should the volume of air exceed a set value. This value is factory preset and is set to allow normal air consumption when using air tools. Should the air consumption exceed the set value, e.g. the air line is severed, then the internal piston instantly shuts off the main flow. An integral bleed hole allows some air to flow though. This enables the line pressure to automatically reset the HOSEGUARD once the main break is repaired.

TOPRING anti hose whip safety valves satisfy this standard. 07_06_2016
HOSEGUARD ANTI HOSE WHIP INFORMATION REQUIRED TO SELECT THE RIGHT HOSEGUARD Pressure level at the HOSEGUARD Inside diameter and length of the air hose from the HOSEGUARD to the air tool Flow and pressure level needed to operate the air tool Please be aware that using theoretical values to select a HOSEGUARD is not advised. PROPER HOSEGUARD INSTALLATION The HOSEGUARD must be mounted at the beginning of a flexible air hose S By using both the available airflow value and the charts for HOSEGUARD closing points (next pages), the correct HOSEGUARD can be selected WARNING INSTALLATION GUIDELINES It is essential that the compressed air used is clean and dry The inside diameter of the mounted air hose or pipe INSTALLED AFTER the HOSEGUARD MUST BE EQUAL OR SUPERIOR to the inside diameter of the HOSEGUARD. Air hoses and pipes which are too small could prevent successful closing of the HOSEGUARD Very long lengths of air hose or pipe can result in an extreme pressure drop at its end point. It is essential that the HOSEGUARD has enough air flowing through it to close The rules above also apply to any mounted quick connect couplings, nipples etc. as these could negate the closing function of the HOSEGUARD The inside diameter of the air hose or pipe INSTALLED BEFORE the HOSEGUARD MUST BE EQUAL OR LARGER than the inside diameter of the HOSEGUARD If regulators or other components are mounted before the HOSEGUARD, these components must have a higher flow than the HOSEGUARD selected The operation of the HOSEGUARD thoroughly should be tested before use The HOSEGUARD must be mounted at the end of a rigid feeding line It is essential to ensure air is flowing in the correct direction (as per the arrows marked on the HOSEGUARD), otherwise the safety valve will not be able to close successfully The inside diameter of the mounted air hose or pipe installed before the HOSEGUARD, must be equal or larger than the inside diameter of the HOSEGUARD IMPORTANT The air system should be operated only after the HOSEGUARD has been rigourously tested and secured TOPRING 317
