Operation and installation

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® safety valve must be equal or superior to the inside diameter of the HOSEGUARD® safety valve. Air hoses and pipes which are too small could impede successful closing of the HOSEGUARD® safety valve.
Long hoses or pneumatic tubes cause a flow restriction that could prevent the proper operation of HOSEGUARD® safety valves. As a general rule hoses with an internal diameter of 1/4 in shouldn’t be over 20 feet long, 3/8 in are limited to 50 feet and 1/2 In or larger should be within a 100 feet maximum length.
The rules above also apply to any mounted quick couplers and plugs, nipples, as these could negate the closing function of the HOSEGUARD® safety valve.
The inside diameter of the air hose or pipe installed before the HOSEGUARD® safety valve must be equal or superior to the inside diameter of the HOSEGUARD® safety valve.
If regulators or other components are mounted before the HOSEGUARD® safety valve, these components must have a higher flow than the HOSEGUARD® safety valve selected. Operation of the HOSEGUARD® safety valve should be thoroughly tested before first use and on a regular basis thereafter. To ensure the safe operation of the safety device simply simulate a hose breakage by replacing the tool with a ball valve. See the instruction manual for more information.

PROPER HOSEGUARD® SAFETY VALVE INSTALLATION
The HOSEGUARD® safety valve must be mounted between source of air supply and the flexible air hose
The HOSEGUARD® safety valve must be mounted at the end of a rigid feeding line
It is essential to ensure that the air is flowing in the correct direction (as per the arrows marked on the HOSEGUARD® safety valve), 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® safety valve, must be equal or superior than the inside diameter of the HOSEGUARD® safety valve

Caution

FACTS TO KNOW:
• OSHA standard No.1926.302(b)(7) states that: “All flexible hoses exceeding 1/2 inch inside diameter shall have a safety device at the source of supply or branch line to reduce pressure in case of hose failure.” TOPRING anti-hose whip safety valves satisfy this standard.
• *** ISO 4414-11 (5.4.5.11.1): “When failure of a hose assembly or plastic piping constitutes whiplash hazard, it shall be restrained or shielded by suitable means and/or an air fuse for compressed air shall be mounted.”
• Data for closing point (+/- 10 %) and other PSI available
• The air system should be operated only after the HOSEGUARD® safety valve has been rigorously tested and secured

Applications

• Compressed air distribution systems for medical, pharmaceutical, chemical, dental, food and beverage industries
