Valvole & sottovalvole per serbatoi gpl

These external valves are designed for use as a primary relief valve on above ground domestic and small industrial bulk lpg containers. When used in conjunction with a check device (isolation valve) permits the exchange of the relief valve without the necessity of evacuating the container. Note: this action must be carried out by trained personnel carefully following our operating instructions.

. Relief valves provide “pop action” performance.
. “tell tale” hole is incorporated on the connection thread, which indicates the check is closed and the valve may be removed.
. A metal to metal make up on the check device allows for a “signal flow” of gas to act as a reminder that the container is unprotected when the valve is removed.
. Check device has generous flow channels with a low pressure drop for optimum performance.
