Warning

This document does not give sufficient information to install

the product in a safe manner.

See the relevant system Installation and Maintenance

Instructions for full details.

The F50C valve may be installed in any position, but the flow should

be in the direction of the arrow on the valve body.

When used as an isolating valve in a steam meter impulse line, it is

important to install the valve on the centre line of the flowmeter

rather than below it, so that the valve is in steam rather than water.

Safety

Warning

Your attention is drawn to Safety information leaflet IM-GCM-10.
