Safety Shut-offs - for Pressure Measurement in the Expansion Vessel
IVAR.5580, IVAR.5585
Frequently Asked Questions
- What is a shut-off for an expansion vessel used for? It allows a pressure gauge to be safely connected directly to the expansion vessel and its pre-charge pressure to be checked or topped up without affecting the rest of the heating system.
- Can pressure be measured through the shut-off without draining the system? Yes, the shut-off isolates the vessel from the system only for the duration of the measurement, so there is no need to drain the heating water from the whole circuit.
