Valves for a building heating substation
A heat substation connects the district network to the building’s systems. Its valves decide whether equipment can be isolated and serviced without leaving the building cold.

Incoming connection
Supply and return entries get steel gate valves or ball valves rated for the network parameters. This is the boundary with the heat supplier, so the valves must be reliable.
Heat exchangers and pumps
Each exchanger and pump is isolated separately with ball or butterfly valves on both sides and check valves after the pumps, so equipment can be serviced one item at a time.
Drains and vents
Small valves for draining and venting go at low and high points. They are often forgotten in the schedule.
The package
Send the substation diagram and TAZ will select the full valve set with mating flanges.
