Line Valves & Zone Valve Boxes

Silbermann manufactures medical gas line shut-off valves, zone valve boxes, and area valve service units (AVSUs) for hospitals and healthcare facilities.

What is the difference between line valves and zone valve boxes?

Line shut-off valves and zone valve boxes are essential components of medical gas pipeline systems; they control the supply of medical gas or vacuum through an individual pipeline and allow isolation at a defined point in the system.

A zone valve box houses one or more shut-off valves that control the supply to a designated hospital area, allowing each service to be shut off independently during emergencies or maintenance.

Configuration Options

Silbermann offers configurations to suit each healthcare facility and pipeline installation. Depending on the product, available options include:

• A range of valve sizes.
• Recessed or surface-mounted valve boxes.
• Aluminium doors or pull-out removable inspection windows.
• Optional line pressure gauges.
• Configurations for medical gases and vacuum, including oxygen, medical air and nitrous oxide.

Standards

The range includes products designed to meet the relevant requirements of NFPA 99, EN ISO 7396-1 and G-01, with selected AVSU configurations designed to meet HTM 02-01 requirements.
