Butterfly valves with supervisory switches, OS&Y and NRS gate valves, check valves, strainers and sprinkler heads. Check the required approvals for the selected model, size and configuration.
Valve position and supervisory switches are matched to the fire-alarm monitoring system.
Approvals are checked for the exact valve type, size and configuration required by the project.
Check valves and alarm-valve functions are selected around flow direction and system hydraulics.
K-factor, response type, orientation and activation temperature are defined for the design.
Confirm handwheel access, stem travel and valve orientation before the surrounding pipework is fixed, especially for OS&Y valves and equipment in tight plant rooms.
Plan inspector’s test points, main drains and alarm-trim discharge so commissioning and periodic testing can be completed safely and without unnecessary system disruption.
Identify heated and unheated areas, outdoor exposure and corrosive surroundings so finishes, enclosures and installation details suit the actual location.
Filter by valve type, material or connection.
Share the system specification, size, connection and operating pressure. Add the required supervision, sprinkler characteristics and product approvals where applicable.
