Frequently Asked Questions

What is the difference between a wet alarm valve and a deluge valve?

A wet alarm valve (ZSFZ) keeps the sprinkler piping filled with water and triggers the alarm on water flow. A deluge valve (ZSFM) stays closed under air or water pressure and floods the system only when a fire detection signal opens it - used for high-hazard areas requiring immediate large water discharge.

What standards do the sprinkler system components comply with?

Components are manufactured and tested in accordance with GB 5135 series and, on request, other international standards. Confirm the applicable standard for your project with our engineers.

What is the working pressure of the alarm valves?

Standard working pressure is 1.6 MPa with a testing pressure of 3.2 MPa. Size ranges typically cover DN50 to DN300 depending on the model.

Can the alarm valve groups be integrated with existing fire detection systems?

Yes. Deluge and pre-action valves support mechanical, pneumatic or electrical (DC24V solenoid) remote triggers and can be integrated with most fire alarm control panels.
