The Complete Range of Fire Protection Gate Valves — DN50 to DN400
CA-FIRE manufactures a full range of gate valves and pipeline strainers for fire sprinkler, standpipe, deluge, and fire pump systems. Every product is built to fire protection service — full-bore, bi-directional, zero-restriction isolation with ductile iron bodies and fusion-bonded epoxy coating for corrosion resistance in continuously pressurised systems.
From the flanged OS&Y rising-stem valve required by NFPA 13 on sprinkler risers, to Victaulic-compatible grooved gate valves for fast commercial installation, to supervisory tamper-switch valves for FACP alarm integration — CA-FIRE covers all 9 products in a complete gate valve range for fire protection.
