Products Description

CA-FIRE Cast Iron Landing Valve
Tailor-made for inside-building suppression networks, this landing-valve hydrant guarantees an instant, pressurised water supply the moment the fire brigade arrives. Certified to every applicable Russian GOST and fire-code clause, the unit is slim enough to recess into stairwells, corridor walls or mid-landing niches in housing blocks, business centres, warehouses and plants alike.
A one-turn, precision shut-off valve and forged-metal hose union let crews couple and charge a line in seconds, while the internal flow stabiliser keeps pressure surges and rate fluctuations within tight tolerances. The whole body-stem, seat and outlet-is cast from low-porosity, salt-fog-tested alloys, so rust and scale never shorten its life cycle, even in humid HVAC zones. The result is a space-smart, low-maintenance hydrant that satisfies both national and international fire-protection statutes and stands ready for decades of rapid-response service.

Typical Application Scenarios
Residential Buildings in the Russian Far East: The DN50 specification is suitable for fire risers in unit buildings. It can respond quickly at -30℃ and cooperate with Russian-style fire hoses to extinguish incipient household fires.
Chemical Workshops in Central Asia: The DN65 specification is used in workshop fire-fighting systems. Its corrosion-resistant coating can resist chemical vapor erosion, and the large-flow design meets the fire-extinguishing needs of equipment.
Shopping Malls in CIS Countries: The two specifications are used in combination - DN50 for store areas and DN65 for large spaces such as atriums, complying with local fire regulations.
