Butterfly Valves
Valves & Parts Signal Butterfly Valve (DN80 PN16) — Reports Its Own Position to Your Panel
The most dangerous valve is the one you can't see. When the control room thinks the main is open and it is closed, the fire meets a shut valve. Walking the line to check takes an hour, and nobody does it. This valve reports its own position. A waterproof microswitch flips the open or closed status to your panel the moment the handwheel moves, so the operator 500 meters away never walks down the line to check. One quarter turn of the worm gear handwheel, low torque, bi-directional EPDM or NBR sealing. QT450 wafer body, compact enough for tight riser spaces, DN50 to DN300 at PN16, 100% shell and seat pressure tested per GB/T 13927 or EN 12266-1. For fire mains, water supply, and industrial lines where position matters.

Fire Hydrants
Hydrants & Pump Connections Indoor Fire Hydrant Head SN65
Premium Ductile Iron SN65 High-Pressure Indoor Fire Hydrant Valve. Precision-machined, flexible grooved or flanged connection, and reliable sealing for commercial and industrial firefighting pipelines.
Hydrants & Pump Connections Self-Closing Anti-Collision Fire Hydrant (SSFT100/65) — Bolt-Shear Shutdown, Pressurized Repair
When a truck hits a standard fire hydrant, the street floods for days and the whole main has to go down for repairs. The SSFT100/65 is built for that exact moment. In a collision, two calibrated safety bolts shear cleanly and the internal valve shuts the water off immediately. The hydrant stands, the outlet stays dry, and your network keeps its pressure. When it is time to repair, the crew pulls the two sheared bolts and fits two new ones. No draining the line, no digging up a flanged valve. A built-in pressure regulating device gives progressive, smooth discharge at the outlets, and the automatic self-draining system keeps it frost-safe in winter. Ductile iron QT450 body, DN100/DN150, PN16, 2×KWS65 plus one DN100 outlet, hydrostatically tested to 2.4 MPa per GB 4452.

Fire Cabinets & Interfaces Aluminum Storz Fire Coupling (2.5" · German Standard) — Locks in One Hand, Stays Dry
A leaking hose joint buys the fire seconds. Threaded joints take two people and a wrench, and they drip at the seal while the line is under pressure. The Storz coupling locks in one hand. A quarter turn seats the self-sealing gasket and locks the joint, no tool, no drip. Under 1.6 MPa the seam stays dry, clear water or foam, and the line is ready to throw. Aluminum, brass or chrome, 2.5 inch (65 mm) German standard, barbed for lay-flat hose, factory pre-fitted or loose. For fire departments, marine lines, and any 65 mm line set from hydrant to nozzle.

Sprinklers & Alarm Valves Dry Alarm Valve (ZSFC Series)
The ZSFC dry alarm valve is the core control valve for dry-pipe and pre-action sprinkler systems. It stays closed by air (or nitrogen) pressure on the system side while the water side is held full, and opens automatically when an actuated sprinkler releases the system air, letting water fill the dry piping and reach the discharging sprinkler. Ideal for unheated buildings, cold-climate warehouses and pre-action systems.
Sprinklers & Alarm Valves ESFR Early Suppression Fast Response Sprinkler
ESFR (Early Suppression Fast Response) sprinklers deliver very high water discharge with fast thermal response, engineered to suppress or control severe fires in high-pile storage, warehouses and large industrial facilities.

Water Cannons
Extinguishing Water Cannons Auto-Tracking Fire Cannon (ZDMS Series) — Detects, Tracks and Extinguishes on Its Own
Fires in large high-ceiling spaces start when nobody is watching. By the time a person spots the flame it has already grown, and a hand-held hose may not reach a thirty-metre ceiling. The ZDMS watches for you. Multi-band infrared and ultraviolet sensors detect the flame, the cannon locks on and tracks the fire as it moves, then delivers a high-range concentrated jet that knocks it down. Fully automatic: detection, positioning and discharge, with manual remote override from PC, mobile APP or the central cabinet whenever you want a human in the loop. Rated flows from 5 to 30 L/s, customizable up to 150 L/s at 0.6-0.8 MPa. Horizontal 360°, vertical -90° to +30°, monitoring radius 40-65 m. Explosion-proof versions (Exde II BT4 Gb) are available for petrochemical plants and tank farms. For airports, exhibition centres, large warehouses, marine firefighting and anywhere the ceiling is too high for a hose.
Extinguishing Water Cannons Manual Fire Water Monitor (PS Series) — Aim Once, Lock It, Walk Away
The fire doesn't wait for you to hold that hose. A person standing on a line against the recoil, hour after hour, inside the heat of a tank fire, is the risk the monitor removes. The PS monitor throws 20 to 200 L/s 50 to 110 meters. The hand lever aims it, one pull changes straight jet to fog, and the self-locking gear holds your aim unmanned, so the operator aims once, locks it, and gets out of the zone. 0.8-1.2 MPa, horizontal 360°, vertical -30° to +70°, DN100 to DN200 inlet. T6 hard anodized aluminum or bronze for marine and salt-air service. For petrochemical yards, tank farms, airports, warehouses, fire trucks and marine firefighting.
