Storz Appliances

Quick-Coupling Storz Appliances for Fireground Efficiency

Storz Appliances are the heavy-flow gate valves, intake valves, elbows, and relief devices that keep large-diameter hose (LDH) water moving fast and safely on the fireground. Built around the industry-standard quarter-turn Storz coupling, these rugged aluminum and ductile iron appliances enable crews to connect hydrants, pump intakes, and relay lines in seconds, with no threading required. Whether you need a low-profile 5" intake valve with integrated pressure relief, a 4" gate valve elbow for tight streets, or a 30° swivel adapter to redirect supply lines, Darley stocks proven options from Harrington and Kochek Company, each appliance is engineered for high PSI, smooth waterway flow, and NFPA compliance, giving pump operators precise control while protecting apparatus and personnel. Outfit your tankers and pumpers with Storz appliances that deliver speed, safety, and interoperability when every second counts.
