Landing Valve 65mm

Its 65mm outlet integrates a GOST-unique coupling with proprietary threading and seal grooves, distinct from BS/ANSI standards. This design ensures airtight connection only with GOST-certified hoses, eliminating cross-standard leaks-a critical compliance feature for regions following former Soviet technical protocols. The coupling's precision machining locks into hoses via a half-turn bayonet action, speeding up emergency connections by 30% vs. generic valves.

Engineered to withstand rough handling in industrial or conflict-affected regions, the valve body uses a reinforced cast brass core wrapped in high-tensile steel. It passes GOST impact tests (10J force at -5°C), resisting cracks from accidental drops or debris strikes-unlike lightweight aluminum alternatives. Internal components are secured with anti-vibration fasteners, ensuring functionality after prolonged exposure to mechanical stress.

Coated with GOST-specified zinc-nickel alloy (12μm thickness) and sealed with nitrile rubber gaskets, it resists corrosion from saltwater, industrial chemicals, and humid tropical climates-critical for coastal nations or areas with heavy industrial activity. The strainer screen uses 316 stainless steel, enduring acidic or alkaline fluid exposure that would degrade standard steel mesh.

Features a dual-position lever (open/closed) with tactile feedback, allowing gloved operation even in low-light conditions. The valve opens fully with a 90° turn, delivering maximum flow (≥1500 L/min) per GOST 5798 standards. A built-in pressure relief valve prevents system overpressure, while the compact flange design fits legacy GOST-compatible wall brackets-simplifying retrofits in older buildings across post-Soviet states.
