Product Overview
▔▔The Atos KM-015-210 is a high-performance, modular (sandwich-plate) pressure relief valve designed for industrial hydraulic systems. Built to the ISO 4401 size 10 (CETOP 05) mounting standard, it provides reliable pressure limitation and overpressure protection in hydraulic circuits with flow rates up to 120 L/min.
Key Advantages
▔▔-
Modular Sandwich Design: Directly mounts beneath standard ISO 4401-05 directional valves, saving space and eliminating extra piping.
Precise Pressure Control: Smooth pressure adjustment mechanism with robust locking nut protection.
High Flow & Pressure Capacity: Handles system flow rates up to 120 L/min and pressure adjustments up to 210 bar (with maximum operating pressure up to 315/350 bar).
Industrial-Grade Reliability: Heavy-duty construction, high resistance to hydraulic shock, and long service lifespan under demanding continuous-duty cycles.
Easy Maintenance & Retrofit: Standardized footprint allows seamless replacement and minimal downtime.

FAQ
▔▔
Q1: What does the code "KM-015-210" stand for in Atos standard nomenclature?
Answer:
KM: Modular pressure relief valve size 10 (ISO 4401-05 / CETOP 05).
015: Valve configuration for single-stage relief action on line P discharging into line T.
210: Maximum adjustable setting range up to 210 bar.
Q2: What is the difference between Atos HM and KM series relief valves?
Answer: The primary difference lies in the nominal size and flow capacity:
HM / HMP Series: Designed for ISO 06 / CETOP 03 (NG6) mounting with flow rates up to 35–60 L/min.
KM Series: Designed for ISO 10 / CETOP 05 (NG10) mounting with flow rates up to 120 L/min.
